Semaine 202602 - Acute Respiratory Infection (ARI) - Moderate activity in general practice

Lundi 05 janv. 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 (2026w02), the incidence rate of acute respiratory infection (ARI) cases consulting in general practice was estimated at 322 cases per 100,000 population (95% CI [311; 334]).
Subject to future data consolidation, this rate has risen slightly for the second consecutive week and corresponds to a similar level of activity than those usually observed at this time of the year (consolidated data for 2026w01: 280 [269; 291]).

At the regional level, the highest incidence rates were noted in: Bretagne (618 [551; 684]), Corse (464 [337; 590]) and Nouvelle-Aquitaine (438 [390; 486]). 

Influenza: the incidence rate of influenza cases seen in general practice for an ARI was estimated at 143 cases per 100,000 population (95% CI [118; 168]) (data sources: Sentinelles, SOS Médecins, DMGs Côte d'Azur, Rouen and Strasbourg).
Subject to future data consolidation, this rate is decreasing for the third week in a row but remains at a moderate level of activity (consolidated data for 2026w01: 181 [151; 210]).

RSV infection: the incidence rate of RSV infection cases seen in general practice for an ARI was estimated at 34 cases per 100,000 population (95% CI [22; 45]), corresponding to 22,564 [15,048; 30,080] new cases (data sources: Sentinelles, SOS Médecins, DMGs Côte d'Azur, Rouen and Strasbourg).
Subject to future data consolidation, this rate is stable compared to the previous weeks and corresponds to a high level of activity.  (consolidated data for 2026w01: 29 [17; 41]).

Bronchiolitis in children under one year old : the incidence of bronchiolitis cases in children under 1 seen in general practice was estimated at 442 cases per 100,000 population (95% CI [217; 667]) (data source: IQVIA (EMR)).
Subject to future data consolidation, this rate is stable compared to the previous weeks and corresponds to a lower level of activity than those usually observed at this time of the year.  (consolidated data for 2026w01: 296 [145; 447]).

Covid-19: the incidence rate of Covid-19 cases seen in general practice for an ARI was estimated at 7 cases per 100,000 population (95% CI [4; 9]) (data source: Sentinelles).
Subject to future data consolidation, this rate is stable compared to the previous week and  corresponds to a low level of activity (consolidated data for 2026w01: 8 [6; 11]).

Semaine 202602 - Acute diarrhea - Low activity in general practice

Lundi 05 janv. 2026

The purpose of acute diarrhea surveillance is to monitor gastroenteritis outbreaks.

In mainland France, last week (2026w02), the incidence rate of acute diarrhea cases seen in general practice was estimated at 74 cases per 100,000 population (95% CI [69; 80]). 
Subject to future data consolidation, this rate is increasing compared to the previous week but corresponds to a lower level of activity those usually observed at this time of the year (consolidated data for 2026w01: 61 [56; 67]).

At the regional level, the highest incidence rates were noted in: Provence-Alpes-Côte d'Azur (141 [104; 177]), Nouvelle-Aquitaine (105 [82; 128]) and Occitanie (104 [82; 126]).

Semaine 202602 - Chickenpox - Low activity in general practice

Lundi 05 janv. 2026

 
In mainland France, last week (2026w02), the incidence rate of Chickenpox cases seen in general practice was estimated at 9 cases per 100,000 population (95% CI [7; 11]). 
Subject to future data consolidation, this rate is stable compared to the previous weeks and corresponds to a lower level of activity than those usually observed at this time of the year (consolidated data for 2026w01: 11 [9; 13]).

At the regional level, the highest incidence rates were noted in: Corse (35 [2; 69]), Pays de la Loire (23 [7; 38]) and Centre-Val de Loire (22 [5; 38]).
