Brief Summary

The aim of the study is to determine the incidence o of SARS-cov2 infection among health care workers highly exposed to covid 19 during 10 weeks et to analyze the determinants of their occupational and environmental exposure. Every 14 days, we performed SARS-Cov2 RT- PCR, serological testing and clinical questionnaire among a cohort of 100 HCW with a high degree of exposure to covid19 infection. Information about occupational exposure as the workplace, the activity of care, the characteristics of patient infected are captured, as well as environmental or personal exposure. The results will support the design of a new care organization and will define new ways of protection for patients (covid or not covid 19) and prevention for HCW.
