Evaluation of the Prevalence of SARS-CoV-2 Infection in the Healthcare Workers (HCWs) in Four Hospital of the Alpine Region

In France during the first wave of the pandemic, 30,230 symptomatic healthcare workers had been reported positive. Yet, the prevalence of the infection in French healthcare workers remains unknown as it mostly reflect symptomatic infections.

Also, the prevalence of infection was reported being higher in male healthcare workers, and in those having patients' facing roles. However, the impact of the level of exposure to SARS-CoV-2, the use of personal protective equipment and hospital organization to prevent infection and spread remains unclear.

Our study aims to report the seroprevalence of SARS-CoV-2 infection among French healthcare workers after the first wave of the pandemic. It also aims to explore the impact of the type of occupations and the level of exposure to the viruses on the seroprevalence of infection.
