Summary
This study aims to quantify and follow the cumulative incidence of SARS-CoV-2 infection in the French population using serological tests and to assess the determinants of infection from Constances, E3N-E4N, ELFE-Epipage 2 and NutriNet-Santé cohorts.
Detailed description
The primary objective is to assess the cumulative incidence of infection in the general population using dried blood spot sampling. The secondary objectives are: * To identify factors associated with a positive SARS-CoV-2 infection (positive serology) and to characterize the durability of the serological response to SARS-CoV-2 * To identify associations of symptoms predictive of a SARS-CoV-2 infection * To estimate the health care use associated with a SARS-CoV-2 infection * To estimate the fraction of sub-clinical infections or infections not captured by the healthcare system; * To study the acceptability of a mass anti-SARS-CoV-2 serological testing and the impact of its result, linked with social inequalities in health; * To estimate the individual and collective impact of containment and other preventive measures on the risk of SARS-CoV-2 infection; * To study the impact of social and territorial inequalities on seroprevalence levels.
