About this study
Official title: Spread Analysis of COVID-19 Outbreak in France by Self-assessment Web-application: an Observational Study
A coronavirus pandemic began on 12/31/2019 with a first Chinese patient. As of 04/04/2020, the epidemic affects more than 190 countries with more than 50 million official contaminations and 1,251,000 deaths. (Univ J Hopkins). This virus causes a pathology ranging from simple flu-like symptoms in 80% of cases to acute respiratory distress syndromes requiring intensive care in 5% of cases and a death rate of 1.4 to 4% of cases.
Viral contamination is airborne and fecal A first epidemic wave crossed France in March / April 2020 then a second in October / November with a source of contamination which began in mid-August 2020. The sources of propagation are not well known (what places, what times, what contacts…? ) In the context of the health crisis linked to the coronavirus, knowledge of the sources of propagation of this 2nd wave is an important issue to guide end of lockdown and second lockdown policies.

What does the primary outcome measure?
