No Intervention: Active surveillance



Primary Outcome Measures :
  1. 21-day incidence of COVID-19 in individuals exposed to SARS-CoV- 2 who are asymptomatic at baseline (intent-to-treat (ITT) analysis). [ Time Frame: 21-day ]

Secondary Outcome Measures :
  1. 21-day incidence of COVID-19 in individuals exposed to SARS-CoV- 2 who are asymptomatic, PCR-confirmed SARS-CoV-2 negative and have negative SARS-CoV-2 serology at baseline (modified ITT) [ Time Frame: 21-day ]
  2. 21-day incidence of SARS-CoV-2 infection in individuals exposed to SARS-CoV-2 who are asymptomatic, PCR-confirmed SARS-CoV-2 negative and have negative SARS-CoV-2 serology at baseline (modified ITT) [ Time Frame: 21-day ]
  3. Severity of clinical COVID-19 on a 7-point ordinal scale [ Time Frame: 21-day ]
    (1: not hospitalized, no limitations on activities, 2: not hospitalized, limitation on activities, 3: hospitalized, not requiring supplemental oxygen, 4: hospitalized, requiring supplemental oxygen, 5: hospitalized, on non- invasive mechanical ventilation 6: hospitalized, on invasive mechanical ventilation or ECMO and 7: death)
