Brief summary
The objectives of PROVIDE are to: 1. Determine if prophylactic once weekly hydroxychloroquine reduces the incidence of conversion from SARS-2-CoVnasopharyngeal swab negative to positive 2. To determine if weekly prophylactic hydroxychloroquine reduced the severity of COVID-19 symptoms 3. To determine the safety of taking weekly prophylactic hydroxychloroquine
Interventions
Hydroxychloroquine sulfate 400mg PO BID on day one, then 400mg PO weekly, to be taken with meals for two months total.
