Semaine 202615 - Acute Respiratory Infection (ARI) - Low activity in general practice

Lundi 06 avr. 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 (2026w15), the incidence rate of acute respiratory infection (ARI) cases consulting in general practice was estimated at 77 cases per 100,000 population (95% CI [72; 83]).
Subject to future data consolidation, this rate is decreasing 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 2026w14: 100 [93; 106]).

At the regional level, the highest incidence rates were noted in: Bretagne (206 [162; 249]), Grand Est (116 [89; 143]) and Nouvelle-Aquitaine (91 [63; 118]). 

Influenza: the incidence rate of influenza cases seen in general practice for an ARI was estimated at 12 cases per 100,000 population (95% CI [3; 21]) (data sources: Sentinelles, SOS Médecins, DMGs Côte d'Azur, Rouen and Strasbourg)
Subject to future data consolidation, this rate is stable compared to the previous weeks (consolidated data for 2026w14:  4 [1; 7]) and corresponds to a low level of activity.

RSV infection: the incidence rate of RSV infection cases seen in general practice for an ARI was estimated at 0 case per 100,000 population (95% CI [0; 15]) (data sources: Sentinelles, SOS Médecins, DMGs Côte d'Azur, Rouen and Strasbourg).
Subject to future data consolidation, this rate is stable compared to the previous weeks (consolidated data for 2026w14: 2 [0; 4]) and corresponds to a low 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 273 cases per 100,000 population (95% CI [93; 453]) (data source: IQVIA (EMR)).
Subject to future data consolidation, this rate is stable compared to the previous week (consolidated data for 2026w14: 292 [119; 465]) and corresponds to a low level of activity.

Covid-19: the incidence rate of Covid-19 cases seen in general practice for an ARI was estimated at 1 case per 100,000 population (95% CI [0; 3]) (data source: Sentinelles).
Subject to future data consolidation, this rate is stable compared to the previous weeks (consolidated data for 2026w14: 2 [1; 3]) and corresponds to a low level of activity.

Semaine 202615 - Acute diarrhea - Low activity in general practice

Lundi 06 avr. 2026

The purpose of acute diarrhea surveillance is to monitor gastroenteritis outbreaks.
 
In mainland France, last week (2026w15), the incidence rate of acute diarrhea cases seen in general practice was estimated at 56 cases per 100,000 population (95% CI [51; 61]). 
Subject to future data consolidation, this rate is decreasing 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 2026w14: 72 [67; 78]).

At the regional level, the highest incidence rates were noted in: Hauts-de-France (73 [54; 93]), Nouvelle-Aquitaine (69 [49; 88]) and Grand Est (68 [49; 88]).

Data sources: Sentinelles and IQVIA (EMR)

Semaine 202615 - Chickenpox - Low activity in general practice

Lundi 06 avr. 2026

In mainland France, last week (2026w15), the incidence rate of chickenpox cases seen in general practice was estimated at 15 cases per 100,000 population (95% CI [12 ; 17]). 
Subject to future data consolidation, this rate is slightly increasing 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 2026w14: 12 [10; 15]).

At the regional level, the highest incidence rates were noted in: Grand Est (24 [9; 39]), Bretagne (22 [8; 36]) and Hauts-de-France (21 [11; 31]).
