Eligibility criteria:

        Inclusion Criteria:

          1. Has COVID-19 disease, defined by having one or more of the following new symptoms and
             signs (within 7 days):

               -  Fevers OR

               -  At least one of the following symptoms: cough, shortness of breath, respiratory
                  rate ≥ 20, radiographic evidence of pneumonia OR

               -  Anosmia OR

               -  other clinical symptoms or signs of COVID-19 that are not otherwise explained by
                  comorbidities or co-diagnoses

          2. PCR+ test for SARS-CoV-2.

          3. Has new signs or symptoms of COVID-19 that began ≤7 days of anticipated first dose of
             study drug.

          4. Persons ≥18 years old.

          5. at the time of first dose.

        5. ≥18 years old.

        6. Is willing and able to comply with all study procedures including providing informed
        consent, collection of virology samples, and any safety tests that are not included as part
        of standard of care (SOC).

        7. Is willing and able to take oral medications, and is anticipated to be able to take the
        full course of 5 days of study drug.

        Pregnancy and Contraception: In nonclinical developmental and reproductive toxicity
        studies, developmental toxicity including malformation was observed in fetuses from
        pregnant animals dosed with EIDD-2801 (MK 4482). Therefore, treatment with EIDD-2801 is
        contraindicated in women who are pregnant or nursing and in the male partners of women who
        are pregnant. Extreme care must be taken to avoid pregnancy during the study and for 4 days
        after completion of EIDD 2801 dosing in female participants and for 4 days after completion
        of EIDD-2801 dosing in female partners of male participants.

        8. A female participant is eligible to participate if she is not pregnant or breastfeeding
        and at least one of the following conditions applies:

          -  Is not a woman of childbearing potential (WOCBP) OR

          -  Is a WOCBP and using a contraceptive method that is highly effective (a low user
             dependency method OR a user-dependent method in combination with a barrier method), or
             be abstinent from heterosexual intercourse as their preferred and usual lifestyle
             (abstinent on a long-term and persistent basis), as described in Appendix 2 during the
             intervention period and for at least 4 days after the last dose of study intervention.
             The investigator should evaluate the potential for contraceptive method failure (ie,
             noncompliance, recently initiated) in relationship to the first dose of study
             intervention.

          -  A WOCBP must have a negative highly sensitive pregnancy test (serum test is required)
             within 24 hours before the first dose of study intervention.

          -  Additional requirements for pregnancy testing during and after study intervention are
             located in Section 4.4.

          -  The investigator is responsible for review of medical history, menstrual history, and
             recent sexual activity to decrease the risk for inclusion of a woman with an early
             undetected pregnancy.

          -  Contraceptive use by women should be consistent with local regulations regarding the
             methods of contraception for those participating in clinical studies.

          -  Given the elevated risk of venous thrombotic events in patients hospitalized with
             COVID 19 (Benson et al 2020; Spratt et al 2020), estrogen-containing contraceptives
             must not be started to fulfill the contraceptive requirement of this study at any time
             during participant's hospitalization. If contraceptives are interrupted as standard of
             care management of COVID-19 patients and resumed at a later time point, such as at
             hospital discharge, then abstinence must be practiced for the defined period of
             back-up contraception per the contraceptive product labeling. After this period,
             contraceptive use must adhere to Appendix 2.

             9. Male participants are eligible to participate if they agree to the following during
             the intervention period and for at least 4 days after the last dose of study
             intervention:

          -  Be abstinent from heterosexual intercourse as their preferred and usual lifestyle
             (abstinent on a long term and persistent basis) and agree to remain abstinent OR

          -  Must agree to use contraception unless confirmed to be azoospermic (vasectomized or
             secondary to medical cause [Appendix 2]) as detailed below:

        Agree to use a male condom plus partner use of an additional contraceptive method when
        having penile-vaginal intercourse with a WOCBP who is not currently pregnant. Note: Men
        with a pregnant or breastfeeding partner must agree to remain abstinent from penile-vaginal
        intercourse or use a male condom during each episode of penile-vaginal penetration.

        • Contraceptive use by men should be consistent with local regulations regarding the
        methods of contraception for those participating in clinical studies.
