Semaine 202618 - Acute Respiratory Infection (ARI) - Low activity in general practice

Lundi 27 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 (2026w18), the incidence rate of acute respiratory infection (ARI) cases consulting in general practice was estimated at 50 cases per 100,000 population (95% CI [45; 55]).
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 2026w17: 69 [63; 74]) (data sources: Sentinelles and IQVIA (EMR)).

 At the regional level, the highest incidence rates were noted in: Bretagne (120 [88; 152]), Grand Est (64 [46; 82]), and Nouvelle-Aquitaine (61 [43; 79]).

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; 1]) (data source: Sentinelles).
Subject to future data consolidation, this rate is stable compared to the previous weeks (consolidated data for 2026w17: 1 [0; 2]) and corresponds to a low level of activity.

Lundi 27 avr. 2026

The purpose of acute diarrhea surveillance is to monitor gastroenteritis outbreaks.
 
In mainland France, last week (2026w18), the incidence rate of acute diarrhea cases seen in general practice was estimated at 42 cases per 100,000 population (95% CI [37; 46]). 
Subject to future data consolidation, this rate is slightly 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 2026w17: 49 [44; 54]).

At the regional level, the highest incidence rates were noted in: Pays de la Loire (72 [40; 105]), Provence-Alpes-Côte d'Azur (62 [42; 81]) and Corse (51 [2; 101]).

Semaine 202618 - Chickenpox - Low activity in general practice

Lundi 27 avr. 2026

In mainland France, last week (2026w18), the incidence rate of chickenpox cases seen in general practice was estimated at 12 cases per 100,000 population (95% CI [10; 15]). 
Subject to future data consolidation, this rate is slightly decreasing 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 2026w17: 14 [12; 17]).

At the regional level, the highest incidence rates were noted in: Hauts-de-France (24 [12; 36]), Pays de la Loire (22 [3; 41]) and Normandie (21 [6; 37]).

Data sources: Sentinelles and IQVIA (EMR)
