Placebo Comparator
Arm Label
Pre-exposure prophylaxis of SARS-CoV-2
Control group with placebo
Arm Description

Outcomes
Primary Outcome Measures
Confirmed cases of a COVID-19
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.
Secondary Outcome Measures
SARS-CoV-2 seroconversion
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
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
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
COVID-19 Biobank
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.
