EpiCov is a population-based cohort which aims to provide national and regional estimates of seroprevalence of SARS-CoV-2 infection and analyse relations between living conditions and the dynamics of the epidemic in France. The study population is a random sample of individuals aged 15 years and older, excluding people living in residences for the elderly and living in jail. The participants are recruited from the French national tax register and is representative of the population living in France. Home self-samples on Dried Blood Spots (DBS) for IgG and neutralizing antibodies detection were offered to a random national sub-sample of 12,114 in the 1st round of the EPICOV survey (May 2020) and to all respondents in the 2nd round (November 2020), including also serological testing for all members (≥ 6 years old) of household for 20% of index participants. A third round was perfomed in June-July 2021, without serological measurements. Overall, 134,391 participants have been enrolled in first-round (May 2020). Among them, 107 759 participated to the second round (November 2020) and 85 074 in third round (June 2021). The next wave is expected in March-april 2022.
