Semaine 202517 - Acute Respiratory Infection (ARI) - Low activity in general practice
Lundi 21 avr. 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 (2025w17), the incidence rate of acute respiratory infection (ARI) cases consulting in general practice was estimated at 89 cases per 100,000 population (95% CI [75; 103]).
Subject to future data consolidation, this rate is slightly decreasing compared to the previous weeks and corresponds to a similar activity level than those usually observed at this time of the year (consolidated data for 2025w16: 98 [85; 112]).
At the regional level, the highest incidence rates were noted in: Bretagne (177 [93; 262]), Auvergne-Rhône-Alpes (139 [88; 190]) and Grand Est (126 [68; 184]).
Covid-19: the incidence rate of Covid-19 cases seen in general practice for an ARI was estimated at 10 cases per 100,000 population (95% CI [7; 13]).
Subject to future data consolidation, this rate has risen slightly for two consecutive weeks (consolidated data for 2025w16: 7 [5; 10]).
