Semaine 202619 - Acute Respiratory Infection (ARI) - Low activity in general practice

Lundi 04 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 (2026w19), the incidence rate of acute respiratory infection (ARI) cases consulting in general practice was estimated at 52 cases per 100,000 population (95% CI [47; 56]).
Subject to future data consolidation, this rate is stable compared to the previous week and corresponds to a lower activity level than those usually observed at this time of the year (consolidated data for 2026w18: 53 [48; 58]).

At the regional level, the highest incidence rates were noted in: Bretagne (125 [91; 159]), Nouvelle-Aquitaine (56 [39; 73]) and Auvergne-Rhône-Alpes (54 [37; 71]). 

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 week (consolidated data for 2026w18: 1 [0; 1]) and corresponds to a low level of activity.

Lundi 04 mai 2026

The purpose of acute diarrhea surveillance is to monitor gastroenteritis outbreaks.
 
In mainland France, last week (2026w19), the incidence rate of acute diarrhea cases seen in general practice was estimated at 51 cases per 100,000 population (95% CI [46; 56]). 
Subject to future data consolidation, this rate is slightly 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 2026w18: 44 [39; 48]).

At the regional level, the highest incidence rates were noted in: Provence-Alpes-Côte d'Azur (77 [54; 99]), Hauts-de-France (73 [52; 94]) and Bretagne (67 [42; 91]).

Subject to future data consolidation, this rate is decreasing compared to the previous week and corresponds to a lower activity level than those usually observed at this time of the year (consolidated data for 2026w18: 13 [10; 15]).

At the regional level, the highest incidence rates were noted in: Pays de la Loire (16 [1; 30]), Nouvelle-Aquitaine (13 [5; 21]) and Ile-de-France (12 [7; 17]).
