This study was designed to determine, in a screening situation within the framework of university preventive medicine, the prevalence of positive anti-SARS-Cov 2 serology among the staff of the University of Reims Champagne-Ardenne. The serological tests chosen will allow systematic detection of anti-SARS-CoV-2 IgM and anti-SARS-Cov-2 IgG to assess the moment of potential contamination prior to resumption of occupational activity.
