    KRISTIN MILLS, ADMINISTRATOR (ESTATE OF
    CHERYL MILLS) v. HARTFORD HEALTHCARE
    CORPORATION ET AL.
    (SC 20763)
    (SC 20764)
    (SC 20765)
    McDonald, D’Auria, Mullins, Ecker and Seeley, Js.
    Syllabus
    The plaintiff, the administrator of the estate of the decedent, C, sought to
    recover damages from the named defendant, H Co., which operates
    Hartford Hospital, and the defendant physicians, R, B, D, and F, for the
    allegedly wrongful death of C. In March, 2020, shortly after the onset
    of the COVID-19 pandemic, C went to the emergency room at a hospital
    in Norwich complaining of a sore throat and a headache. The emergency
    room staff suspected that C was experiencing a myocardial infarction.
    Because the Norwich hospital did not have a cardiac catheterization
    lab, C was transferred to Hartford Hospital, where such facilities are
    available. At that hospital, C was examined by R, an interventional
    cardiologist. H Co., however, had recently modified its protocols due
    to the pandemic, and patients who were suspected of having COVID-
    19 were not to be admitted to the hospital’s catheterization lab until
    they tested negative for COVID-19, unless their physical symptoms dic-
    tated the need for emergency catheterization. R was concerned that C
    could have COVID-19 and doubted that she was suffering from a myocar-
    dial infarction, insofar as he believed that C’s symptoms were most
    consistent with COVID-19 induced myocarditis or myopericarditis rather
    than a myocardial infarction. Accordingly, R developed a treatment plan
    pursuant to which C would be tested for COVID-19 and her admission
    to the catheterization lab would be deferred pending the receipt of a
    negative COVID-19 test result. A COVID-19 diagnostic test was adminis-
    tered on March 21, 2020, and, while it was in process over the next
    several days, B, D, and F became involved in C’s care. On March 24,
    2020, C’s test result came back as negative. F was the only physician
    responsible for C’s care after the receipt of the negative test result. On
    March 25, 2020, F ordered that C undergo a coronary angiogram in the
    hospital’s catheterization lab, but C died of a myocardial infarction
    before the procedure was administered. The plaintiff alleged that the
    defendant physicians, and, through them, H Co., were negligent and
    grossly negligent in their treatment of C, insofar as C died after she was
    misdiagnosed as having non-life-threatening myocarditis or myopericar-
    ditis, when she actually was suffering from a life-threatening myocardial
    infarction. The defendants moved to dismiss the plaintiff’s action, claim-
    ing that they were immune from liability and suit under Executive Order
    No. 7V, § 6, which was issued by Governor Ned Lamont in April, 2020,
    and which confers on health care professionals and health care facilities
    ‘‘immunity from suit for civil liability for any injury or death alleged to
    have been sustained because of . . . acts or omissions undertaken in
    good faith while providing health care services in support of the [s]tate’s
    COVID-19 response . . . .’’ The defendants also claimed that they were
    immune under the provision (42 U.S.C. § 247d-6d) of the federal Public
    Readiness and Emergency Preparedness Act (PREP Act) that confers
    immunity from suit and liability for injuries sustained as a result of the
    application or use of certain pandemic countermeasures, such as COVID-
    19 diagnostic tests. The trial court ultimately granted the motions to
    dismiss with respect to the claims directed at the defendant physicians’
    acts or omissions that occurred before the receipt of C’s negative COVID-
    19 test result on March 24, 2020, but denied one of the motions to
    dismiss with respect to claims directed at acts or omissions occurring
    after that time. As to the immunity conferred under Executive Order
    No. 7V, the court reasoned that, before the negative test result was
    received, the defendant physicians were providing health care services
    in support of the state’s response to the pandemic because, at that time,
    they had a good faith belief that they may be treating an actual COVID-
    19 patient, but the defendant physicians could not claim to be providing
    health care services in support of the state’s COVID-19 response after
    they received the negative test result. Similarly, with respect to the
    immunity conferred under the PREP Act, which, unlike Executive Order
    No. 7V, affords immunity for gross negligence, as well as negligence,
    the trial court determined that the defendants were immune for only
    those acts and omissions, whether negligent or grossly negligent, that
    occurred before the receipt of the negative COVID-19 test result because
    they related to, and arose out of, a COVID-19 diagnostic countermeasure,
    namely, the administration of C’s COVID-19 diagnostic test. Accordingly,
    because R, B, and D were not involved in C’s treatment after the receipt
    of the negative COVID-19 test result, the court dismissed all of the claims
    against them, leaving F as the only remaining individual defendant based
    on his role in C’s care after the receipt of the negative COVID-19 test
    result on March 24, 2020. The plaintiff, H Co., and F filed separate
    appeals. On appeal, the plaintiff challenged the court’s dismissal of the
    counts directed at R, B, and D, alleging negligence before C’s negative
    COVID-19 test result was received. H Co. and F challenge the court’s
    decision not to dismiss the plaintiff’s claims relating to acts or omissions
    after the receipt of the negative COVID-19 test result. Held:
    1. The trial court correctly determined that, under Executive Order No.
    7V, the defendants were immune for any negligent acts or omissions
    occurring before, but not after, the receipt of C’s negative COVID-19 test
    result, and, therefore, the court properly dismissed the counts alleging
    negligence against R, B, and D, and properly declined to dismiss the
    count alleging negligence with respect to F’s acts or omissions after the
    receipt of C’s negative COVID-19 test result:
    a. This court concluded that Executive Order No. 7V, § 6, confers immu-
    nity from suit and liability only for acts and omissions that are undertaken
    in good faith and in connection with the provision of health care services
    in support of the state’s COVID-19 response, which necessarily would
    include those undertaken for the prevention, diagnosis, or treatment of
    COVID-19, and that a health care provider or facility seeking immunity
    under that provision is required to demonstrate a nexus between the
    alleged negligence and the services rendered in support of the state’s
    COVID-19 response.
    In determining the scope of the immunity conferred by Executive Order
    No. 7V, this court applied the usual principles of statutory interpretation
    in construing the language of the executive order, and, because this court
    determined that the provision therein conferring immunity to covered
    individuals and facilities for ‘‘acts or omissions undertaken in good faith
    while providing health care services in support of the [s]tate’s COVID-
    19 response’’ was ambiguous, it looked to the circumstances surrounding
    the order’s promulgation and to the public policy that the order was
    designed to implement.
    When Governor Lamont issued Executive Order No. 7V, the nature of
    COVID-19 was poorly understood, the belief that hospitals were about
    to be overwhelmed was widespread, and the evident purpose of the
    immunity provision was to facilitate the implementation of certain poli-
    cies that would augment Connecticut’s health care workforce by assuring
    health care professionals and facilities that, in light of the uncertainties
    surrounding the diagnosis, treatment, and prevention of COVID-19, and
    in view of the compelling need to keep health care facilities open and
    operating, they would not be held liable for their acts and omissions
    undertaken in good faith and in support of the state’s COVID-19 response.
    In light of the language of the immunity provision and the policies that
    it was intended to advance, this court rejected both a narrow interpreta-
    tion of Executive Order No. 7V, § 6, pursuant to which a health care
    provider is immune from liability and suit only for acts or omissions
    undertaken while treating a patient for COVID-19, and a broad interpreta-
    tion, pursuant to which a health care provider is immune from liability and
    suit for any acts or omissions undertaken while the provider’s services
    coincide with the effective period of the declared public health emer-
    gency, regardless of whether the acts or omissions are connected to
    those services, and, instead, it adopted an interpretation between those
    two ends of the spectrum pursuant to which immunity is conferred when
    connected to the health care provider’s services in support of the state’s
    COVID-19 response, even if the defendant was not treating the patient
    for COVID-19.
    This interpretation of Executive Order No. 7V, § 6, was supported by
    the plain language in the second part of the immunity provision, providing
    that the scope of the immunity includes, but is not limited to, ‘‘acts or
    omissions undertaken because of a lack of resources, attributable to the
    COVID-19 pandemic, that renders the health care professional or heath
    care facility unable to provide the level or manner of care that otherwise
    would have been required in the absence of the COVID-19 pandemic
    and which resulted in the damages at issue,’’ insofar as that language
    plainly requires the act or omission to have a connection to the COVID-
    19 pandemic for immunity to apply, and construing the first part of
    the immunity provision to require a similar nexus between the alleged
    negligence and the COVID-19 pandemic created a harmonious and consis-
    tent whole.
    b. The plaintiff could not prevail on her claim that the trial court improp-
    erly had dismissed the counts of her complaint alleging negligence with
    respect to the defendant physicians’ acts or omissions occurring before
    the receipt of C’s negative COVID-19 test result:
    Notwithstanding the plaintiff’s argument that, but for the defendant physi-
    cians’ alleged misdiagnosis, C’s COVID-19 status would have been
    deemed irrelevant for purposes of the plaintiff’s negligence claim, and
    the fact that, if C had been experiencing a myocardial infarction, the
    defendant physicians should have promptly admitted her to the hospital’s
    cardiac catheterization lab, the immunity conferred by Executive Order
    No. 7V does not turn on whether the defendant physicians’ acts or
    omissions were negligent but, rather, on whether those acts or omissions
    had a connection to health care services provided in support of the
    state’s COVID-19 response.
    In the present case, the plaintiff offered no evidence to dispute the
    affidavits submitted by the defendant physicians, in which they attested
    that C’s COVID-19 status was a material factor in diagnosing C and
    deciding on her treatment and care, the defendant physicians’ reliance
    on the COVID-19 protocol instituted by H Co. underscored the fact
    that their acts or omissions, regardless of whether they were negligent,
    occurred in the course of providing health care services in support of
    the state’s COVID-19 response, and the diagnosis and treatment of a
    patient with health care complications that the provider believed in good
    faith were caused by COVID-19 clearly constituted acts or omissions
    connected to the provision of health care services in support of the
    state’s COVID-19 response for purposes of Executive Order No. 7V.
    Moreover, there was no merit to the plaintiff’s claim that Executive
    Order No. 7V requires an objectively reasonable belief that the health
    care provider’s provision of services was in support of the state’s COVID-
    19 response, as the immunity provision therein includes no such require-
    ment, and the plaintiff’s claim conflates the issues of immunity and
    liability and fails to contemplate that, in the present case, the alleged
    misdiagnosis of C and C’s COVID-19 status were inextricably linked,
    insofar as the defendant physicians submitted undisputed evidence that
    they believed that C’s symptoms were caused by COVID-19, and their
    treatment plan was informed by that provisional diagnosis.
    c. F and H Co. could not prevail on their claims that the trial court
    incorrectly had determined that they were not immune under Executive
    Order No. 7V for F’s allegedly negligent acts and omissions after the
    receipt of C’s negative COVID-19 test result:
    The receipt of C’s negative test result broke any meaningful connection
    between F’s treatment of C and his provision of health care services in
    support of the state’s COVID-19 response because, at that point, F simply
    was providing treatment to a patient who, three days earlier, had received
    test results possibly indicating a myocardial infarction, and, although
    the provisional diagnosis of a possible COVID-19 infection had caused
    the delay in diagnosing and treating C’s true condition, COVID-19 had
    no bearing on the nature of the health care services that were rendered
    after the negative test result was received, thereby rendering immunity
    unavailable under the terms of Executive Order No. 7V for acts and
    omissions occurring after that point in time.
    Moreover, contrary to F’s and H Co.’s claims that COVID-19 continued
    to bear on the nature of the health care services that F provided despite
    the receipt of C’s negative COVID-19 test, the decisions made concerning
    C’s care after COVID-19 had been ruled out were not dictated by the
    COVID-19 diagnosis but, rather were the result of learning that C did
    not have COVID-19 and the delay driven by suspicion of a COVID-19
    induced condition having come to an end.
    Furthermore, there was no merit to F’s claim that he and H Co. were
    immune from liability because there was nothing that he reasonably
    could have been expected to do to prevent C’s death once her negative
    test result was received, as that claim conflated immunity and liability,
    or his claim that this court’s conclusion would lead to an absurd result
    by bifurcating the immunity analysis on the basis of whether the care
    F provided occurred before or after the receipt of C’s COVID-19 test
    result, and there was nothing in the record to support the contention of
    H Co. that its COVID-19 protocol hampered the defendant physicians’
    ability to provide treatment to C after the receipt of her negative COVID-
    19 test result.
    d. This court declined to address certain additional issues regarding the
    governor’s statutory and constitutional authority to confer immunity
    from suit and liability for medical malpractice:
    Although the parties cited constitutional considerations in connection
    with their arguments as to the scope of immunity afforded under Execu-
    tive Order No. 7V, § 6, the plaintiff did not challenge the governor’s
    authority to confer such immunity, and, although this court ordered
    supplemental briefing on this issue and related issues, which were of a
    sufficiently public character to warrant this court’s review, supplemental
    briefing, in light of its limitations, did not provide a sufficiently robust
    platform to address those issues.
    Accordingly, this court assumed, without deciding, that the governor
    was legally authorized to confer the immunity at issue through an execu-
    tive order.
    2. The trial court incorrectly concluded that, under the federal PREP Act,
    the defendants were immune from suit and liability for their allegedly
    negligent and grossly negligent acts or omissions occurring before the
    receipt of C’s negative COVID-19 test result, and, accordingly, this court
    reversed the trial court’s decision insofar as that court dismissed the
    counts of the complaint alleging grossly negligent acts or omissions by
    R, B, and D prior to the receipt of the negative COVID-19 test result:
    a. The trial court incorrectly concluded that the defendants were immune
    from suit and liability under the PREP Act for their conduct, including
    their allegedly grossly negligent acts or omissions, occurring before the
    receipt of the negative COVID-19 test result:
    In determining whether PREP Act immunity applies, courts focus on the
    claims as they are pleaded in the plaintiff’s complaint.
    The immunity conferred by the PREP Act, as it relates to what constitutes
    a covered countermeasure, is narrow in scope and far less encompassing
    than the immunity conferred by Executive Order No. 7V, as the PREP
    Act does not apply to all medical services provided in an attempt to
    diagnose, treat, or prevent the spread of COVID-19, and, although a
    countermeasure under the PREP Act includes the administration of a
    COVID-19 diagnostic test, it does not include protocols or policies
    designed or implemented for the prevention or control of COVID-19, such
    as H Co.’s protocol with respect to the admission of patients suspected
    of having COVID-19 to the hospital’s cardiac catheterization lab.
    In the present case, the plaintiff alleged, inter alia, that the defendant
    physicians were both negligent and grossly negligent in failing to diagnose
    C with a myocardial infarction, and Executive Order No. 7V, § 6, does
    not confer immunity for allegedly grossly negligent acts or omissions.
    The mere fact that the defendant physicians administered and used a
    COVID-19 test did not, in and of itself, dictate whether they should
    proceed with treatment while the test result was pending, and that deci-
    sion was driven, rather, by the defendant physicians’ provisional COVID-
    19 diagnosis and H Co.’s protocol, and there would have been no delay
    attributable to the defendant physicians if they had immediately diag-
    nosed her with a myocardial infarction, despite suspecting that she suf-
    fered from COVID-19, and had immediately admitted her to the hospital’s
    cardiac catheterization lab while the COVID-19 test result was pending,
    as the plaintiff alleged they should have done.
    Accordingly, in light of the plaintiff’s allegations in her complaint, the
    defendant physicians’ gross negligence was not causally related to and
    did not arise out of the administration or use of the COVID-19 diagnostic
    test within the meaning of the PREP Act.
    b. The trial court correctly concluded that F and H Co. were not immune
    from suit and liability under the PREP Act for F’s allegedly negligent
    acts or omissions occurring after the receipt of C’s negative COVID-19
    test result:
    In light of this court’s conclusion that the PREP Act does not confer
    immunity from suit and liability for the allegedly negligent conduct of
    R, B, and D before the receipt of C’s negative COVID-19 test result, the
    PREP Act did not afford F immunity for his allegedly negligent conduct
    after receipt of the test result because, if there was no allegation of any
    causal relationship between the administration of the COVID-19 test and
    the plaintiff’s allegations of negligence relating to acts or omissions
    before the receipt of the test result for purposes of the PREP Act, the
    receipt of the test result could not have created such a connection.
    Accordingly, the plaintiff was entitled to proceed on the counts of her
    complaint alleging gross negligence as to all of the defendants and the
    counts of her complaint alleging negligence as to F and H Co.

    Opinion
    ECKER, J. This court recently discussed the legality
    of certain executive orders issued by Governor Ned
    Lamont in response to the catastrophic effects of the
    pandemic caused by the spread of the potentially fatal
    coronavirus disease 2019 (COVID-19). See Casey v.
    Lamont, 
    338 Conn. 479
    , 481–83, 
    258 A.3d 647
     (2021).
    The present appeals require us to consider the scope
    and application of Executive Order No. 7V, which pur-
    ports to confer immunity on health care providers in
    connection with Governor Lamont’s March, 2020 decla-
    ration of a public health emergency.1 We also must
    address similar questions with respect to 42 U.S.C.
    § 247d-6d, a provision in the federal Public Readiness
    and Emergency Preparedness Act (PREP Act) that con-
    fers immunity from suit and liability for injuries sus-
    tained as the result of the application or use of certain
    pandemic countermeasures (e.g., COVID-19 diagnos-
    tic tests).2
    These issues arise in the context of a wrongful death
    action filed by the plaintiff, Kristen Mills, the daughter
    of the decedent, Cheryl Mills, and the executor of her
    estate. The complaint alleges that the decedent died
    after she was misdiagnosed as having a non-life-threat-
    ening heart condition, when she actually was suffering
    from a life-threatening heart condition. According to
    the complaint, her death was the result of negligent and
    grossly negligent medical care provided by the named
    defendant, Hartford HealthCare Corporation, doing
    business as Hartford Hospital (hospital), and the defen-
    dant physicians, Asad Rizvi, Melissa Ferraro-Borgida,
    Brett H. Duncan, and William J. Farrell.3 The defendants
    moved to dismiss the complaint on the ground that they
    were immune from suit and liability under Executive
    Order No. 7V and the PREP Act in light of the role that
    COVID-19 had played in their diagnosis and treatment
    decisions. The trial court concluded that the defendants
    had immunity under Executive Order No. 7V for the
    allegedly negligent acts and omissions undertaken
    before the receipt of the decedent’s negative COVID-
    19 test result and immunity under the PREP Act for the
    allegedly grossly negligent acts and omissions under-
    taken during that same period. The court consequently
    granted the motions to dismiss the counts against Rizvi,
    Ferraro-Borgida, and Duncan. The court further con-
    cluded, however, that the only physician responsible
    for the decedent’s care after receipt of the negative
    test result, Farrell, did not have immunity under either
    Executive Order No. 7V or the PREP Act. The trial court
    accordingly denied the motion to dismiss the counts
    alleging negligence and gross negligence against Farrell.
    In SC 20765, the plaintiff appeals from the trial court’s
    judgment insofar as it granted the defendants’ motions
    to dismiss. In SC 20763 and SC 20764, Farrell and the
    hospital, respectively, appeal from the denial of their
    motions to dismiss.4 We disagree with the trial court’s
    conclusions only insofar as it determined that the defen-
    dants were entitled to immunity under the PREP Act.
    We therefore reverse the trial court’s judgment dismiss-
    ing counts V, VI, and VII of the complaint. We affirm
    the judgment in all other respects.
    The following facts are taken primarily from the alle-
    gations in the complaint, supplemented by certain addi-
    tional facts contained in affidavits submitted by the
    parties in connection with the motions to dismiss. See,
    e.g., Carpenter v. Daar, 
    346 Conn. 80
    , 97–99 n.12, 
    287 A.3d 1027
     (2023). On the morning of March 21, 2020,
    the decedent, who worked as a registrar in the emer-
    gency room at Backus Hospital (Backus) in Norwich,
    went to the Backus emergency room complaining of
    having a sore throat and a headache for the past few
    days.5 She informed the staff about her medical history,
    including the fact that she had a heart murmur and
    needed a heart valve replacement. She denied feeling
    any pain in her chest, arm or back, or any shortness of
    breath at rest. In light of concerning indications on her
    cardiac monitor, Backus staff had the decedent undergo
    an electrocardiogram at approximately 12:08 p.m. That
    test showed rapid atrial fibrillation and an ‘‘ST eleva-
    tion.’’ Theresa Adams, an emergency medicine physi-
    cian at Backus, suspected that the decedent was
    experiencing an ‘‘ST elevation myocardial infarction’’
    (STEMI) or, in common parlance, a heart attack.
    A patient suffering from an acute STEMI should
    receive coronary intervention in a cardiac catheteriza-
    tion lab,6 ideally within ninety minutes. Because Backus
    did not have the facilities to provide cardiac catheteriza-
    tion, Adams called the hospital, where such facilities
    are available for both diagnostic and interventional pur-
    poses, to arrange for the decedent’s transfer.
    The hospital had recently modified its protocols due
    to concerns relating to the spread of COVID-19. One
    such modification directed health care providers to
    ‘‘avoid admitting patients who were suspected of having
    COVID-19 to [the hospital’s] cardiac catheterization lab
    . . . until they had tested negative, unless their physi-
    cal symptoms dictated the need for emergency catheter-
    ization.’’7 (Emphasis added.) The purpose of the
    modified protocol was to prevent the spread of COVID-
    19 to other patients and staff and to conserve supplies
    of personal protective equipment.
    At approximately 12:12 p.m., Adams spoke to Rizvi,
    the interventional cardiologist on call in the hospital’s
    catheterization lab. In light of the notable absence of
    cardiac symptoms in the decedent’s presentation, her
    medical history, and her high risk of exposure to
    COVID-19 based on her employment in a hospital emer-
    gency room, Rizvi opined that the decedent did not
    meet the criteria for transfer to the catheterization lab.
    Rizvi expressed concern that the decedent could have
    COVID-19 and doubted that she was suffering from a
    STEMI. Rizvi recommended that the decedent be trans-
    ferred to the hospital’s emergency room.
    Before her transfer from Backus to the hospital at
    approximately 1:14 p.m., the decedent’s troponin levels8
    reached 8.6 nanograms per milliliter, and Backus emer-
    gency department staff believed that the decedent was
    critically ill with a high probability of imminent or life-
    threatening deterioration. Updated medical information
    was electronically relayed to Rizvi.
    After the decedent’s transfer to the hospital, Rizvi
    examined her and continued to suspect that she was
    suffering from a COVID-19 induced condition. Rizvi was
    aware that patients suffering from certain viruses,
    including COVID-19, could present with an ST elevation
    and abnormal troponin levels as the result of virus
    induced myocarditis or myopericarditis, which are non-
    life-threatening cardiac inflammatory conditions. Rizvi
    developed a plan for the decedent’s treatment, pursuant
    to which she would be tested for COVID-19, remain in
    isolation pending receipt of the test result, and undergo
    an echocardiogram. At approximately 3:27 p.m., Rizvi
    recommended that admission to the catheterization lab
    be deferred until COVID-19 could be ruled out.
    Hospital staff administered a COVID-19 test to the
    decedent at approximately 5:18 p.m. on March 21, 2020.
    It was sent to a state laboratory for processing, which,
    at that time, took several days.
    Over the next two days, March 22 and 23, 2020, Fer-
    raro-Borgida, Duncan, and Farrell, also cardiologists
    working at the hospital, became involved in the care
    of the decedent. Each agreed with Rizvi’s recommenda-
    tion to defer the decedent’s transfer to the catheteriza-
    tion lab pending receipt of her COVID-19 test because
    her history and current presentation indicated to them
    that she most likely was suffering from COVID-19
    related myocarditis. Ferraro-Borgida noted in the dece-
    dent’s chart that she was not suffering from chest pain
    but from a sore throat and headache. Ferraro-Borgida
    also noted that the decedent would need a ‘‘full [echo-
    cardiogram] for evaluation of valves and cardiac [cathe-
    terization] to assess coronary anatomy.’’ Duncan later
    noted that the decedent ‘‘had absolutely no chest symp-
    toms’’ and that her symptoms were ‘‘most consistent
    with myocarditis.’’ He further noted that they were
    ‘‘[w]aiting for [COVID-19] testing to become negative
    but [did] suggest cardiac catheterization before hospital
    discharge.’’ Farrell, the last to examine the decedent
    on March 23, 2020, noted that she was ‘‘asymptomatic
    with no signs of heart failure or ongoing chest pain.’’
    He also noted that, ‘‘[o]nce [the decedent has been]
    ruled out for [a COVID-19] infection she will undergo
    a right and left heart [catheterization]. [The decedent]
    is frustrated by the delay but understands the rationale
    for infectious disease evaluation . . . .’’
    On March 24, at 7:40 p.m., the decedent’s COVID-19
    test result was reported as negative. The next morning,
    on March 25, 2020, at 6:06 a.m., Farrell ordered that the
    decedent undergo a coronary angiogram in the catheter-
    ization lab later that day. The purpose of the angiogram
    was not to treat an acute STEMI but to evaluate the
    decedent’s coronary anatomy. Before the angiogram
    could be administered, however, the decedent suffered
    ‘‘a sudden [pulseless electrical activity] arrest’’ and died.
    The decedent’s death certification listed the cause of
    death as a myocardial infarction.
    The plaintiff thereafter brought this wrongful death
    action against the defendants pursuant to General Stat-
    utes § 52-555. In an eight count complaint, the plaintiff
    alleged that the individual defendants, and, through
    them, the hospital, were negligent and grossly negligent
    in their treatment of the decedent.9 The defendants filed
    three separate motions to dismiss: one addressing the
    counts against Rizvi, one addressing the counts against
    Ferraro-Borgida and Duncan, and one addressing the
    counts against Farrell. All of the defendants claimed
    that they were immune from suit under Executive Order
    No. 7V because their treatment of the decedent was
    undertaken in good faith and in support of the state’s
    COVID-19 response and that they were immune under
    the PREP Act because the treatment was related to a
    COVID-19 countermeasure.10 See footnotes 1 and 2 of
    this opinion. The defendants offered, in support of their
    motions, affidavits from each of the defendant physi-
    cians and from Adam Steinberg, the hospital’s vice pres-
    ident for medical affairs, as well as the decedent’s
    hospital records. The plaintiff submitted an affidavit
    from her medical expert, who attested that the defen-
    dant physicians had misdiagnosed the decedent’s condi-
    tion and that the standard, emergency treatment for a
    STEMI, the condition actually suffered by the decedent,
    had not changed, regardless of a patient’s COVID-19
    status.
    After the motions to dismiss were filed, the trial court
    requested additional briefing on the issue of whether
    receipt of the decedent’s negative COVID-19 test result
    terminated any immunity conferred by Executive Order
    No. 7V and the PREP Act. The defendants responded
    that immunity was not terminated because the treat-
    ment decisions made by Farrell after receipt of the
    negative test result were dictated by the treatment plan
    put in place when the decedent was admitted to the
    hospital with a suspected COVID-19 infection. They sub-
    mitted an additional affidavit by Farrell in support of
    this claim.
    The trial court issued a memorandum of decision,
    concluding that receipt of the negative COVID-19 test
    result marked the dividing line between immunity and
    potential liability. The court reasoned that, ‘‘before [the
    decedent’s] COVID-19 test came back negative, the
    defendants were providing health care services in sup-
    port of the state’s response to the pandemic because,
    at that time, the defendants had a good faith belief
    that they may be treating an actual COVID-19 patient.’’
    Accordingly, the court concluded that the defendants
    were immune from suit and liability under Executive
    Order No. 7V for their allegedly negligent acts or omis-
    sions before receipt of the negative test result. The
    court further concluded that, because ‘‘the defendants
    [could] no longer claim [that] they were ‘providing
    health care services in support of the [s]tate’s COVID-
    19 response’ ’’ after receipt of the negative test result,
    they were not entitled to immunity under the executive
    order from suit and liability for negligent acts or omis-
    sions occurring thereafter.
    The trial court reached similar conclusions with
    respect to immunity under the PREP Act, which, unlike
    Executive Order No. 7V, provides immunity for gross
    negligence. The court determined that the PREP Act
    conferred immunity on the defendants for all acts and
    omissions, negligent or grossly negligent, occurring
    before receipt of the negative COVID-19 test result
    ‘‘because such claims plainly are related to, and arise
    out of, a COVID-19 diagnostic countermeasure, specifi-
    cally, [the decedent’s] COVID-19 test.’’ The court dis-
    missed the claims of gross negligence arising from
    conduct occurring before the receipt of the test result.
    As with Executive Order No. 7V, the court concluded
    that PREP Act immunity did not extend to acts or omis-
    sions occurring after receipt of the test result because,
    ‘‘by that time, [the decedent’s] COVID-19 diagnostic
    tests were at an end.’’
    To summarize, the trial court granted the defendants’
    motions to dismiss with respect to the claims directed
    at the defendants’ acts or omissions occurring before
    7:40 p.m. on March 24, 2020. The court denied the
    motions with respect to the claims directed at the defen-
    dants’ acts or omissions occurring after that time.
    The defendants filed motions for clarification, in
    which they pointed out that there was no dispute that
    Rizvi, Ferraro-Borgida, and Duncan had not been
    involved in the decedent’s treatment after receipt of
    the negative COVID-19 test result and, therefore, that
    the claims against those defendants must or should
    have been dismissed in their entirety. The plaintiff con-
    sented to the motions. The trial court granted the
    motions and rendered judgment dismissing all of the
    claims against Rizvi, Ferraro-Borgida, and Duncan, leav-
    ing Farrell as the only remaining individual defendant
    based on his role in the decedent’s care after 7:40 p.m.
    on March 24, 2020.
    The plaintiff appealed insofar as the trial court dis-
    missed the counts pertaining to the defendants’ acts
    or omissions before receipt of the decedent’s negative
    COVID-19 test result. Farrell and the hospital separately
    appealed from the trial court’s decision denying in part
    their motions to dismiss with respect to acts or omis-
    sions after receipt of the negative COVID-19 test result.11
    Resolution of each of these appeals turns on the ques-
    tion of whether the trial court properly construed and
    applied the immunity provisions of Executive Order
    No. 7V and the PREP Act.
    Our review of the trial court’s decision is guided by
    well established principles. We previously have recog-
    nized that ‘‘[t]rial courts addressing motions to dismiss
    for lack of subject matter jurisdiction pursuant to [Prac-
    tice Book § 10-30 (a) (1)] may encounter different situa-
    tions, depending on the status of the record in the case.
    . . . [I]f [as here] the complaint is supplemented by
    undisputed facts established by affidavits submitted in
    support of the motion to dismiss . . . the trial court,
    in determining the jurisdictional issue, may consider
    these supplementary undisputed facts and need not
    conclusively presume the validity of the allegations of
    the complaint. . . . Rather, those allegations are tem-
    pered by the light shed on them by the [supplementary
    undisputed facts]. . . . If affidavits [or] other evidence
    submitted in support of a defendant’s motion to dismiss
    conclusively establish[es] that jurisdiction is lacking,
    and the plaintiff fails to undermine this conclusion with
    counteraffidavits; see Practice Book § [10-30 (a)]; or
    other evidence, the trial court may dismiss the action
    without further proceedings.’’ (Citation omitted; inter-
    nal quotation marks omitted.) Carpenter v. Daar, supra,
    
    346 Conn. 98
     n.12. Conversely, if the allegations of the
    complaint and the supplementary facts produced by
    the defendant do not conclusively establish that juris-
    diction is lacking, the court must deny the motion to
    dismiss. Unless the resolution of the motion to dismiss
    has required the trial court to resolve factual disputes,
    our review of a trial court’s ruling on a motion to dismiss
    is plenary. See id., 97, 98 n.12.
    I
    EXECUTIVE ORDER NO. 7V
    We begin with the challenges to the trial court’s deci-
    sion involving the claims of immunity under Executive
    Order No. 7V. Our first task is to determine the scope
    of the immunity conferred by the executive order and
    then to apply that interpretation to the allegations in
    the complaint and the supplementary undisputed facts.
    We have not previously addressed the principles that
    govern our interpretation of executive orders. The
    Appellate Court has held that ‘‘[a]pplying the principles
    of statutory interpretation to [an] executive order is
    [appropriate] because [such an] order has the full force
    and effect of law.’’ Prime Management, LLC v. Arthur,
    
    217 Conn. App. 737
    , 750, 
    290 A.3d 401
     (2023);12 see
    General Statutes § 28-9 (b) (1) (any order issued by
    governor pursuant to § 28-9 (b) ‘‘shall have the full force
    and effect of law upon the filing of the full text of such
    order in the office of the Secretary of the State’’). Other
    jurisdictions have applied the same reasoning. See Bas-
    sidji v. Goe, 
    413 F.3d 928
    , 934 (9th Cir. 2005) (‘‘[a]s is
    true of interpretation of statutes, the interpretation of
    an [e]xecutive [o]rder begins with its text’’); United
    States v. Abu Marzook, 
    412 F. Supp. 2d 913
    , 922 (N.D.
    Ill. 2006) (‘‘[t]he [c]ourt interprets [e]xecutive [o]rders
    in the same manner that it interprets statutes’’); Coble
    v. Ventura County Health Care Agency, 
    73 Cal. App. 5th 417
    , 425, 
    288 Cal. Rptr. 3d 431
     (2021) (‘‘[t]he con-
    struction of an executive order presents an issue akin
    to an issue of statutory interpretation—one that pre-
    sumably presents a question of law for our independent
    review on appeal’’ (internal quotation marks omitted));
    In re Murack, 
    957 N.W.2d 124
    , 128 (Minn. App. 2021)
    (applying principles of statutory interpretation to emer-
    gency executive orders); SRI Eleven 1407 Broadway
    Operator, LLC v. Mega Wear, Inc., 
    71 Misc. 3d 779
    , 795,
    
    144 N.Y.S.3d 289
     (2021) (‘‘[a]s is true of interpretation
    of statutes, the interpretation of an [e]xecutive [o]rder
    begins with its text, which must be construed consis-
    tently with the [o]rder’s object and policy’’ (internal
    quotation marks omitted)). We find the reasoning of
    these cases persuasive and, therefore, apply the usual
    principles of statutory interpretation to our construc-
    tion of Executive Order No. 7V.
    Section 6 of Executive Order No. 7V provides in rele-
    vant part: ‘‘Notwithstanding any provision of the Con-
    necticut General Statutes or any other state law,
    including the common law, or any associated regula-
    tions, rules, policies, or procedures, any health care
    professional or health care facility shall be immune
    from suit for civil liability for any injury or death alleged
    to have been sustained because of the individual’s or
    health care facility’s acts or omissions undertaken in
    good faith while providing health care services in sup-
    port of the [s]tate’s COVID-19 response, including but
    not limited to acts or omissions undertaken because
    of a lack of resources, attributable to the COVID-19
    pandemic, that renders the health care professional or
    health care facility unable to provide the level or manner
    of care that otherwise would have been required in the
    absence of the COVID-19 pandemic and which resulted
    in the damages at issue . . . .’’ This immunity does not
    extend to, among other things, ‘‘acts or omissions that
    constitute . . . gross negligence . . . .’’ Executive
    Order No. 7V, § 6 (April 7, 2020). The immunity was
    deemed applicable to acts or omissions occurring at
    any time during the public health and civil preparedness
    emergency declared on March 10, 2020.
    The sentence conferring immunity contains two basic
    parts, connected by the phrase ‘‘including but not lim-
    ited to . . . .’’ Id. Because the defendants in this case
    do not claim immunity under the second part of this
    provision, relating to a lack of resources, we focus
    our attention primarily on the immunity conferred to
    covered individuals and facilities for ‘‘acts or omissions
    undertaken in good faith while providing health care
    services in support of the [s]tate’s COVID-19 response
    . . . .’’13 Id. Moreover, because the plaintiff does not
    contest the element of good faith, our specific focus is
    on the requirement that the injury or death be sustained
    because of the individual’s or health care facility’s acts
    or omissions ‘‘while providing health care services in
    support of the [s]tate’s COVID-19 response . . . .’’ Id.
    Both sides advance arguments as to why this phrase
    does or does not apply to the particular facts in the
    present case, but neither party has clearly articulated
    a general meaning that they ascribe to the phrase. We
    therefore consider the broad contours of this phrase
    before considering the parties’ context specific argu-
    ments.
    The text is reasonably susceptible to a range of rea-
    sonable interpretations. The narrowest interpretation
    would understand the phrase ‘‘while providing health care
    services in support of the [s]tate’s COVID-19 response’’
    to mean that a health care provider is immune from
    suit and liability only for acts or omissions undertaken
    while treating the injured party for COVID-19. Under the
    broadest interpretation, the phrase reasonably could
    mean that a health care provider is immune from suit
    and liability for any acts or omissions undertaken during
    the period in which the health care provider is providing
    services in support of the state’s COVID-19 response
    (i.e., while those services coincide with the effective
    period of the declared public health emergency), regard-
    less of whether the acts or omissions are connected to
    those services. Between these two extremes, the phrase
    also reasonably could mean that immunity applies when
    the acts or omissions causing the injury were connected
    to the health care provider’s services in support of the
    state’s COVID-19 response, even if the health care pro-
    vider was not treating the injured party for COVID-19.
    Because the immunity provision of Executive Order
    No. 7V is ambiguous, we look for interpretive guidance
    to the circumstances surrounding its promulgation and
    to the public policy that it was designed to implement.
    Cf. State v. Pond, 
    315 Conn. 451
    , 467, 
    108 A.3d 1083
    (2015) (‘‘[w]hen a statute is not plain and unambiguous,
    we . . . look for interpretive guidance to the . . . cir-
    cumstances surrounding its enactment . . . [and] to
    the legislative policy it was designed to implement’’
    (internal quotation marks omitted)).
    The circumstances existing at the beginning of the
    worldwide COVID-19 pandemic are well known. Although
    it was clear by early 2020 that COVID-19 was a danger-
    ous and highly contagious disease, the mechanisms of
    the disease, its symptomatology, the methods by which
    the virus spread, and effective strategies for treatment,
    control, and prevention were all poorly understood.
    See Fraihat v. United States Immigration & Customs
    Enforcement, 
    16 F.4th 613
    , 619 (9th Cir. 2021) (observ-
    ing that steps taken by United States Immigration and
    Customs Enforcement at outset of pandemic were
    taken ‘‘in the face of scientific uncertainty and a con-
    stantly developing understanding of COVID-19’’);

    rounded the extent, seriousness and nature of COVID-
    19’’). At this time and at all times relevant to the present
    case, no COVID-19 vaccine was yet available; see Dixon
    v. De Blasio, 
    566 F. Supp. 3d 171
    , 177 and nn. 4–7

    virus—the type ordered in the present case—typically
    took several days to obtain results. See T. Li, ‘‘Privacy

    It was widely believed in March, 2020, that medical
    providers and hospitals throughout the United States
    were about to be overwhelmed with COVID-19 patients.

    Confronted with these circumstances, on March 10,
    2020, Governor Lamont declared a public health emer-
    gency and a civil preparedness emergency throughout
    the state pursuant to General Statutes §§ 19a-131a and
    28-9.15 See Casey v. Lamont, supra, 
    338 Conn. 483
    . He
    thereafter issued a series of executive orders, including
    Executive Orders Nos. 7U and 7V, both of which addressed
    the health care crisis.16 Governor Lamont formally declared
    that it was ‘‘necessary to supplement Connecticut’s
    health care workforce and the capacity of health care
    facilities to deliver [lifesaving] care by requesting the
    assistances of health care professionals who [had] not
    previously maintained liability coverage; facilitating the
    deployment of volunteer and out-of-state professionals;
    and calling [on health care] professionals to perform
    acts that they would not perform in the ordinary course
    of business . . . .’’ Executive Order No. 7U (April 5,
    2020). Governor Lamont further determined that, ‘‘in
    order to encourage maximum participation in efforts
    to expeditiously expand Connecticut’s health care
    workforce and facilities capacity, there exists a compel-
    ling state interest in affording such professionals and
    facilities protection against liability for good faith
    actions taken in the course of their significant efforts
    to assist in the state’s response to the current public
    health and civil preparedness emergency . . . .’’ 
    Id.
    The evident purpose of the immunity provision of Exec-
    utive Order No. 7V was to facilitate the implementation
    of these policies by assuring the relevant health care
    professionals and facilities that, in light of the uncertain-
    ties surrounding the diagnosis, treatment, and preven-
    tion of COVID-19,17 and in view of the compelling need
    to keep health care facilities open and operating, they
    would not be held liable for such acts and omissions,
    as long as they acted in good faith and in support of
    the state’s COVID-19 response.
    With this background in mind, we first consider the
    narrowest interpretation of Executive Order No. 7V,
    under which immunity is available only when the medi-
    cal practitioner was treating the injured party for
    COVID-19. We reject this interpretation because it
    would fall far short of fulfilling the public policy under-
    lying the order. It is not difficult to imagine ‘‘good faith
    actions taken in the course of [health care workers’]
    significant efforts to assist in the state’s response’’ to
    the COVID-19 pandemic that could result in the injury
    or death of persons who were not being treated for
    COVID-19. 
    Id.
     For example, if a patient sought treatment
    in a hospital’s emergency department for a broken leg
    and contracted a COVID-19 infection from another
    patient who was being treated for COVID-19, we can
    perceive no reason why Governor Lamont would have
    wanted the hospital—which was making a good faith
    effort to assist in the state’s COVID-19 response by
    treating COVID-19 patients—to be held liable merely
    because it was not treating the patient with the broken
    leg for COVID-19. The purpose of Executive Order No.
    7V was to allow health care facilities to provide such
    services without the fear of being subjected to lawsuits.
    At the other extreme, we also find unpersuasive an
    expansive interpretation of Executive Order No. 7V that
    provides immunity for all negligent acts or omissions
    undertaken by health care professionals and facilities
    during the period in which they were providing services
    in support of the state’s COVID-19 response, regardless
    of the connection between that act or omission and the
    response to COVID-19. Such immunity would extend
    to circumstances in which, for example, a patient under-
    going a surgical procedure by a fully staffed, equipped,
    and trained surgical team was injured as a result of
    the surgeon’s negligence. We see no evidence that the
    governor intended to provide immunity in such circum-
    stances merely because the hospital also was providing
    services in support of the state’s COVID-19 response
    that had no material effect on the patient’s treatment.
    Such a broad interpretation would raise other prob-
    lems, as well. It would run afoul of the principle that
    ‘‘statutes in derogation of the common law are [to be]
    strictly construed . . . .’’18 (Internal quotation marks
    omitted.) Chadha v. Charlotte Hungerford Hospital,
    
    272 Conn. 776
    , 789, 
    865 A.2d 1163
     (2005). An immunity
    that sweeps so broadly also may be of questionable
    constitutionality on various grounds. For example,
    when this court addressed the constitutional limits of
    the authority granted to the governor under § 28-9 (b)
    in Casey, we recognized that the governor’s statutory
    authority under § 28-9 (b) (7) to ‘‘take such other steps
    as are reasonably necessary in the light of [a declared
    public health] emergency to protect the health, safety
    and welfare of the people of the state’’ is constitutional
    only to the extent that it authorizes the governor to
    take steps that are necessary to protect the health,
    safety, and welfare of the people from the dangers
    ‘‘implicated by this particular serious disaster. The gov-
    ernor would not, for example, be able to issue an execu-
    tive order forbidding restaurants from selling unhealthy
    foods during the COVID-19 pandemic.’’ (Emphasis omitted.)
    Casey v. Lamont, supra, 
    338 Conn. 508
    . We explained
    that, if § 28-9 (b) (7) were interpreted as authorizing
    the governor to issue executive orders that are not
    necessary for that narrow purpose, the statute would be
    an unconstitutional delegation of legislative authority
    because there would be no limiting principle to guide
    the exercise of that authority.19 See id., 504–505. The
    broadest interpretation of Executive Order No. 7V would
    thus be of questionable constitutionality because, among
    other reasons, it would not be linked to the specific
    dangers posed by the COVID-19 pandemic as identified
    in Executive Order Nos. 7U and 7V, namely, the danger
    that health care providers and facilities would be unable
    to meet the expanded demand for services due to liabil-
    ity concerns arising from the use of health care profes-
    sionals who are not insured or do not have insurance
    coverage in this state.
    The interpretation between these two extremes mini-
    mizes the foregoing concerns.20 An immunity that applies
    when the acts or omissions that caused the injury are
    connected to the health care provider’s services in sup-
    port of the state’s COVID-19 response, even if the defen-
    dant was not treating the injured party for COVID-19,
    maintains a close fit between the grant of public health
    emergency authority in § 28-9, the terms of the execu-
    tive order, and the express policies underlying that
    order.
    We find additional textual support for this interpreta-
    tion of the first part of the immunity provision when
    we turn our attention to the second part of that provi-
    sion. The provision states that the scope of the immunity
    includes, but is not limited to, ‘‘acts or omissions under-
    taken because of a lack of resources, attributable to
    the COVID-19 pandemic, that renders the health care
    professional or heath care facility unable to provide the
    level or manner of care that otherwise would have been
    required in the absence of the COVID-19 pandemic and
    which resulted in the damages at issue . . . .’’ Execu-
    tive Order No. 7V, § 6 (April 7, 2020). This language
    plainly requires the act or omission to have a connection
    to the COVID-19 pandemic for immunity to apply. Con-
    struing the first part of the immunity provision to
    require a similar nexus between the alleged negligence
    and the COVID-19 pandemic thus creates a harmonious
    and consistent whole. See, e.g., Harpaz v. Laidlaw
    Transit, Inc., 
    286 Conn. 102
    , 130, 
    942 A.2d 396
     (2008)
    (‘‘[w]e are obligated to search for a construction of the
    statute that makes a harmonious whole of its constit-
    uent parts’’ (internal quotation marks omitted)).
    Our interpretation also avoids the violation of a basic
    canon of statutory interpretation that arises from a
    broad interpretation of the ‘‘while providing health care
    services’’ clause as conferring immunity for any acts or
    omissions undertaken during the period in which the
    health care provider is providing services in support of
    the state’s COVID-19 response (i.e., the duration of the
    public health emergency). If all a defendant has to do
    to establish immunity under that clause is prove that the
    pertinent act or omission occurred during the relevant
    period when it was providing COVID-19 support ser-
    vices, and is not required to establish that the act or
    omission was connected to the provision of those ser-
    vices, then the specific circumstances that fall within
    the ‘‘including but not limited to’’ clause would be ren-
    dered entirely superfluous. See, e.g., American Promo-
    tional Events, Inc. v. Blumenthal, 
    285 Conn. 192
    , 203,
    
    937 A.2d 1184
     (2008) (‘‘[i]nterpreting a statute to render
    some of its language superfluous violates cardinal prin-
    ciples of statutory interpretation’’). The nature of or
    reason for the act or omission (a lack of resources or
    any other relevant reason) would not matter, only when
    it occurred.
    We therefore conclude, subject to the caveat that we
    articulate in part I C of this opinion, that § 6 of Executive
    Order No. 7V confers immunity from suit and liability
    only for acts and omissions that are undertaken in good
    faith and in connection with the provision of such ser-
    vices. Health care services in support of the state’s
    COVID-19 response necessarily would include those
    undertaken for the prevention, diagnosis, or treatment
    of COVID-19. The language of the immunity provision
    and the policies the immunity is expressly intended to
    advance require a defendant to demonstrate a nexus
    between the alleged negligence and the services ren-
    dered in support of the state’s COVID-19 response.
    Mindful of these broad contours of the part of the immu-
    nity provision at issue, we now turn to the parties’
    arguments as to its application to the present circum-
    stances.
    A
    The plaintiff contends in her appeal that the trial
    court should not have found against her as to the events
    prior to receipt of the negative COVID-19 test result be-
    cause COVID-19 is irrelevant to the negligence alleged
    in her complaint, which rests on her claim that the
    defendants caused the decedent’s death as a result of
    their misdiagnoses of her medical condition and their
    corresponding failure to render proper treatment. The
    plaintiff asserts that, ‘‘but for the misdiagnosis, [the
    decedent’s] COVID-19 status would have been consid-
    ered irrelevant, and the fact that she was experiencing
    a STEMI would have compelled the defendants to get
    her into the [catheterization] lab quickly.’’ The plaintiff
    accepts that this misdiagnosis could have been a prod-
    uct of the defendants’ subjective, good faith belief that
    the decedent likely was suffering from a COVID-19
    induced heart condition. She contends, however, that
    the defendants would be entitled to immunity only if
    they reasonably believed that the decedent’s COVID-
    19 status was relevant to her diagnosis and treatment.
    The plaintiff argues on the basis of this premise that
    the defendants cannot establish that the acts or omis-
    sions at issue were undertaken ‘‘while providing health
    care services in support of the [s]tate’s COVID-19
    response’’ for two related reasons: (1) under the hospi-
    tal’s COVID-19 protocol, the determination of whether
    a patient was exhibiting physical symptoms dictating
    the need for emergency catheterization was made with-
    out regard to the patient’s COVID-19 status, and (2) in
    the absence of undisputed evidence proving otherwise,
    the court was bound to assume the truth of the plaintiff’s
    allegations that the defendants misdiagnosed the dece-
    dent with myocarditis or myopericarditis rather than
    a STEMI, and, thus, the delay in her transfer to the
    catheterization lab for an emergency procedure was
    not connected to the provision of health services in
    support of the state’s COVID-19 response.21 We disagree.
    The plaintiff has offered no evidence to call into dis-
    pute the defendants’ affidavits attesting that the dece-
    dent’s COVID-19 status was a material factor in their
    diagnosis of the decedent and their decisions on her
    treatment and care. The defendants recommended a
    COVID-19 test to confirm or cast doubt on that diagno-
    sis. Although the defendants’ immunity does not hinge
    on the existence of the hospital’s COVID-19 protocol,
    the fact that they deferred the decedent’s admission
    to the catheterization lab in reliance on that protocol
    underscores the fact that their acts or omissions, negli-
    gent or not, occurred while providing health care ser-
    vices in support of the state’s COVID-19 response. The
    aim of that protocol was to protect patients from expo-
    sure to the potentially deadly virus and to conserve
    scarce personal protective equipment necessary to pro-
    tect desperately needed staff. The diagnosis and treat-
    ment of a patient with health care complications that
    the health care provider believed in good faith to be
    caused by COVID-19, as well as the prevention of the
    spread of COVID-19 to other patients, clearly constitute
    acts or omissions connected to the provision of health
    care services in support of the state’s COVID-19 re-
    sponse.
    The plaintiff’s argument that the immunity provision
    requires an objectively reasonable belief that the defen-
    dants’ provision of services is in support of the state’s
    COVID-19 response suffers from three principal flaws,
    two legal and one factual in nature. First, although the
    provision expressly imposes a good faith requirement,
    it says nothing about the objective reasonableness of
    that belief. Cf. General Statutes § 33-756 (a) (‘‘[e]ach
    member of the board of directors, when discharging
    the duties of a director, shall act: (1) [i]n good faith;
    and (2) in a manner the director reasonably believes
    to be in the best interests of the corporation’’). Second,
    the defendants’ argument collapses the distinction
    between immunity and liability by conflating two very
    different issues, namely, (1) whether the defendants are
    immune for their allegedly negligent acts and omissions,
    and (2) whether the defendants were in fact negligent.
    Under the plaintiff’s theory, the immunity would never
    be necessary because a court could not determine that
    the defendants are entitled to immunity unless it also
    finds that there is no negligence (i.e., when the act or
    omission at issue was found to be objectively reason-
    able and, thus, no liability would attach). Third, and
    most important, the plaintiff’s position fails to appreci-
    ate that, in the present case, the alleged misdiagnosis
    and the decedent’s COVID-19 status were inextricably
    intertwined—the defendants submitted undisputed evi-
    dence that they believed that the decedent’s symptoms
    were caused by COVID-19, and their treatment plan
    (including the delay in transferring her to the catheter-
    ization lab) was informed by that provisional diagnosis.
    The plaintiff contends that it is necessary to require
    proof that the defendants’ misdiagnosis was objectively
    reasonable because, otherwise, any defendant could
    avoid liability in any case simply by asserting their sub-
    jective, but unreasonable, belief that a patient had
    COVID-19. This concern carries little weight. It ignores
    the requirement of good faith, which may be disputed
    in some cases (but is not in the present case). It also
    overlooks the fact that there will be situations in which
    a patient’s COVID-19 status will be irrelevant to the
    care and treatment at issue. There will, in addition, be
    cases in which a patient alleges that the defendants’
    acts or omissions constitute gross negligence or wilful
    misconduct, both of which are outside the scope of the
    immunity afforded under the executive order.
    Mindful of the caveat we articulate in part I C of
    this opinion, we conclude that the trial court properly
    dismissed the counts alleging negligence for acts or
    omissions occurring before receipt of the decedent’s
    negative COVID-19 test result (i.e., counts I, II, and III
    of the complaint).
    B
    Farrell and the hospital claim in their appeals that
    the trial court incorrectly determined that the immunity
    conferred by Executive Order No. 7V does not apply
    to Farrell’s acts and omissions after the receipt of the
    decedent’s negative COVID-19 test result. They contend
    that the treatment that Farrell provided after that time
    was dictated entirely by the treatment that had been
    prescribed when the decedent was initially admitted to
    the hospital, and nothing that they could have done
    after receipt of the test result could have prevented
    the decedent’s death. More particularly, the hospital
    contends that Governor Lamont did not ‘‘intend for
    frontline health care professionals to be sued for adher-
    ing to a plan dictated by COVID-19 and put in place
    before they ever saw the patient. Such results would
    be inconsistent with Governor Lamont’s purposes to
    encourage providers to take whatever action [was]
    needed to combat the pandemic and to expand the
    health care workforce because it would discourage par-
    ticipation rather than encourage it and encourage
    wasteful, defensive medicine.’’ Farrell likewise con-
    tends that ‘‘it would be incongruous to interpret the
    scope of the executive order as being limited solely to
    the care and treatment of patients [who] test positive
    for COVID-19. . . . If the governor meant to limit the
    scope of immunity to the treatment of COVID-19 posi-
    tive patients only, he could have done so but chose not
    to as a policy matter.’’ We disagree.
    Under the circumstances of this case, receipt of the
    test result broke any meaningful connection between
    Farrell’s treatment of the decedent and his provision
    of health care services in support of the state’s COVID-
    19 response. At that point, Farrell simply was providing
    treatment to a patient who, three days earlier, had
    received test results possibly indicating a STEMI.
    Although the clinical diagnosis of a possible COVID-19
    infection had caused the delay in diagnosing and treat-
    ing the decedent’s true condition, COVID-19 had no
    bearing on the nature of the health care services that
    were rendered after 7:40 p.m. on March 24, 2020. There-
    fore, immunity was no longer available under the terms
    of Executive Order No. 7V.
    Farrell and the hospital dispute this conclusion,
    arguing that COVID-19 did bear on the nature of the
    health care services that Farrell provided after receipt
    of the negative COVID-19 test. They argue that Farrell’s
    treatment of the decedent was entirely dictated by the
    treatment decisions that were made when the decedent
    was admitted to the hospital with a clinical diagnosis
    of possible COVID-19. To support this claim, they rely
    on Farrell’s affidavit, in which he stated that his order
    at 6:06 a.m. on March 25, 2020, directing that the dece-
    dent be admitted to the catheterization lab, ‘‘was not a
    new treatment decision and plan, but rather was [the]
    completion of the treatment plan established on March
    21, 2020, dictated as a result of COVID-19 concerns
    of myocarditis simulating a STEMI presentation and
    concerns of COVID-19 exposure and spread risk,’’ and
    that, ‘‘[a]s of the time of [his] care and treatment, the
    initial event, whatever it was, was a completed event.’’
    Farrell further contends that, by the time the defendants
    received the negative test result, there was no treatment
    that they reasonably could have been expected to pro-
    vide that would have reversed the completed cardiac
    event that the decedent had suffered on March 21, 2020,
    or prevented her death.
    Neither of these arguments is persuasive. First, the
    decisions that were made concerning the decedent’s treat-
    ment once COVID-19 was ruled out were not ‘‘dictated
    by’’ the clinical COVID-19 diagnosis but, rather, were
    the result of learning that the decedent did not have
    COVID-19 and the delay driven by suspicion of a COVID-
    19 induced condition having come to an end. COVID-
    19 had no apparent bearing on the treatment of the
    decedent’s heart condition as of 7:40 p.m. on March 24,
    2020. Second, with respect to the contention that the
    defendants are immune from suit and liability for Far-
    rell’s acts and omissions occurring after the receipt of
    the negative test result because there was nothing that
    he reasonably could have been expected to do at that
    point to prevent the decedent’s death, the claim con-
    flates immunity with liability by arguing, in effect, that
    they are immune because Farrell was not negligent.22
    As we previously explained in part I A of this opinion,
    the immunity conferred by Executive Order No. 7V does
    not turn on whether the defendants’ acts or omissions
    were negligent but on whether their acts or omissions
    had a connection to health care services provided in
    support of the state’s COVID-19 response. There is no
    such connection with respect to events after receipt of
    the negative COVID-19 test.
    Farrell contends that our conclusion would lead to an
    absurd result because he provided care for the decedent
    both before and after receipt of the test, and it makes
    no sense to bifurcate the immunity analysis under these
    circumstances. He points out that, ‘‘[a]lthough the [trial]
    court found that . . . Farrell had immunity for follow-
    ing the established plan of care put in place [when] he
    became involved in the case, it also [found] that he did
    not have immunity for following that same established
    plan of care after receipt of the negative COVID-19 test.’’
    This contention overlooks that the facts changed upon
    receipt of the test result. Once COVID-19 was ruled
    out as a cause of the decedent’s heart condition, the
    treatment of her heart condition going forward was
    not being provided in support of the state’s COVID-19
    response and, therefore, was not within the scope of
    the immunity conferred by Executive Order No. 7V.
    Moreover, contrary to the premise of Farrell’s con-
    tention, the plaintiff is seeking to hold the defendants
    liable for the acts that they actually undertook or failed
    to undertake in treating the decedent, not for devising
    a treatment plan for what would happen if the decedent
    received a negative COVID-19 test result. Regardless of
    who initially devised the treatment plan in the event
    that the result came back negative, Farrell was the
    physician who provided the treatment, and the plaintiff
    seeks to hold him liable for his failure to provide the
    treatment allegedly required by the applicable standard
    of care.23
    Taking a different tack, the hospital argues that the
    defendants are entitled to immunity because the hospi-
    tal’s COVID-19 protocols hampered the defendants’ abil-
    ity to provide treatment to the decedent after receipt
    of her negative COVID-19 test result. The hospital relies
    on Steinberg’s statements in his affidavit that, ‘‘[d]uring
    the [t]reatment [p]eriod, [the hospital] was engaged in
    various steps to conserve personal protective equip-
    ment . . . including, but not limited to, minimizing in-
    person contact between patients and hospital personnel
    and limiting the number of hospital personnel in contact
    with patients suspected of having COVID-19,’’ and that
    the hospital’s COVID-19 protocols required it to ‘‘avoid
    administration of echocardiograms to patients who did
    not demonstrate an absolute clinical need . . . .’’ There
    is no support in the record establishing that the factors
    identified by Steinberg played any role in hampering
    the defendants’ treatment of the decedent after receipt
    of the negative COVID-19 test result. None of the affida-
    vits includes any such statement of fact.24
    For the foregoing reasons, we conclude that the trial
    court correctly determined that Farrell and, through
    him, the hospital are not immune from suit and liability
    under Executive Order No. 7V for the plaintiff’s claims
    related to the health care services that they provided
    to the decedent after receipt of her negative COVID-19
    test result. It therefore properly denied Farrell’s motion
    to dismiss on that ground.
    C
    We end our discussion regarding immunity under
    Executive Order No. 7V with an important caveat. Our
    role in the present appeal is limited to interpreting and
    applying Executive Order No. 7V to the undisputed facts.
    Although the parties have cited constitutional consider-
    ations in connection with their arguments as to the
    scope of immunity afforded under Executive Order No.
    7V, the plaintiff has not challenged on appeal the gover-
    nor’s statutory or constitutional authority to confer
    immunity from liability for medical malpractice in the
    first place.25 Cf. Casey v. Lamont, supra, 
    338 Conn. 483
    (holding that § 28-9 provided authority for governor
    to issue certain executive orders and that statute so
    construed passed constitutional muster). Given the
    common-law nature of an action for medical malprac-
    tice; see, e.g., Greenwald v. Van Handel, 
    311 Conn. 370
    ,
    383, 
    88 A.3d 467
     (2014); Golden v. Johnson Memorial
    Hospital, Inc.,

    ,
    cert. denied, 
    259 Conn. 902
    , 
    789 A.2d 990
     (2001); it
    remains an open question whether § 28-9 (b) (1), which
    authorizes the governor to ‘‘modify or suspend’’ a ‘‘stat-
    ute, regulation or requirement,’’ permits the issuance
    of an executive order modifying or suspending the
    ‘‘common law,’’ as Executive Order No. 7V purports to
    do. See footnote 15 of this opinion (setting forth rele-
    vant text of § 28-9 (b)). This omission naturally raises
    a colorable question as to whether the legislature in
    fact delegated such authority to the governor, and, if
    not, whether any other source of authority supported
    the order as to this matter. See F. Perry & M. Weismann,
    ‘‘Rationing Healthcare During a Pandemic: Shielding
    Healthcare Providers from Tort Liability in Uncharted
    Legal Territory,’’ 
    30 U. Miami Bus. L. Rev. 142
    , 174–79
    (2021) (discussing whether gubernatorial executive
    orders providing immunity shields raise enforceability
    issues, including whether state governor is legally
    authorized to issue executive order). Mindful that the
    resolution of these issues not only would impact liability
    arising from the COVID-19 pandemic but also could
    provide useful guidance for responses to potential
    future public health emergencies, we solicited supple-
    mental briefs on whether this court could and should
    address these important matters.26 The parties and the
    responding amici curiae naturally took different views
    on this matter.
    Although these questions are of a sufficiently ‘‘public
    character’’ to warrant this court initiating review; (emphasis
    omitted) Blumberg Associates Worldwide, Inc. v.
    Brown & Brown of Connecticut, Inc., 
    311 Conn. 123
    ,
    158, 
    84 A.3d 840
     (2014); we have determined that their
    resolution should await more appropriate circum-
    stances. It is evident that the limitations of supplemental
    briefing in this case do not afford a sufficiently robust
    platform to address the legal issues raised sua sponte
    by the court, including, but not limited to, whether
    medical malpractice in a wrongful death action should
    be characterized as statutory or common law in nature;

    see also footnote 25 of this opinion; and whether the
    common law could be abrogated through the modifica-
    tion or suspension of statutes, especially when § 6 of
    Executive Order No. 7V does not identify any statutes
    or indicate that it intends to ‘‘modify’’ or ‘‘suspend’’ any
    existing law, as directed in § 28-9 (b) (1). Cf. Executive
    Order No. 7V, §§ 2 through 5 (April 7, 2020) (identifying
    statutes to be ‘‘modified’’ and specifying nature of modi-
    fication). We also are mindful of the concern that the
    posture of the present case failed to afford a sufficient
    opportunity for the development of an evidentiary
    record that might be required for this court to properly
    adjudicate these issues at this stage. Accordingly, in
    our analysis of the issue as presented to us, we have
    assumed, without deciding, that the governor was
    legally authorized to create and confer the immunity at
    issue in the present case, as provided in § 6 of Executive
    Order No. 7V, and leave the resolution of that question
    to another day.
    II
    FEDERAL PREP ACT
    The question that remains is whether the plaintiff’s
    claims that do not come within the scope of Executive
    Order No. 7V nonetheless must be dismissed under
    the immunity provision of the federal PREP Act. The
    specific claims at issue are the count alleging negligence
    against Farrell relating to treatment following receipt
    of the negative COVID-19 test result, addressed in part
    I B of this opinion, and the counts alleging gross negli-
    gence as to all the defendants.27 As we will explain, the
    scope of the immunity provided by the PREP Act is
    different from—and much narrower than—that con-
    ferred by Executive Order No. 7V and does not cover
    the claims presently under consideration.
    ‘‘Congress enacted the PREP Act in 2005 [t]o encour-
    age the expeditious development and deployment of
    medical countermeasures during a public health emer-
    gency by allowing the [United States Secretary of Health
    and Human Services (secretary)] to limit legal liability
    for losses relating to the administration of medical
    countermeasures such as diagnostics, treatments, and
    vaccines.’’ (Internal quotation marks omitted.) Cannon
    v. Watermark Retirement Communities, Inc., 
    45 F.4th 137
    , 139 (D.C. Cir. 2022). ‘‘The immunity is triggered
    by a declaration from the [s]ecretary identifying the
    threat to public health, the period during which immu-
    nity is in effect, and other particulars.’’ 
    Id.
    The PREP Act provides in relevant part that ‘‘a cov-
    ered person shall be immune from suit and liability
    under Federal and State law with respect to all claims
    for loss caused by, arising out of, relating to, or
    resulting from the administration to or the use by an
    individual of a covered countermeasure if a declaration
    . . . has been issued with respect to such countermea-
    sure.’’28 (Emphasis added.) 42 U.S.C. § 247d-6d (a) (1)
    (2018). The immunity conferred by the PREP Act
    ‘‘applies to any claim for loss that has a causal relation-
    ship with the administration to or use by an individ-
    ual of a covered countermeasure, including a causal
    relationship with the design, development, clinical test-
    ing or investigation, manufacture, labeling, distribution,
    formulation, packaging, marketing, promotion, sale,
    purchase, donation, dispensing, prescribing, adminis-
    tration, licensing, or use of such countermeasure.’’
    (Emphasis added.) 42 U.S.C. § 247d-6d (a) (2) (B) (2018).
    On March 10, 2020, the secretary issued a declaration
    under the PREP Act in response to the COVID-19 pan-
    demic. See Declaration Under the Public Readiness and
    Emergency Preparedness Act for Medical Countermea-
    sures Against COVID-19, 
    85 Fed. Reg. 15,198
     (March
    17, 2020) (PREP Act declaration). Although the PREP
    Act does not define ‘‘administration of covered counter-
    measures,’’ the PREP Act declaration defines that term
    to include both the ‘‘physical provision of the counter-
    measures to recipients’’ and ‘‘activities and decisions
    directly relating to public and private delivery, distribu-
    tion and dispensing of the countermeasures to recipi-
    ents . . . [and] management and operation of
    countermeasure programs . . . .’’ Id., 15,200. The sec-
    retary subsequently amended the PREP Act declaration
    for various purposes. The amended declaration defines
    ‘‘covered countermeasures’’ for COVID-19 to include
    ‘‘[a]ny antiviral, any drug, any biologic, any diagnostic,
    any other device, any respiratory protective device, or
    any vaccine manufactured, used, designed, developed,
    modified, licensed, or procured . . . [t]o diagnose, mit-
    igate, prevent, treat, or cure COVID-19 . . . .’’29 Elev-
    enth Amendment to Declaration Under the Public
    Readiness and Emergency Preparedness Act for Medi-
    cal Countermeasures Against COVID-19, 
    88 Fed. Reg. 30,769
    , 30,774 (May 12, 2023) (amended PREP Act decla-
    ration); see id., 30,774–75 (incorporating PREP Act’s
    definition of ‘‘administration of covered counter-
    measures’’).
    There is no dispute in the present case that the
    COVID-19 diagnostic test administered to the decedent
    on March 21, 2020, constitutes a covered countermea-
    sure for purposes of PREP Act immunity. Nor is there
    any claim that any other covered countermeasure was
    employed. The issue that we must decide is whether
    the decedent’s death was a loss ‘‘caused by, arising out
    of, relating to, or resulting from the administration to
    or the use by an individual’’ of that covered countermea-
    sure under the PREP Act. 42 U.S.C. § 247d-6d (a) (1)
    (2018).
    The construction and application of the PREP Act
    present an issue of statutory interpretation subject to
    plenary review. ‘‘With respect to the construction and
    application of federal statutes, principles of comity and
    consistency require us to follow the plain meaning rule
    . . . . Under the [federal] plain meaning rule, [l]egisla-
    tive history and other tools of interpretation may be
    relied [on] only if the terms of the statute are ambiguous.
    . . . If the text of a statute is ambiguous, then we must
    construct an interpretation consistent with the primary
    purpose of the statute as a whole. . . . Thus, our inter-
    pretive process will begin by inquiring whether the plain
    language of [the] statute, when given its ordinary, com-
    mon meaning . . . is ambiguous. . . . In assessing
    ambiguity, the meaning of the statute must be evaluated
    not only by reference to the language itself but also in
    the specific context in which that language is used, as
    well as in the broader context of the statute as a whole.’’

    Application of the PREP Act to the COVID-19 pan-
    demic has been explored by many federal and state
    courts, and, although most of those decisions are inap-
    posite, a few provide useful guidance in the present
    case. The purpose of the PREP Act, as supplemented by
    the amended PREP Act declaration, was to encourage
    covered providers to implement covered countermea-
    sures as quickly and broadly as reasonably possible
    without fear of liability. See Estate of Maglioli v. Ando-

    an emergency response to the pandemic. Its evident
    purpose is to embolden caregivers, permitting them

    Existing case law also makes it clear that the immu-
    nity conferred by the PREP Act, as it relates to what
    constitutes a covered countermeasure, is narrow in
    scope and far less encompassing than the immunity
    conferred by Executive Order No. 7V. See Estate of

    supra, 
    478 F. Supp. 3d 532

    The PREP Act applies only to the ‘‘administration’’ of
    a covered countermeasure. 42 U.S.C. § 247d-6d (a) (1)

    termeasure’’ is defined broadly to include both the
    ‘‘physical provision of the countermeasures to recipi-
    ents’’ and ‘‘activities and decisions directly relating to
    public and private delivery, distribution, and dispensing
    of the countermeasures to recipients . . . [and] man-

    Order No. 7V, the PREP Act does not apply to all medical

    In particular, and importantly, countermeasures do
    not include protocols or policies designed or imple-
    mented for the prevention or control of COVID-19. See

    A
    We first address the plaintiff’s appeal insofar as it
    challenges the trial court’s dismissal of the claims alleg-
    ing gross negligence, in particular those counts relating
    to acts or omissions prior to receipt of the test results
    on the evening of May 24, 2022. With respect to those
    allegations, the trial court concluded that ‘‘[t]he grava-
    men of the [plaintiff’s] claim is that the defendants
    delayed [the decedent’s] care for a heart attack because
    the defendants mistakenly thought [the decedent] had
    COVID-19. The reason why the defendants thought [the
    decedent] had COVID-19 . . . arose out of and was
    related to the fact that they were awaiting the results of
    a COVID-19 diagnostic test, a covered countermeasure
    under the PREP Act.’’ (Internal quotation marks omit-
    ted.) Accordingly, the trial court concluded that the
    defendants were immune under the PREP Act from
    suit and liability for their conduct, including grossly
    negligent acts or omissions, occurring before receipt
    of the test results. We disagree with the trial court’s
    reasoning and reverse this aspect of its decision.
    The allegations in the complaint control our analysis.
    The plaintiff alleged in her complaint, among other
    things, that the individual defendants were grossly neg-
    ligent in that they (1) ‘‘failed to timely diagnose [the
    decedent] with a myocardial infarction,’’ despite vari-
    ous test results that were indicative of that condition,
    (2) ‘‘failed to immediately transfer [the decedent] to the
    cardiac catheterization lab’’ for treatment and ‘‘caused
    an unreasonable delay in delivering proper care and
    treatment to [the decedent],’’ and (3) ‘‘failed to properly
    monitor [the decedent], and left her alone in her room
    when [they] knew or should have known she was suffer-
    ing from a life-threatening condition.’’ The plaintiff did
    not allege that the decedent’s death was caused by
    the defendants’ improper administration, prescription,
    dispensing, or use of the COVID-19 test. The plaintiff’s
    claim, instead, is that the defendants were grossly negli-
    gent because they failed to diagnose the decedent as
    suffering from a STEMI and because, even if they rea-
    sonably believed that the decedent’s symptoms were
    caused by COVID-19, they failed to admit her immedi-
    ately to the catheterization lab.30 We concluded in part
    I of this opinion that the clinical COVID-19 diagnosis
    and the hospital’s COVID-19 protocol, which resulted
    in the delayed approval for the decedent’s admission
    to the catheterization lab, were subject to the immunity
    provision of Executive Order No. 7V because they were
    undertaken in good faith and in support of the state’s
    COVID-19 response. Neither the COVID-19 diagnosis
    nor the protocol, however, was a covered countermea-
    sure under the PREP Act. See, e.g., Crupi v. Heights
    of Summerlin, LLC, 
    supra,
     
    2022 WL 489857
    , *6;
    Whitehead v. Pine Haven Operating, LLC, 
    supra,
     
    75 Misc. 3d 991
    .
    We recognize that the delay in treatment attendant
    to the COVID-19 test may in fact have had a causal
    relationship to the decedent’s death. Indeed, if the pro-
    cessing of the test had been instantaneous or taken
    little time—a matter beyond the defendants’ control—
    the decedent might well have been admitted to the
    catheterization lab immediately, which may have saved
    her life (or, regardless of the outcome, eliminated the
    claim of malpractice). But the mere fact that the defen-
    dants administered and used a COVID-19 test did not,
    in and of itself, dictate whether they should or should
    not proceed with treatment while the test result was
    pending. That decision was driven by the defendants’
    clinical COVID-19 related diagnosis and the hospital’s
    catheterization lab protocol. There would have been no
    delay attributable to the defendants if they had immedi-
    ately diagnosed her STEMI or, despite suspecting that
    she suffered from COVID-19, had immediately admitted
    her to the catheterization lab while the COVID-19 test
    result was pending, as the plaintiff alleges they should
    have done.31 Thus, as alleged by the plaintiff, the gross
    negligence resulting in the decedent’s demise was not
    causally related to, did not arise out of, and was not
    related to the administration or use of the COVID-19
    test within the meaning of the PREP Act.
    The decision of the federal District Court in Goins
    v. Saint Elizabeth Medical Center, Docket No. 22-91-
    DLB-CJS, 
    2022 WL 17413570
     (E.D. Ky. November 9,
    2022), is instructive on this point. In that case, the plain-
    tiff alleged that she developed certain health issues after
    she received a COVID-19 vaccine. Id., *1. She further
    alleged that, as a result of these health issues, she was
    required to undergo multiple surgeries and other
    courses of treatment, in the course of which several
    of the defendants committed medical malpractice. Id.,
    *1–2. The defendants contended that the plaintiff’s
    claims were preempted by the PREP Act. Id., *4. The
    District Court concluded that PREP Act immunity did
    not apply to the plaintiff’s medical malpractice claims
    arising from the defendants’ alleged negligence after
    she received the COVID-19 vaccine because, although
    the plaintiff alleged that the administration of the vac-
    cine was a cause of her injuries, ‘‘none of her claims
    [against the particular defendants who provided medi-
    cal care to the plaintiff after she received the COVID-19
    test], and most importantly, none of the facts asserted
    alongside her claims, make[s] allegations regarding
    [those defendants’] prescription, administration, or dis-
    pensation of the vaccine.’’32 Id., *8. The District Court’s
    analysis in Goins recognizes that the fact that a covered
    countermeasure may have been a cause of the plaintiff’s
    injuries does not mean that a defendant is entitled to
    immunity under the PREP Act if the plaintiff has alleged
    that the defendant engaged in tortious conduct that
    constituted a distinct and independent cause of the
    plaintiff’s injuries that itself has no causal relationship
    to the countermeasure. Put another way, there is no
    immunity for medical malpractice that does not involve
    the administration or use of a countermeasure, even if
    the countermeasure was employed during the plaintiff’s
    treatment and had a distinct and independent causal
    relationship with the loss. See id. (PREP Act immunity
    did not apply because Goins was ‘‘an ordinary malprac-
    tice suit brought under Kentucky law, by a Kentucky
    plaintiff, against Kentucky defendants’’); see also Estate
    of Maglioli v. Andover Subacute Rehabilitation Center
    I, supra, 
    478 F. Supp. 3d 532
     (PREP Act ‘‘leaves room
    for ordinary claims of negligent or substandard care’’
    relating to diagnosis and treatment of COVID-19); Wil-
    helms v. ProMedica Health System, Inc., 
    205 N.E.3d 1159
    , 1166 (Ohio App.) (mere fact that countermeasure
    was employed during treatment of COVID-19 did not
    mean that plaintiff’s ‘‘loss or injuries [were] caused [by]
    arose out of, related to, or resulted from the administra-
    tion of or the use of the [countermeasure]’’), appeal
    denied, 
    170 Ohio St. 3d 1420
    , 
    208 N.E.3d 855
     (2023).
    The foregoing analysis leads us to conclude that the
    PREP Act does not provide immunity from suit and
    liability for losses arising from the defendants’ treat-
    ment of the decedent before the receipt of the negative
    COVID-19 test result.
    The defendants urge us to reach a contrary result in
    reliance on the decision of the United States District
    Court for the District of New Mexico in Storment v.
    Walgreen, Co., Docket No. 1:21-cv-00898 MIS/CG, 
    2022 WL 2966607
     (D.N.M. July 27, 2022).33 In Storment, the
    plaintiff alleged that she received a COVID-19 vaccina-
    tion at the defendant pharmacy. Id., *1. She became
    dizzy after receiving the vaccine and saw no chairs
    in the pharmacy that would allow her to sit until the
    symptoms passed. Id. She sustained injuries after falling
    as the result of her dizziness. Id. The defendant claimed
    that it was immune from suit and liability for the plain-
    tiff’s injuries under the PREP Act. Id. The District Court
    concluded that, although ‘‘[t]his chain of events [was]
    unfortunate and certainly deserving of a remedy . . .
    it [could not] be divorced from the administration of a
    covered countermeasure—the COVID-19 vaccine [that
    the plaintiff] received.’’ Id., *3. Accordingly, the court
    held that the defendants in Storment were immune from
    suit and liability under the PREP Act. Id.
    Storment is not on point because the plaintiff in that
    case alleged that her injury was attributable to the
    improper administration of a covered countermea-
    sure—a COVID-19 vaccine. See id., *1. As we explained,
    the plaintiff in the present case does not allege that the
    decedent’s death was caused by, arose out of, or was
    related to the improper administration or use of the
    COVID-19 test but claims that the defendants were
    grossly negligent when they failed to diagnose her
    STEMI and to admit her immediately to the catheteriza-
    tion lab. Moreover, application of the immunity con-
    ferred by the PREP Act in Storment advanced the
    purpose of the legislation, namely, to allow medical
    providers to provide COVID-19 vaccines quickly and
    broadly to the public without fear of being held liable
    for any injuries attributable to them. If the plaintiff is
    able to prove her allegations, no comparable policy is
    advanced by the defendants’ conduct in the present
    case.
    B
    We next address the defendants’ appeal challenging
    the trial court’s determination that the PREP Act does
    not provide immunity from the claims against Farrell
    and the hospital involving events after they received
    the decedent’s negative COVID-19 test result. The trial
    court reasoned that receipt of the test result broke the
    connection between the test and the medical treatment
    provided to the decedent after the result became
    known. We concluded in part II A of this opinion that
    the PREP Act does not confer immunity from suit and
    liability for the allegedly negligent conduct of Rizvi,
    Ferraro-Borgida, and Duncan before the receipt of the
    decedent’s negative COVID-19 test result. A fortiori, the
    PREP Act does not provide immunity for the allegedly
    negligent conduct of Farrell and the hospital after
    receipt of the test result. If, as we have concluded, there
    is no allegation of any causal relationship between the
    administration of the COVID-19 test and the plaintiff’s
    allegations of negligence before receipt of the test result
    for purposes of the PREP Act, the receipt of the test
    result could not have created such a connection. Indeed,
    the defendants do not claim otherwise; they claim only
    that the trial court incorrectly determined that the
    receipt of the test result broke the connection between
    the administration of the test and their allegedly negli-
    gent conduct. We therefore uphold the determination
    of the trial court that Farrell and the hospital are not
    immune from suit and liability under the PREP Act for
    their allegedly negligent conduct occurring after receipt
    of the negative COVID-19 test on this alternative ground.
    Finally, we pause to comment on a superficial but
    ultimately illusory tension that may be perceived
    between our analysis under the PREP Act, in which
    the delay associated with the COVID-19 testing of the
    decedent does not trigger any immunity, and our analy-
    sis under Executive Order No. 7V, in which we conclude
    that the defendants are entitled to immunity for the
    period of time before the test result became known.
    The difference in outcome arises because the respective
    immunities are different in scope. Immunity under the
    PREP Act hinges on there being a connection between
    the allegedly tortious conduct and the administration
    or use of a ‘‘covered countermeasure.’’ No such relation-
    ship exists in the present case because the alleged mis-
    diagnosis occurred irrespective of the administration
    or use of the COVID-19 test, the only countermeasure
    at issue. The administration and use of the COVID-19
    test was not tortious. Nor did the ensuing delay cause
    the only alleged tortious conduct, i.e., the misdiagnosis.
    The mere fact that a covered countermeasure was
    administered at some point does not, without more,
    entitle a defendant to immunity under the PREP Act.34
    Immunity under Executive Order No. 7V, by contrast,
    hinges on the existence of a nexus between the alleged
    misdiagnosis and the defendants’ provision of services
    in support of the state’s COVID-19 response. Those ser-
    vices plainly include the defendants’ diagnosis of a
    COVID-19 related condition, regardless of whether that
    diagnosis was, as the plaintiff claims, the result of negli-
    gence. The defendants’ alleged misdiagnosis in the pres-
    ent case was itself the provision of services in support
    of the state’s COVID-19 response, thus triggering the
    immunity for the period of time when that diagnosis
    remained operative.
    In light of our conclusions in parts I and II of this
    opinion, the plaintiff is entitled to proceed on the counts
    alleging gross negligence against all of the defendants
    and the count alleging negligence against Farrell and
    the hospital. The defendants’ arguments as to whether
    the allegations are legally sufficient to support gross
    negligence; see footnote 10 of this opinion; are matters
    properly resolved by the trial court in further pro-
    ceedings.
    The decision of the trial court is reversed in part
    insofar as it dismissed counts V, VI, and VII of the
    complaint and the case is remanded with direction to
    deny the motions to dismiss with respect to those
    counts and for further proceedings according to law;
    the decision of the trial court is affirmed in all other
    respects.
    In this opinion the other justices concurred.
    * August 8, 2023, the date that this decision was released as a slip opinion,
    is the operative date for all substantive and procedural purposes.

    Section 6 of Executive Order No. 7V provides in relevant part: ‘‘Notwith-
    standing any provision of the Connecticut General Statutes or any other
    state law, including the common law, or any associated regulations, rules,
    policies, or procedures, any health care professional or health care facility
    shall be immune from suit for civil liability for any injury or death alleged
    to have been sustained because of the individual’s or health care facility’s
    acts or omissions undertaken in good faith while providing health care
    services in support of the [s]tate’s COVID-19 response, including but not
    limited to acts or omissions undertaken because of a lack of resources,
    attributable to the COVID-19 pandemic, that renders the health care profes-
    sional or health care facility unable to provide the level or manner of care
    that otherwise would have been required in the absence of the COVID-19
    pandemic and which resulted in the damages at issue, provided that nothing
    in this order shall remove or limit any immunity conferred by any provision
    of the Connecticut General Statutes or other law. Such immunity shall not
    extend to acts or omissions that constitute a crime, fraud, malice, gross
    negligence, [wilful] misconduct, or would otherwise constitute a false claim
    or prohibited act pursuant to [§] 4-275 et seq. of the Connecticut General
    Statutes or 31 U.S.C. [§] 3729 et seq. . . . The immunity conferred by this
    order applies to acts or omissions subject to this order occurring at any
    time during the public health and civil preparedness emergency declared
    on March 10, 2020, including any period of extension or renewal, including
    acts or omissions occurring prior to the issuance of this order attributable
    to the COVID-19 response effort.’’
    The executive order defines the terms ‘‘health care professional’’ and
    ‘‘health care facility.’’ See Executive Order No. 7V, § 6 (April 7, 2020). There
    is no dispute in the present case that the defendants fall within these terms.
    2
    Section 247d-6d of title 42 of the 2018 edition of the United States Code
    provides in relevant part: ‘‘(a) Liability protections
    ‘‘(1) In general
    ‘‘Subject to the other provisions of this section, a covered person shall
    be immune from suit and liability under Federal and State law with respect
    to all claims for loss caused by, arising out of, relating to, or resulting from
    the administration to or the use by an individual of a covered countermeasure
    if a declaration under subsection (b) has been issued with respect to
    such countermeasure.
    ‘‘(2) Scope of claims for loss
    ‘‘(A) Loss
    ‘‘For purposes of this section, the term ‘loss’ means any type of loss,
    including—
    ‘‘(i) death;
    ‘‘(ii) physical, mental, or emotional injury, illness, disability, or condition;
    ‘‘(iii) fear of physical, mental, or emotional injury, illness, disability, or
    condition, including any need for medical monitoring; and
    ‘‘(iv) loss of or damage to property, including business interruption loss.
    ‘‘Each of clauses (i) through (iv) applies without regard to the date of
    the occurrence, presentation, or discovery of the loss described in the clause.
    ‘‘(B) Scope
    ‘‘The immunity under paragraph (1) applies to any claim for loss that has
    a causal relationship with the administration to or use by an individual of
    a covered countermeasure, including a causal relationship with the design,
    development, clinical testing or investigation, manufacture, labeling, distri-
    bution, formulation, packaging, marketing, promotion, sale, purchase, dona-
    tion, dispensing, prescribing, administration, licensing, or use of such
    countermeasure.
    ***
    ‘‘(d) Exception to immunity of covered persons
    ‘‘(1) In general
    ‘‘Subject to subsection (f), the sole exception to the immunity from suit
    and liability of covered persons set forth in subsection (a) shall be for an
    exclusive Federal cause of action against a covered person for death or
    serious physical injury proximately caused by willful misconduct, as defined
    pursuant to subsection (c), by such covered person. For purposes of section
    2679 (b) (2) (B) of title 28, such a cause of action is not an action brought
    for violation of a statute of the United States under which an action against
    an individual is otherwise authorized. . . .’’
    3
    Each count of the complaint is brought against one of the defendant
    physicians and the hospital. The hospital is being sued only for its derivative
    liability for the acts of the defendant physicians, its employees or agents
    (i.e., respondeat superior). We refer in this opinion only to the individual
    defendants, unless there is a reason to mention the hospital.
    4
    The plaintiff, the hospital, and Farrell appealed separately to the Appel-
    late Court. We then transferred the appeals to this court pursuant to General
    Statutes § 51-199 (c) and Practice Book § 65-1, and consolidated them.
    5
    The decedent’s medical records also indicate that she told the Backus
    staff that her granddaughter recently had strep throat and that a rapid strep
    test was performed on the decedent. The records do not indicate whether
    the test result was negative, but we presume that to be the case.
    6
    Cardiac catheterization is a procedure used for various interventional
    and diagnostic purposes. The standard procedure for an acute STEMI is a
    ‘‘primary percutaneous coronary intervention,’’ in which a balloon is inserted
    and inflated to remedy blocked blood flow to the heart. See M. Ahmad et
    al., Percutaneous Coronary Intervention (last updated September 30, 2022),
    available at https://www.ncbi.nlm.nih.gov/books/NBK556123/ (last visited

    The defendants neither submitted a written copy of the protocol nor
    quoted the text of the protocol in any of their affidavits. The quotation in the
    body of this opinion accompanying this footnote is taken from a statement
    in the affidavit of Adam Steinberg, the hospital’s vice president for medical
    affairs. That statement is consistent with the description of the protocol in
    the other defendants’ affidavits. There is no indication that the plaintiff
    disputed the existence of this protocol or its contents.

    Troponin is a protein in the blood, which normally ‘‘stays inside [the]
    heart muscle’s cells, but damage to those cells—like the kind of damage
    from a heart attack—causes troponin to leak into [the] blood. Higher levels
    of troponin in [the] blood also mean[s] more heart damage, which can help
    [health care] providers determine the severity of a heart attack.’’ Cleveland

    Counts I though IV alleged negligence respectively against Rizvi, Ferraro-
    Borgida, Duncan, and Farrell. Counts V though VIII alleged gross negligence
    respectively against Rizvi, Ferraro-Borgida, Duncan, and Farrell.
    10
    The defendants also contended that the plaintiff’s claims of gross negli-
    gence should be dismissed because they were simply relabeled negligence
    claims and, therefore, were legally insufficient. The trial court did not address
    this argument.
    11
    The decision dismissing all counts against Rizvi, Borgiga-Ferraro, and
    Duncan is an immediately appealable final judgment. See Practice Book
    § 61-3. The trial court’s denial of the motion to dismiss the counts against
    Farrell (i.e., counts IV and VIII) is not a final judgment but is nonetheless
    immediately appealable under an exception to the final judgment rule for
    a colorable claim of immunity from suit. See, e.g., Miller v. Egan, 
    265 Conn. 301
    , 303 n.2, 
    828 A.2d 549
     (2003) (‘‘[t]he denial of a motion to dismiss based
    on a colorable claim of . . . immunity . . . is an immediately appealable
    final judgment because the order or action so concludes the rights of the
    parties that further proceedings cannot affect them’’ (internal quotation
    marks omitted)).
    12
    The Appellate Court in Prime Management, LLC v. Arthur, supra, 
    217 Conn. App. 737
    , further determined that the plain meaning rule set forth in
    General Statutes § 1-2z applied to its interpretation of an executive order.
    See id., 750–51. We have some doubt about this conclusion, not only because
    § 1-2z on its face applies only to statutes, but also because the judicial
    interpretation of executive orders may involve different considerations than
    those implicated when we interpret legislation. We need not determine in
    the present case, however, whether construction of a clear and unambiguous
    executive order would be subject to the constraints imposed by § 1-2z
    because, for the reasons set forth subsequently in this part of the opinion,
    we conclude that Executive Order No. 7V is ambiguous.
    13
    Although the defendants do not claim that they are immune from suit
    and liability pursuant to the ‘‘lack of resources’’ portion of Executive Order
    No. 7V, we will nevertheless construe both parts of the provision in this
    opinion because we must ensure that nothing in the lack of resources portion
    affects our construction of the first part of the sentence. The immunity is
    set forth as an integrated whole, and its meaning must be understood as
    such. ‘‘We are obligated to search for a construction of the statute that
    makes a harmonious whole of its constituent parts.’’ (Internal quotation
    marks omitted.) Harpaz v. Laidlaw Transit, Inc.,

    executive order is directly at issue in another case that we also decide
    today. See Manginelli v. Regency House of Wallingford, Inc., 
    347 Conn. 581
    , 585,       A.3d      (2023).

    Section 19a-131a authorizes the governor to declare a public health
    emergency. Section 28-9 (a) authorizes the governor to declare a civil pre-
    paredness emergency, and § 28-9 (b) further provides in relevant part: ‘‘(1)
    Following the Governor’s proclamation of a civil preparedness emergency
    pursuant to subsection (a) of this section or declaration of a public health
    emergency pursuant to section 19a-131a, the Governor may modify or sus-
    pend in whole or in part, by order as hereinafter provided, any statute,
    regulation or requirement or part thereof whenever the Governor finds such
    statute, regulation or requirement, or part thereof, is in conflict with the
    efficient and expeditious execution of civil preparedness functions or the
    protection of the public health. The Governor shall specify in such order
    the reason or reasons therefor and any statute, regulation or requirement
    or part thereof to be modified or suspended and the period, not exceeding
    six months unless sooner revoked, during which such order shall be
    enforced. . . .

    ‘‘(7) The Governor may take such other steps as are reasonably necessary

    Executive Order No. 7U contains an immunity provision, § 1, that is
    identical to the one issued two days later in § 6 of Executive Order No. 7V,
    except that the latter provision adds language stating that the immunity
    applies notwithstanding ‘‘any other state law, including the common law
    . . . .’’ (Emphasis added.) Executive Order No. 7V (April 7, 2020). Section
    6 of Executive Order No. 7V superseded § 1 of Executive Order No. 7U, but
    Executive Order No. 7V expressly states that the findings in Executive Order
    No. 7U retain their effect, as do the remaining provisions. See id. The findings
    in Executive Order No. 7V are entirely consistent with those in Executive
    Order No. 7U.

    Prevention of COVID-19 could apply to measures directed at protecting
    an individual, as well as those directed to society generally or a class of indi-
    viduals.
    18
    We recognize that the plaintiff brought the present lawsuit pursuant to
    the wrongful death statute, § 52-555. Putting aside the question of whether
    the plaintiffs’ negligence claims would be characterized as purely statutory or
    common law in derivation; see Soto v. Bushmaster Firearms International,
    LLC, 
    331 Conn. 53
    , 104–105, 
    202 A.3d 262

    140 S. Ct. 513
    , 
    205 L. Ed. 2d 317
     (2019);
    Executive Order No. 7V, § 6, explicitly applies to both common-law and
    statutory claims, and we will not assume that the scope of the immunity
    was intended to shrink or expand depending on whether the plaintiff is
    asserting a common-law or statutory claim.
    19
    A similar concern would arise under § 28-9 (b) (1), which authorizes
    the governor only to modify and suspend laws, regulations or requirements
    that are ‘‘in conflict with the efficient and expeditious execution of civil
    preparedness functions or the protection of the public health.’’ A different
    constitutional concern would arise if an executive order exceeded the limits
    of the authority conferred by § 28-9 (b)—an unconstitutional usurpation of
    legislative authority. See, e.g., Youngstown Sheet & Tube Co. v. Sawyer, 
    343 U.S. 579
    , 588–89, 
    72 S. Ct. 863
    , 
    96 L. Ed. 1153
     (1952); see also, e.g., Bayshore
    Enterprises, Inc. v. Murphy, Docket Nos. A-3616-19 and A-3873-19, 
    2021 WL 3120868
    , *9 (N.J. Super. App. Div. July 23, 2021) (acknowledging that
    executive order issued in response to COVID-19 pandemic under New Jer-
    sey’s Emergency Health Powers Act would be ‘‘invalid if it usurps legislative
    authority by acting contrary to the express or implied will of the [l]egislature’’
    (internal quotation marks omitted)).
    20
    In part I C of this opinion, we mention other potential concerns regarding
    the sweep of immunity provided by Executive Order No. 7V.
    21
    The plaintiff claims that, if she is not entitled on the present record to
    reversal of that portion of the trial court’s decision against her, we should
    remand the case for an evidentiary hearing on the issue of whether the
    defendants’ misdiagnosis was objectively reasonable. The plaintiff has not
    directed this court’s attention to anywhere in the record where she made
    such a request to the trial court. In any event, we reject the request in light
    of our conclusion that immunity does not depend on whether the defendants’
    misdiagnosis was objectively reasonable.
    22
    In her brief in the defendants’ appeals, the plaintiff vigorously denies
    that the record establishes that the defendants could not reasonably have
    been expected to do anything more than they did after the receipt of the
    negative COVID-19 test result to prevent the decedent’s death. We need not
    resolve this question because the dispute relates to liability, not immunity.
    23
    Farrell’s contention that his treatment plan for the decedent, after receipt
    of the test results, was a reasonable one given the long passage of time
    since she initially suffered an acute cardiac event goes to the question of
    liability, not immunity; so, too, does his contention that his treatment plan
    for the decedent conformed to the one endorsed by the other defendant phy-
    sicians.
    24
    In response to the plaintiff’s assertion that the defendants could have
    ordered an echocardiogram after receipt of the negative COVID-19 test
    result, the hospital claims that the defendants could not have done so
    because its COVID-19 protocol precluded that procedure in the absence of
    an ‘‘absolute clinical need . . . .’’ (Emphasis omitted; internal quotation
    marks omitted.) The record does not establish conclusively either that an
    echocardiogram was the only reasonably possible treatment for the dece-
    dent’s condition at that time or that she did not have an absolute clinical
    need for one. The hospital also suggests that the defendants were required
    to assume that the decedent suffered from COVID-19, even after receipt of
    the negative test result. It is undisputed that all of the physicians who treated
    the decedent contemplated that her treatment plan would change if she
    tested negative for COVID-19, presumably because they believed that a
    negative result would indicate that COVID-19 was not the cause of her
    symptoms.
    25
    The plaintiff did raise a claim in the trial court that affording immunity
    to the defendants in the present case would violate the open courts provision
    of the state constitution. See Conn. Const., art. I, § 10. The trial court con-
    cluded that this provision was inapplicable because the plaintiff’s claims
    were brought pursuant to the wrongful death statute, § 52-555, and the
    plaintiff did not challenge that determination on appeal.
    26
    This court invited amici curiae to file briefs in the present case and a
    related case, Manginelli v. Regency House of Wallingford, Inc., 
    347 Conn. 581
    ,         A.3d     (2023); see footnote 13 of this opinion; to address the
    following questions, on which the parties were ordered to submit supplemen-
    tal briefs:
    ‘‘1. Does this case present an exceptional circumstance for this court to
    invoke its authority under [Blumberg Associates Worldwide, Inc. v. Brown &
    Brown of Connecticut, Inc.], 
    311 Conn. 123
    , 
    84 A.3d 840
     (2014), to raise and
    decide the issues identified below, which were not addressed by the parties?
    ‘‘2. If the answer to the first question is ‘yes,’ does the governor have the
    authority under . . . § 28-9 (b) (1) or (7) and/or Casey v. Lamont, [supra,
    
    338 Conn. 479
    ], to suspend the common law?
    ‘‘3. If the answer to the second question is ‘no,’ what was the source of
    the governor’s authority to enact [§] 6 of Executive Order [No.] 7V?
    ‘‘4. Under . . . § 28-9 (b) (1) or (7) and/or Casey . . . does the governor
    have the authority to create and confer immunity through an executive
    order?’’
    27
    The immunity conferred by Executive Order No. 7V does not cover
    gross negligence. See Executive Order No. 7V, § 6 (April 7, 2000).
    28
    There is no claim in the present case that the defendant physicians are
    not covered persons under the PREP Act. See 42 U.S.C. § 247d-6d (i) (2)
    (B) (iv) (2018) (defining ‘‘covered person’’ to include ‘‘a qualified person
    who prescribed, administered, or dispensed such countermeasure’’); 
    42 U.S.C. § 247
    -6d (i) (8) (A) (2018) (defining ‘‘qualified person’’ to include ‘‘a
    licensed health professional or other individual who is authorized to pre-
    scribe, administer, or dispense such countermeasures under the law of the
    State in which the countermeasure was prescribed, administered, or dis-
    pensed’’).
    29
    The liability protections provided by the amended PREP Act declaration
    are retroactive to March 10, 2020, the date that Governor Lamont declared
    a public health emergency. See Eleventh Amendment to Declaration Under
    the Public Readiness and Emergency Preparedness Act for Medical Counter-
    measures Against COVID-19, supra, 
    88 Fed. Reg. 30,775
    .
    30
    The plaintiff did not specifically allege in her complaint that the defen-
    dants were grossly negligent when they failed to admit the decedent immedi-
    ately to the catheterization lab, even if they reasonably believed that her
    symptoms were being caused by COVID-19, because she did not preemp-
    tively anticipate the defendants’ immunity defense. We must read the com-
    plaint broadly in her favor, however, and we cannot conclude at this stage
    of the proceedings that she would be precluded from attempting to establish
    at trial that the standard of care requires immediate admission to the cathe-
    terization lab of any patient who presents with STEMI symptoms, even if
    some other cause is suspected, in light of the severe consequences of a
    delay in a definitive diagnosis.
    31
    Although not directly on point, the decision of the federal District Court
    in Haro v. Kaiser Foundation Hospitals, Docket No. CV 20-6006-GW-JCx,
    
    2020 WL 5291014
     (C.D. Cal. September 3, 2020), is instructive. In Haro, the
    plaintiff claimed that the defendant had required its hourly employees to
    arrive at least fifteen minutes before the start of their work shift so that
    they could undergo screening for COVID-19. Id., *1. The plaintiff sought
    compensation for this time. Id. The defendant contended that it was immune
    from suit and liability for this claim under the PREP Act. Id. The court
    concluded that the plaintiff’s wage claim was ‘‘not causally connected to the
    screening procedures themselves, but rather the requirement that employees
    show up [fifteen] minutes before their shifts start. [The defendant] could
    just as easily have implemented the screenings without the requirement that
    employees show up early. In that case, the screening procedures would
    simply have occurred while employees were on the clock and [the plaintiff]
    would not have a [minimum wage] claim.’’ (Emphasis omitted.) Id., *3.
    Similarly, in the present case, if the defendants had diagnosed the decedent
    with a suspected STEMI and admitted her to the catheterization lab while
    the COVID-19 test results were pending (as the plaintiff’s complaint, read
    broadly in her favor, alleges they should have done), the pending COVID-19
    test would have had no impact on the care that they provided to the decedent.
    32
    The specific issue addressed by the court in Goins was whether the
    defendants who treated the plaintiff in that case after she received the
    vaccine were ‘‘covered persons’’ for purposes of the PREP Act. See Goins
    v. Saint Elizabeth Medical Center, supra, 
    2022 WL 17413570
    , *7–8. The court
    concluded that they were not because the plaintiff made no allegation that
    they prescribed, administered or dispensed the COVID-19 vaccine. See id.;
    see also 42 U.S.C. § 247d-6d (i) (2) (B) (iv) (2018) (defining ‘‘covered person’’
    to include ‘‘a qualified person who prescribed, administered, or dispensed
    such countermeasure’’). As framed by the plaintiff in the present case, the
    issue is not whether the defendants are covered persons, but whether the
    complaint alleges that the death has a causal relationship with the adminis-
    tration to or use by an individual of a covered countermeasure. Accordingly,
    we do not address the question of whether any or all of the defendants
    were covered persons under the PREP Act. The Goins analysis nonetheless
    supports the plaintiff’s position here because of the overlapping analyses
    of these issues under the language of the statute.
    33
    The defendants also cite a number of cases that do not involve the
    PREP Act for the proposition that the phrase ‘‘arising out of,’’ as used in
    the PREP Act; 42 U.S.C. § 247d-6d (a) (1) (2018); should be interpreted
    broadly. See Ford Motor Co. v. Montana Eighth Judicial District Court,
    U.S.     , 
    141 S. Ct. 1017
    , 1026, 
    209 L. Ed. 2d 225
     (2021) (construing
    phrase ‘‘arise out of or relate to the defendant’s contacts with the forum,’’
    as used in court’s personal jurisdiction jurisprudence (emphasis omitted;
    internal quotation marks omitted)); United States v. Shearer, 
    473 U.S. 52
    ,
    54–55, 
    105 S. Ct. 3039
    , 
    87 L. Ed. 2d 38
     (1985) (construing phrase ‘‘[a]ny claim
    arising out of assault [or] battery,’’ as used in portion of Federal Tort Claims
    Act, as excepting such claims from waiver of sovereign immunity (internal
    quotation marks omitted)); Nationwide Mutual Ins. Co. v. Pasiak, 
    327 Conn. 225
    , 242–54, 
    173 A.3d 888
     (2017) (construing phrase ‘‘arising out of,’’ as used
    in insurance policies). These cases provide minimal guidance because they
    do not involve the PREP Act. In our view the plaintiff’s claims do not ‘‘arise
    out of’’ the administration of the COVID-19 test to the decedent, regardless
    of the breadth of that term.
    34
    To illustrate this point, assume hypothetically that the COVID-19 test
    had been administered at Backus, before the defendants’ involvement, but
    the result thereafter was relayed to the defendants. In this scenario, the
    defendants would not be immune under the PREP Act because their alleged
    negligence—their misdiagnosis of a COVID-19 related condition—has no
    causal relationship to the COVID-19 test performed earlier by some other
    caregiver. By contrast, the defendants would be immune under Executive
    Order No. 7V, until the test result came back, because the alleged malpractice
    occurred in connection with diagnostic services provided by the defendants
    in support of the state’s response to COVID-19.
