Semaine 202552 - Acute Respiratory Infection (ARI) - Moderate activity in general practice

Lundi 22 déc. 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 (2025w52), the incidence rate of acute respiratory infection (ARI) cases consulting in general practice was estimated at 269 cases per 100,000 population (95% CI [258; 281]).
Subject to future data consolidation, this rate is decreasing compared to the previous week and corresponds to a similar level of activity to those usually observed at this time of the year (consolidated data for 2025w51: 343 [332; 355]). This observed stability will need to be confirmed in the coming weeks as the school holidays come to an end.

At the regional level, the highest incidence rates were noted in: Bretagne (541 [475; 607]), Nouvelle-Aquitaine (443 [396; 490]) and Provence-Alpes-Côte d'Azur (332 [278; 385]). 

Influenza: the incidence rate of influenza cases seen in general practice for an ARI was estimated at 200 cases per 100,000 population (95% CI [174; 225]) (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 week and is at a moderate level of activity (consolidated data for 2025w51: 215 [193; 237]).

RSV infection: the incidence rate of RSV infection cases seen in general practice for an ARI was estimated at 31 cases per 100,000 population (95% CI [20; 42]) (data sources: Sentinelles, SOS Médecins, DMGs Côte d'Azur, Rouen and Strasbourg).
Subject to future data consolidation, this rate is slightly decreasing compared to the previous week but remains at a high level of activity (consolidated data for 2025w51: 40 [30; 51]).

Bronchiolitis in children under one year old : the incidence rate of bronchiolitis cases in children under one year old seen in general practice was estimated at 327 cases per 100,000 population (95% CI [170; 484]) (data source: IQVIA (EMR)).
Subject to future data consolidation, this rate is slightly decreasing compared to the previous weeks (consolidated data for 2025w51: 428 [268; 588]).

Covid-19: the incidence rate of Covid-19 cases seen in general practice for an ARI was estimated at 6 cases per 100,000 population (95% CI [4; 8]) (data source: Sentinelles).
Subject to future data consolidation, this rate is stable compared to the previous week and is at a low level of activity (consolidated data for 2025w51: 10 [7; 12]).

Semaine 202552 - Acute diarrhea - Low activity in general practice

Lundi 22 déc. 2025

The purpose of acute diarrhea surveillance is to monitor gastroenteritis outbreaks.
 
In mainland France, last week (2025w52), the incidence rate of acute diarrhea cases seen in general practice was estimated at 44 cases per 100,000 population (95% CI [39; 48]). 
Subject to future data consolidation, this rate is decreasing compared to the previous week and corresponds to a lower level of activity than those usually observed at this time of the year (consolidated data for 2025w51: 70 [65; 75]).

At the regional level, the highest incidence rates were noted in: Grand Est (70 [50; 89]), Occitanie (64 [38; 89]) and Bretagne (61 [38; 84]).

Data sources: Sentinelles and IQVIA (EMR)

Semaine 202552 - Chickenpox - Low activity in general practice

Lundi 22 déc. 2025

In mainland France, last week (2025w52), the incidence rate of Chickenpox cases seen in general practice was estimated at 8 cases per 100,000 population (95% CI [6; 10]). 
Subject to future data consolidation, this rate is decreasing compared to the previous week and corresponds to a lower level of activity than those usually observed at this time of the year (consolidated data for 2025w51: 12 [10; 14]).

At the regional level, the highest incidence rates were noted in: Pays de la Loire (14 [3; 25]), Ile-de-France (12 [6; 18]) and Bretagne (11 [2; 21]).

Data sources: Sentinelles and IQVIA (EMR)
