Lundi 26 mai 2025
ARI are caused by a variety of respiratory viruses including SARS-CoV-2 (Covid-19), influenza viruses, and other respiratory viruses such as RSV, rhinovirus, and metapneumovirus. The purpose of ARI surveillance is to monitor outbreaks of these viruses.In mainland France, last week (2025w22), the incidence rate of acute respiratory infection (ARI) cases consulting in general practice was estimated at 79 cases per 100,000 population (95% CI [65; 93]).
Subject to future data consolidation, this rate is stable compared to the previous week and corresponds to a similar level of activity to that usually observed at this time of the year (consolidated data for 2025w21: 89 [77; 102]).
At the regional level, the highest incidence rates were noted in: Grand Est (155 [67; 244]), Bretagne (107 [46; 168]) and Nouvelle-Aquitaine (103 [61; 146]).
Covid-19: the incidence rate of Covid-19 cases seen in general practice for an ARI was estimated at 8 cases per 100,000 population (95% CI [5; 11]).
