Semaine 202621 - Acute Respiratory Infection (ARI) - Low activity in general practice

Lundi 18 mai 2026

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 (2026w21), the incidence rate of acute respiratory infection (ARI) cases consulting in general practice was estimated at 65 cases per 100,000 population (95% CI [59; 70]) (data sources: Sentinelles and IQVIA (EMR)).
Subject to future data consolidation, this rate is increasing compared to the previous week and corresponds to a similar activity level to those usually observed at this time of the year (consolidated data for 2026w20: 50 [45; 55]).

At the regional level, the highest incidence rates were noted in: Bretagne (180 [141; 219]), Bourgogne-Franche-Comté (108 [73; 142]) and Provence-Alpes-Côte d'Azur (83 [58; 108]). 

Covid-19: the incidence rate of Covid-19 cases seen in general practice for an ARI was estimated at 0 case per 100,000 population (data source: Sentinelles).
Subject to future data consolidation, this rate is stable compared to the previous weeks (consolidated data for 2026w20: 0) and corresponds to a very low level of activity.

Subject to future data consolidation, this rate is increasing compared to the previous week and corresponds to a similar activity level to those usually observed at this time of the year (consolidated data for 2026w20: 41 [37; 45]).

At the regional level, the highest incidence rates were noted in: Hauts-de-France (80 [58; 101]), Provence-Alpes-Côte d'Azur (77 [53; 100]) and Pays de la Loire (55 [25; 85]).

At the regional level, the highest incidence rates were noted in: Normandie (31 [8; 55]), Bretagne (19 [5; 32]), Provence-Alpes-Côte d'Azur (19 [7; 31]), Centre-Val de Loire (19 [3; 35]) and Corse (18 [0; 46]).
