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 (2025w44), the incidence rate of acute respiratory infection (ARI) cases consulting in general practice was estimated at 165 cases per 100,000 population (95% CI [156; 173]) (Data sources: Sentinelles and Electronic Medical Records (EMR) IQVIA).
Subject to future data consolidation, this rate is stable compared to the previous week and corresponds to a similar level of activity compared to those usually observed at this time of the year (consolidated data for 2025w43: 166 [158; 174]).

At the regional level, the highest incidence rates were noted in: Bourgogne-Franche-Comté (300 [252; 348]), Grand Est (245 [209; 281]) and Bretagne (240 [194; 286]). 

Covid-19: the incidence rate of Covid-19 cases seen in general practice for an ARI was estimated at 15 cases per 100,000 population (95% CI [10; 19]) corresponding to 9,878 [6,967; 12,789] new cases (Data source: Sentinelles).
Subject to future data consolidation, this rate continues the decrease observed for several weeks and is at a low level of activity (consolidated data for 2025w43: 20 [14; 25]).

RSV infection: the incidence rate of RSV infection cases seen in general practice for an ARI was estimated at 15 cases per 100,000 population (95% CI [9; 21]), corresponding to 10,095 [5,866; 14,324] new cases (data sources: Sentinelles, SOS Médecins, Rouen and Côte d’Azur Universities).
Subject to future data consolidation, this rate is increasing compared to the previous week, mainly in children (0-14 years old), but remains at a low level of activity (consolidated data for 2025w43: 7 [3; 11]).

Bronchiolitis in children under 1 : the incidence rate of bronchiolitis cases in children under 1 seen in general practice was estimated at 269 cases per 100,000 population (95% CI [132; 406]) (Data source: IQVIA (EMR)).
Subject to future data consolidation, this rate is slightly increasing compared to the previous week and is at a low level of activity (data consolidated for 2025w43: 171 [65; 277]).

Influenza: the incidence rate of influenza cases seen in general practice for an ARI was estimated at 5 cases per 100,000 population (95% CI [1; 9]), corresponding to 3,179 [361; 5,997] new cases (Data sources: Sentinelles, SOS Médecins, DUMG Rouen and DERMG Côte d’Azur).​​​​​
Subject to future data consolidation, this rate is stable compared to the previous weeks (consolidated data 2025w43: 2 [0; 4]). No active circulation of influenza viruses is observed for the moment in general practice.

The purpose of acute diarrhea surveillance is to monitor gastroenteritis outbreaks.
 
In mainland France, last week (2025w44), the incidence rate of acute diarrhea cases seen in general practice was estimated at 47 cases per 100,000 population (95% CI [42; 51]). 
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 2025w43: 46 [42; 51]).

At the regional level, the highest incidence rates were noted in: Bretagne (66 [42; 90]), Grand Est (58 [41; 74]) and Auvergne-Rhône-Alpes (53 [39; 68]).

In mainland France, last week (2025w44), the incidence rate of Chickenpox cases seen in general practice was estimated at 7 cases per 100,000 population (95% CI [6; 9]). 
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 2025w43: 5 [4; 7]).

At the regional level, the highest incidence rates were noted in: Pays de la Loire (24 [5; 42]), Bourgogne-Franche-Comté (16 [7; 25]) and Hauts-de-France (12 [5; 19]).
