Semaine 202545 - Acute Respiratory Infection (ARI) - Low to moderate activity in general practice

Lundi 03 nov. 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 (2025w45), the incidence rate of acute respiratory infection (ARI) cases consulting in general practice was estimated at 138 cases per 100,000 population (95% CI [130; 145]) (data sources: Sentinelles and IQVIA (EMR)).
Subject to future data consolidation, this rate has decreased slightly over the past several weeks but corresponds to a similar level of activity compared to those usually observed at this time of the year (consolidated data for 2025w44: 158 [150; 166]).

At the regional level, the highest incidence rates were noted in: Grand Est (211 [180; 241]), Bretagne (156 [123; 190]) and Nouvelle-Aquitaine (185 [155; 216]).

Covid-19: the incidence rate of Covid-19 cases seen in general practice for an ARI was estimated at 10 cases per 100,000 population (95% CI [7; 13]) (data source: Sentinelles).
Subject to future data consolidation, this rate continues the decrease observed in recent weeks (consolidated data for 2025w44: 11 [8; 14]).

RSV infection: the incidence rate of RSV infection cases seen in general practice for an ARI was estimated at 6 cases per 100,000 population (95% CI [3; 10]) (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 2025w44: 9 [6; 13]).

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 267 cases per 100,000 population (95% CI [143; 391]) (data source: IQVIA (EMR)).
Subject to future data consolidation, this rate is stable compared to the previous week (data consolidated for 2025w44: 299 [156; 442]).

Influenza: the incidence rate of influenza cases seen in general practice for an ARI was estimated at 8 cases per 100,000 population (95% CI [4; 11]) (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 week (consolidated data for 2025w44: 5 [2; 9]).

Semaine 202545 - Acute diarrhea - Low activity in general practice

Lundi 03 nov. 2025

The purpose of acute diarrhea surveillance is to monitor gastroenteritis outbreaks.
 
In mainland France, last week (2025w45), the incidence rate of acute diarrhea cases seen in general practice was estimated at 54 cases per 100,000 population (95% CI [49; 58]). 
Subject to future data consolidation, this rate is slightly increasing compared to the previous week but corresponds to a lower activity level than those usually observed at this time of the year (consolidated data for 2025w44: 46 [42; 50]).

At the regional level, the highest incidence rates were noted in: Grand Est (72 [54; 90]), Corse (70 [20; 121]), Provence-Alpes-Côte d'Azur (61 [41; 80]) and Normandie (61 [38; 84]).

Semaine 202545 - Chickenpox - Low activity in general practice

Lundi 03 nov. 2025

In mainland France, last week (2025w45), 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 2025w44: 7 [6; 9]).

At the regional level, the highest incidence rates were noted in: Bretagne (13 [3; 23]), Centre-Val de Loire (11 [0; 22]), Hauts-de-France (10 [3; 16]) and Pays de la Loire (10 [1; 18]).
