How does the incidence rate evolve in each department in Île-de-France? The most densely populated region in France, aka Île-de-France, has been very seriously hit by the first and then the second Covid-19 epidemic wave.
Therefore, the government and health authorities rely on very specific criteria to know how virulent the virus is in each department in France: the incidence rate in people including all age ranges, and the incidence rate in elderly people, the most vulnerable faced with Covid-19.
If the rate exceeds the threshold set at 200 cases for 100,000 inhabitants by the government, curfew has been then extended in the area. This Sunday 16 January 2022, the incidence rate is around 2,989.90 in France. In Île-de-France, the same rate goes beyond the threshold set by the government and reaches 3,683.50 . All Île-de-France departments have exceeded the threshold set by the government and the health authorities
Furthermore, Santé publique France says that this incidence rate represents the number of people – in one week – who tested positive (RT-PCR and antigenic tests included) for the first since in over 60 days and compared to the density of the population. It is expressed for 100,000 inhabitants and enables to compare geographic areas.
The incidence rate can change depending on testing activities and time needed to get results. Each department is listed in three colors:
