Semaine 202639 - Acute Respiratory Infection (ARI) - Low activity in general practice

Lundi 21 sept. 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 (2026w39), the incidence rate of acute respiratory infection (ARI) cases consulting in general practice was estimated at 151 cases per 100,000 population (95% CI [144; 158]) (data sources: Sentinelles and IQVIA (EMR)).
Subject to future data consolidation, this rate is 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 2026w38: 103 [98; 109]).

At the regional level, the highest incidence rates were noted in: Bourgogne-Franche-Comté (310 [259; 361]), Bretagne (254 [212; 296]) and Hauts-de-France (186 [159; 214]). 

Covid-19: the incidence rate of Covid-19 cases seen in general practice for an ARI was estimated at 13 cases per 100,000 population (95% CI [9; 17]) (data source: Sentinelles).
Subject to future data consolidation, this rate is slightly increasing compared to the previous weeks (consolidated data for 2026w38: 9 [7; 11]) and corresponds to a low activity level.

Influenza: the incidence rate of influenza cases seen in general practice for an ARI was estimated at 4 cases per 100,000 population (95% CI [1; 7]) (data sources: Sentinelles, SOS Médecins and university departments of general practice).
Subject to future data consolidation, this rate is stable compared to the previous week (consolidated data for 2026w38: 5 [2; 9]) and corresponds to a low activity level.

RSV infection: the incidence rate of RSV infection cases seen in general practice for an ARI was estimated at 0 cases per 100,000 population (95% CI [0; 6]) (data sources: Sentinelles, SOS Médecins and university departments of general practice).
Subject to future data consolidation, this rate is stable compared to the previous week (consolidated data for 2026w38: 0 [0; 4]) and corresponds to a low activity level.

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 135 cases per 100,000 population (95% CI [45; 225]) (data source: IQVIA (EMR)).
Subject to future data consolidation, this rate is stable compared to the previous week (consolidated data for 2026w38: 236 [127; 345]) and corresponds to a low activity level.

Semaine 202639 - Acute diarrhea - Low activity in general practice

Lundi 21 sept. 2026

The purpose of acute diarrhea surveillance is to monitor gastroenteritis outbreaks.
 
In mainland France, last week (2026w39), the incidence rate of acute diarrhea cases seen in general practice was estimated at 50 cases per 100,000 population (95% CI [46; 55]). 
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 2026w38: 45 [41; 49]).

At the regional level, the highest incidence rates were noted in: Corse (95 [36; 154]), Grand Est (66 [49; 83]), Hauts-de-France (63 [48; 79]) and Provence-Alpes-Côte d'Azur (63 [45; 81]).

Semaine 202639 - Chickenpox - Low activity in general practice

Lundi 21 sept. 2026

In mainland France, last week (2026w39), the incidence rate of chickenpox cases seen in general practice was estimated at 4 cases per 100,000 population (95% CI [3; 5]). 
Subject to future data consolidation, this rate is slightly increasing 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 2026w38: 2 [1; 3]).

At the regional level, the highest incidence rates were noted in: Normandie (12 [0; 25]) and Auvergne-Rhône-Alpes (6 [2; 10]).
