Brief summary

Given the urgency of having guidelines for the management of COVID-19 in the current epidemic context and the lack of specific pharmacological treatment, Military Health recommends the launch of a multicenter, randomized, double-blind, interventional clinical trial. The aim of this study is to evaluate the efficacy of a combination of two treatments, low-dose doxcycline (100 mg/day) and Zinc (15 mg/day) (dietary supplement) in the primary prevention of COVID-19 infection in health care professionals in Tunisia compared to two control groups.
