Outcome Measures

Primary Outcomes (1)

  • SARS-CoV-2 detection

    The outcome of interest for the primary analysis will be the SARS-CoV-2 detection from study participants who present to the ER ("ER visit") or are hospitalized with SARI, as determined through the standard of care diagnostic testing (i.e., antigen test or PCR).

    Specimen collected between d-14 and d0, where d0 is the day at ER visit or hospital admission (or specimen collected within 24 hours upon arrival at the hospital)

Secondary Outcomes (1)

  • Level of disease severity

    - The Time Frame will be defined as the time from ER/Hospital admission to the date of hospital discharge or date of death at hospital

Study Arms (2)

Case group

Test-positive cases are study participants that meet the SARI case definition AND test positive for at least one SARS-CoV-2 diagnostic test, with specimens collected up to 14 days prior to ER visit or hospitalization or up to 24 hours thereafter

Control group

Test-negative controls are study participants that meet the SARI case definition AND test negative for all SARS-CoV-2 diagnostic test with specimens collected up to 14 days prior to ER visit or hospitalization or up to 24 hours thereafter
