Since the beginning of the pandemic, all patients diagnosed with COVID-19 have received a call from the Department of Preventive Medicine of Fattouma Bourguiba university hospital one day after the diagnosis is confirmed, to identify individuals who may have been in close contact with them (Contact tracing). In addition to the usual contact tracing, the intervention group received a telephone health education session on the first day of confirmation of the diagnosis. Calls were delivered by medical residents who were trained in communication skills and on intervention delivery prior to initiation of the study. Each call lasted approximately 10 to 15 min. The educators targeted three axes of messages: (Axe 1) Explanation of the Coronavirus disease, (Axe 2) Self-monitoring and what to do in case of complications, (Axe 3) Preventive measures to respect (Box
