In Week 18, there was a sharp decline in the regional incidence rate (IR) and positivity rate (PR) calculated from PCR and antigen tests (source: Sidep, Santé publique France). The IR fell from 614.7 per 100,000 inhabitants in Week 17 to 490.3 per 100,000 inhabitants in Week 18. IRs are down in all four departments: Côtes d’Armor (IR at 445, -169 points), Finistère (IR at 520, -110 points), Ille-et-Vilaine (IR at 465, -120 points), and Morbihan (IR at 525, -113 points). This decline in the incidence rate is observed across all age groups except among those under 15, for whom the incidence rate is stable or even rising slightly.
