Experimental: Pre-exposure prophylaxis of SARS-CoV-2
Participants will receive hydroxychloroquine 400 mg daily during the first 4 days, followed by 400 mg weekly during 6 months
Hydroxychloroquine with the following dosage:
Placebo Comparator: Control group with placebo
Participants will receive placebo 400 mg daily during the first 4 days, followed by 400 mg weekly during 6 months
Placebo with the following dosage:
- Confirmed cases of a COVID-19 [ Time Frame: Up to 6 months after start of treatment ]Confirmed cases of a COVID-19 (defined by a positive PCR for SARS-CoV-2 or symptoms compatible with COVID-19 with seroconversion) in the PrEP group compared to the placebo group at any time during the 6 months of the follow-up in healthcare workers with negative PCR for SARS-CoV-2 on day 0 and negative serology for SARS-CoV-2 on day 0.
- SARS-CoV-2 seroconversion [ Time Frame: Up to 6 months after start of treatment ]SARS-CoV-2 seroconversion in the PrEP group compared to placebo in during 6 months of follow-up in healthcare workers with negative serology at day 0.
- Occurrence of any adverse event related with hydroxychloroquine treatment [ Time Frame: Up to 6 months after start of treatment ]Incidence of clinical and/or laboratory adverse events will be compared in the PrEP group and in the placebo arm.
- Incidence of SARS-CoV-2 infection and COVID-19 among healthcare workers [ Time Frame: Up to 6 months after start of treatment ]Incidence of SARS-CoV-2 infection and COVID-19 among healthcare workers will be estimated by the number of healthcare workers diagnosed with COVID-19 in the placebo group, among the total of healthcare workers included in the non-PrEP group during the study period.
- Risk ratio for the different clinical, analytical and microbiological conditions to develop COVID-19 [ Time Frame: Up to 6 months after start of treatment ]
- COVID-19 Biobank [ Time Frame: Up to 6 months after start of treatment ]A repository (biobank) of serum samples obtained from healthcare workers confirmed COVID-19 cases for future research on blood markers to predict SARS-CoV-2 infection.
