Semaine 202605 - Acute Respiratory Infection (ARI) - Moderate activity in general practice

Lundi 26 janv. 2026

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 (2026w05), the incidence rate of acute respiratory infection (ARI) cases consulting in general practice was estimated at 367 cases per 100,000 population (95% CI [355; 379]).
Subject to future data consolidation, this rate is stable compared to the previous week and corresponds to a similar activity level to those usually observed at this time of the year (consolidated data for 2026w04: 363 [351; 374]).

At the regional level, the highest incidence rates were noted in: Bretagne (469 [414; 525]), Provence-Alpes-Côte d'Azur (458 [402; 514]), Bourgogne-Franche-Comté (458 [392; 524]) and Auvergne-Rhône-Alpes (405 [369; 441]). 

Influenza: the incidence rate of influenza cases seen in general practice for an ARI was estimated at 132 cases per 100,000 population (95% CI [112; 151]), corresponding to 88,708 [75,512; 101,904] new cases (data sources: Sentinelles, SOS Médecins, DMGs Côte d'Azur, Rouen and Strasbourg).
Subject to future data consolidation, this rate is decreasing compared to the previous week (consolidated data for 2026w04:  176 [155; 197]), 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 31 cases per 100,000 population (95% CI [22; 39]), corresponding to 20,697 [15,025; 26,369] new cases (data sources: Sentinelles, SOS Médecins, DMGs Côte d'Azur, Rouen and Strasbourg).
Subject to future data consolidation, this rate is slightly increasing compared to the previous week (consolidated data for 2026w04: 21 [14; 28]) and corresponds to a moderate level of activity.

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 381 cases per 100,000 population (95% CI [192; 570]) (data source: IQVIA (EMR)).
Subject to future data consolidation, this rate is stable compared to the previous weeks (consolidated data for 2026w04: 373 [204; 542]).

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 [4; 16]), corresponding to 6,810 [2,844; 10,776] new cases (data source: Sentinelles).
Subject to future data consolidation, this rate is stable compared to the previous week (consolidated data for 2026w04: 9 [5; 13]) and corresponds to a low level of activity.

Semaine 202605 - Acute diarrhea - Low activity in general practice

Lundi 26 janv. 2026

The purpose of acute diarrhea surveillance is to monitor gastroenteritis outbreaks.
 
In mainland France, last week (2026w05), the incidence rate of acute diarrhea cases seen in general practice was estimated at 101 cases per 100,000 population (95% CI [95 ; 107]). 
Subject to future data consolidation, this rate is slightly increasing compared to the previous week and corresponds to a low level of activity compared to those usually observed at this time of the year (consolidated data for 2026w04: 93 [87; 98]).

At the regional level, the highest incidence rates were noted in: Provence-Alpes-Côte d'Azur (227 [185; 270]), Corse (149 [75; 223]) and Bretagne (128 [98; 158]).

Semaine 202605 - Chickenpox - Low activity in general practice

Lundi 26 janv. 2026

In mainland France, last week (2026w05), the incidence rate of chickenpox cases seen in general practice was estimated at 12 cases per 100,000 population (95% CI [9; 14]). 
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 2026w04: 9 [7; 11]).

At the regional level, the highest incidence rates were noted in: Corse (29 [0; 62]), Hauts-de-France (24 [13; 34]) and Pays de la Loire (19 [3; 35]).

Data sources: Sentinelles and IQVIA (EMR)
