COVID-19: regional results from matching between SI-VIC, SI-DEP and VAC-SI

As part of its mission to support the management of the health crisis, the Directorate of Research, Studies, Evaluation and Statistics (DREES) uses pseudonymised data from the three main databases on the COVID-19 crisis: SI-VIC (hospitalisation), SI-DEP (screening) and VAC-SI (vaccination). These farms lead to numerous analyses, published or used by crisis management actors, on the three themes: screening, hospitalisation and vaccination. DREES also makes crossroads between these bases, in order to shed light on issues that fall within several of these themes jointly. Thus, regular monitoring according to the vaccination status of the number of positive cases in Covid-19 tests and hospital admissions is carried out. Similarly, comparative analyses of the frequency of severe Covid-19 cases depending on the variant or identified mutations of the virus affecting patients may be conducted. These data concern all ages and France as a whole
