Brief Summary: Study Objective: To test if post-exposure prophylaxis with hydroxychloroquine can prevent progression development of symptomatic COVID19 disease after known exposure to the SARS-CoV2 virus.
Detailed Description:

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a rapidly emerging viral infection causing COVID19. The current strategy uses a public health model of identifying infected cases, isolation, and quarantine to stop transmission. Once exposed, observation is standard-of-care.

No effective therapy currently exists for treatment. The lack of effective therapy diminishes persons presenting post-exposure for self-quarantine. Having an effective post-exposure prophylaxis, even if only partially effective, may additionally create synergy for the public health strategy of case identification and isolation - if a safe prophylaxis is available. People who develop COVID-19 disease generally develop signs and symptoms, including mild respiratory symptoms and fever, after an average of 5-6 days after exposure (i.e. mean incubation period). The range of the incubation period is between 1 to 14 days.

Most people infected with the COVID-19 virus have mild disease and recover. Approximately 80% of laboratory-confirmed patients have had mild to moderate disease, which includes non-pneumonia and pneumonia cases, 14% have severe disease, and 6% are critically ill with respiratory failure, shock, and/or multiple organ dysfunction.

Chloroquine or Hydroxychloroquine may have antiviral effects against SARS-COV2 which may prevent COVID19 disease or early preemptive therapy may ameliorate disease severity. This trial will use a modification of standard malaria dosing of hydroxychloroquine to provide post-exposure prophylaxis / preemptive therapy.

The trial is open to enrollment of healthcare workers or household contacts from across the United States. For information on how to participate in the research trial, please email covid19@umn.edu for instructions.

Open or close this module Outcome Measures
Primary Outcome Measures:
1. Incidence of COVID19 Disease
[ Time Frame: 14 days ]

Number of participants at 14 days post enrollment with active COVID19 disease.
2. Ordinal Scale of COVID19 Disease Severity
[ Time Frame: 14 days ]

Participants will self-report disease severity status as one of the following 3 options; no COVID19 illness (score of 1), COVID19 illness with no hospitalization (score of 2), or COVID19 illness with hospitalization or death (score of 3). Increased scale score indicates greater disease severity. Outcome is reported as the percent of participants who fall into each category per arm.
Secondary Outcome Measures:
1. Incidence of Hospitalization
[ Time Frame: 14 days ]

Outcome reported as the number of participants in each arm who require hospitalization for COVID19-related disease.
2. Incidence of Death
[ Time Frame: 90 days ]

Outcome reported as the number of participants in each arm who expire due to COVID-19-related disease.
3. Incidence of Confirmed SARS-CoV-2 Detection
[ Time Frame: 14 days ]

Outcome reported as the number of participants in each arm who have confirmed SARS-CoV-2 infection.
4. Incidence of Symptoms Compatible with COVID19 (possible disease)
[ Time Frame: 90 days ]

Outcome reported as the number of participants in each arm who self-report symptoms compatible with COVID19 infection.
5. Incidence of All-Cause Study Medicine Discontinuation or Withdrawal
[ Time Frame: 14 days ]

Outcome reported as the number of participants in each arm who discontinue or withdraw medication use for any reason.
