Semaine 202542 - Acute Respiratory Infection (ARI) - Moderate activity in general practice

Lundi 13 oct. 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 (2025w42), the incidence rate of acute respiratory infection (ARI) cases consulting in general practice was estimated at 195 cases per 100,000 population (95% CI [187; 204]) (data sources: Sentinelles and IQVIA)).
Subject to future data consolidation, this rate is stable 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 2025w41: 197 [189; 205]).

At the regional level, the highest incidence rates were noted in: Grand Est (300 95% CI [264 ; 336]), Bretagne (298 [251 ; 345]) and Nouvelle-Aquitaine (262 [228 ; 296]). 

Covid-19: the incidence rate of Covid-19 cases seen in general practice for an ARI was estimated at 28 cases per 100,000 population (95% CI [23; 34]) (data source: Sentinelles). 
Subject to future data consolidation, this rate has been decreasing since three weeks but remains at a moderate activity level (consolidated data for 2025w41: 41 [34; 45]).

Influenza: the incidence rate of influenza cases seen in general practice for an ARI was estimated at 3 cases per 100,000 population (95% CI [1; 5]) (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 2025w41: 3 [0; 7]). No active circulation of influenza viruses is observed in general practice.

RSV infection: the incidence rate of RSV infection cases seen in general practice for an ARI was estimated at 3 cases per 100,000 population (95% CI [1; 5]), corresponding to 1,980 [383; 3,577] new cases (data sources: Sentinelles, SOS Médecins, Rouen and Côte d'Azur Universities).
Subject to future data consolidation, this rate is stable compared to the previous week (consolidated data for 2025w41: 2 [0; 4]). No active circulation of RSV is observed in general practice.

Bronchiolitis in children under 1 : the incidence rate of bronchiolitis cases in children under 1 seen in general practice was estimated at 199 cases per 100,000 population (95% CI [90; 308]) (data source: IQVIA).
Subject to future data consolidation, this rate is stable compared to the previous weeks (data consolidated for 2025w41: 279 [154 ; 404]).

Semaine 202542 - Acute diarrhea - Low activity in general practice

Lundi 13 oct. 2025

The purpose of acute diarrhea surveillance is to monitor gastroenteritis outbreaks.
 
In mainland France, last week (2025w42), the incidence rate of acute diarrhea cases seen in general practice was estimated at 56 cases per 100,000 population (95% CI [51; 60]). 
Subject to future data consolidation, this rate is stable compared to the previous weeks and corresponds to a lower activity level than those usually observed at this time of the year (consolidated data for 2025w41: 59 [54; 63]).

At the regional level, the highest incidence rates were noted in: Corse (102 [28; 175]), Grand Est (77 [58; 96]) and Provence-Alpes-Côte d'Azur (74 [54; 95]).

Semaine 202542 - Chickenpox - Low activity in general practice

Lundi 13 oct. 2025

In mainland France, last week (2025w42), the incidence rate of Chickenpox cases seen in general practice was estimated at 6 cases per 100,000 population (95% CI [4; 7]). 
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 2025w41: 6 [5 ; 7]).

At the regional level, the highest incidence rates were noted in: Nouvelle-Aquitaine (12 [4; 20]), Normandie (10 [1; 20]), Bretagne (10 [2; 19]) and Bourgogne-Franche-Comté (9 [0; 19])
