Semaine 202643 - Acute Respiratory Infection (ARI) - Low activity in general practice

Lundi 19 oct. 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 (2026w43), the incidence rate of acute respiratory infection (ARI) cases consulting in general practice was estimated at 166 cases per 100,000 population (95% CI [158; 174]) (data sources: Sentinelles and IQVIA (EMR)).
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 2026w42: 162 [155; 170]).

At the regional level, the highest incidence rates were noted in: Bretagne (266 [217; 314]), Bourgogne-Franche-Comté (247 [202; 292]) and Provence-Alpes-Côte d'Azur (227 [192; 262]).

Covid-19: the incidence rate of Covid-19 cases seen in general practice for an ARI was estimated at 18 cases per 100,000 population (95% CI [12; 23]) (data source: Sentinelles).
Subject to future data consolidation, this rate is slightly increasing compared to the previous week (consolidated data for 2026w42: 14 [11; 17])  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, DMGs Côte d'Azur, Rouen and Strasbourg).
Subject to future data consolidation, this rate is stable compared to the previous week (consolidated data for 2026w42: 8 [4; 11])  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 1 cases per 100,000 population (95% CI [0; 3]) (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 week (consolidated data for 2026w42: 1 [0; 2])  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 124 cases per 100,000 population (95% CI [34; 214]) (data source: IQVIA (EMR)).
Subject to future data consolidation, this rate is stable compared to the previous week (consolidated data for 2026w42: 142 [57; 227]) and corresponds to a low activity level.

Semaine 202643 - Acute diarrhea - Low activity in general practice

Lundi 19 oct. 2026

The purpose of acute diarrhea surveillance is to monitor gastroenteritis outbreaks.
 
In mainland France, last week (2026w43), the incidence rate of acute diarrhea cases seen in general practice was estimated at 47 cases per 100,000 population (95% CI [43; 52]). 
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 2026w42: 51 [46; 55]).

At the regional level, the highest incidence rates were noted in: Grand Est (69 [51; 88]), Provence-Alpes-Côte d'Azur (64 [45; 83]) and Pays de la Loire (61 [31; 91]).

Semaine 202643 - Chickenpox - Low activity in general practice

Lundi 19 oct. 2026

In mainland France, last week (2026w43), the incidence rate of chickenpox cases seen in general practice was estimated at 5 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 2026w42: 3 [2; 5]).

At the regional level, the highest incidence rates were noted in: Centre-Val de Loire (11 [1; 21]), Pays de la Loire (10 [0; 24]) and Grand Est (7 [1; 13]).
