Study Stopped
Difficulties in recruiting subjects were observed soon after the study was initiated. This difficulty was attributed to the decreased incidence of infections which occurred in the period following the first lock down.

Brief Summary
This is a Italian, superiority, open label cluster-randomised, interventional clinical trial aimed at assessing whether the treatment with Hydroxychloroquine can reduce the percentage of symptomatic subjects compared to observation only in household members/contacts of COVID-19 patients (Group 1) and if the treatment with Hydroxychloroquine could be introduced in early phase COVID-19 population (Group 2). The participants will be randomised to receive either: Arm A) hydroxychloroquine vs Arm B) Observation (2:1 randomisation).
