France and in particular the paris area was one of the countries most affected by the pandemic Covid19. School closures and a generalized lockdown of the population were instituted in France from 17 March 2020 to 10 May 2020. Schools and nurseries have reopened partially since 11 May 2020. From 2 June, this reopening is more widespread. By combining the search for SARS-Cov2 viruses by PCR and micro-method serology we will be able to evaluate both the infection at a given time and also older contact with SARS-CoV2. The temporal knowledge of the prevalence of SARS-Cov2 carriage and the serological status (IgM and IgG) after return to the community are crucial information to evaluate the speed of spread of the virus in children. This is the objective of COVILLE2, phase 2 of the COVILLE study.
