Official title
Study of the Incidence of SARS-CoV-2 Infection in the Alpes-Maritimes Department by Analysis of the Specific Humoral and Cellular Response During Deconfinement
Overview
This is a prospective observational cohort study that will define the prevalence and incidence of CA-SARS-Cov2 infection using serological and PCR tests in a group of subjects during deconfinement. The team wishes to include approximately 1000 subjects in this study. The health crisis through containment has also created unprecedented environmental conditions with the very clear decrease in economic activities and a consequent decrease in exposure to the main air pollutants. The aim is therefore to carry out a case-control study in which each subject will be his or her own control in unexposed condition (to PM2.5, PM10, NO...) then exposed (after the recovery of economic activity and the usual levels of air pollutants) and to measure the impact of these pollutants on the immune system and epigenetic markers taking into account seasonality. The occurrence of infectious, cardiovascular, allergic and autoimmune events will then be measured according to the immunological profiles measured at inclusion.
