Semaine 202601 - Acute Respiratory Infection (ARI) - Moderate activity in general practice

Lundi 29 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 (2026w01), the incidence rate of acute respiratory infection (ARI) cases consulting in general practice was estimated at 292 cases per 100,000 population (95% CI [280; 304]).
Subject to future data consolidation, this rate is slightly increasing compared to the previous week and corresponds to a similar level of activity than those usually observed at this time of the year (consolidated data for 2025w52: 271 [260; 282]).

At the regional level, the highest incidence rates were noted in: Bretagne (704 [620; 787]), Nouvelle-Aquitaine (481 [429; 532]) and Provence-Alpes-Côte d'Azur (400 [342; 458]). 

Influenza: the incidence rate of influenza cases seen in general practice for an ARI was estimated at 190 cases per 100,000 population (95% CI [152; 227]) (data sources: Sentinelles, SOS Médecins, DMGs (Côte d'Azur, Rouen, Strasbourg)).
Subject to future data consolidation, this rate is stable (consolidated data for 2025w52: 190 [164; 216]) and corresponds to a moderate level of activity.

RSV infection: the incidence rate of RSV infection cases seen in general practice for an ARI was estimated at 45 cases per 100,000 population (95% CI [26; 65]) (data sources: Sentinelles, SOS Médecins, DMGs (Côte d'Azur, Rouen, Strasbourg)).
Subject to future data consolidation, this rate is slightly increasing (consolidated data for 2025w52: 28 [18; 39]) and corresponds to a high level of activity.

Bronchiolitis in children under one year old : the incidence rate of bronchiolitis cases in children under 1 seen in general practice was estimated at 297 cases per 100,000 population (95% CI [145; 449]) (data source: IQVIA (EMR)).
Subject to future data consolidation, this rate is decreasing (consolidated data for 2025w52: 379 [211; 547]) and corresponds to a lower level of activity than those usually observed at this time of the year.

Covid-19: the incidence rate of Covid-19 cases seen in general practice for an ARI was estimated at 11 cases per 100,000 population (95% CI [7; 15]) (data source: Sentinelles).
Subject to future data consolidation, this rate is stable (consolidated data for 2025w52: 7 [4; 9]) and corresponds to a low level of activity.

Semaine 202601 - Acute diarrhea - Low activity in general practice

Lundi 29 déc. 2025

The purpose of acute diarrhea surveillance is to monitor gastroenteritis outbreaks.
 
In mainland France, last week (2026w01), the incidence rate of acute diarrhea cases seen in general practice was estimated at 63 cases per 100,000 population (95% CI [57; 68]). 
Subject to future data consolidation, this rate is slightly increasing 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 2025w52: 44 [40; 48]).

At the regional level, the highest incidence rates were noted in: Nouvelle-Aquitaine (130 [101; 159]), Provence-Alpes-Côte d'Azur (106 [77; 136]) and Occitanie (101 [69; 133]).

Semaine 202601 - Chickenpox - Low activity in general practice

Lundi 29 déc. 2025

 
In mainland France, last week (2026w01), the incidence rate of Chickenpox cases seen in general practice was estimated at 11 cases per 100,000 population (95% CI [9; 14]). 
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 2025w52: 9 [7; 11]).

At the regional level, the highest incidence rates were noted in: Corse (32 [0; 80]), Auvergne-Rhône-Alpes (20 [9; 30]), Bretagne (18 [4; 31]) and Pays de la Loire (18 [5; 31]).
