Source: Own elaboration based on data from Santé publique France, INSEE. This document mirrors screening programs with the treatment of patients in hospitals. From (A) to (D), the entire treatment chain appears implicitly, following the reductionist model described in Fig. 3. The number of people concerned decreases from one map to the next one. The closest approximation to a general prevalence rate is in (B). This map is the most important one because it shows the virus spread in its ‘native’ form, e.g. outside hospital channels. Data collection started at different times for database 1 and database 2. Statistical consistency increases over the first weeks of March as the reporting system gains momentum
SARS-CoV-2 dissemination patterns by department, March 10-May 26, stringent lockdown period.
