Acute Respiratory Infection (ARI) Covid-19, Influenza and other respiratory viruses Définition
Low activity in general practice
Previously on sentiweb
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 (2025w16), the incidence rate of acute respiratory infection (ARI) cases consulting in general practice was estimated at 124 cases per 100,000 population (95% CI [104; 144]).
Subject to future data consolidation, this rate is stable compared to the previous weeks and corresponds to a similar activity level than those usually observed at this time of the year (consolidated data for 2025w15: 119 [106; 133]).
At the regional level, the highest incidence rates were noted in: Nouvelle-Aquitaine (206 [106; 306]), Provence-Alpes-Côte d’Azur (202 [78; 326]) and Bretagne (192 [126; 258]).
Covid-19: the incidence rate of Covid-19 cases seen in general practice for acute respiratory infection was estimated at 8 cases per 100,000 population (95% CI [5; 11]).
Subject to future data consolidation, this rate remains stable compared to the previous weeks and is at a low level of activity (consolidated data for 2025w15: 5 [3; 11]).

Acute diarrhea Définition
Low activity in general practice
Previously on sentiweb
The purpose of acute diarrhea surveillance is to monitor gastroenteritis outbreaks.
In mainland France, last week (2025w16), the incidence rate of acute diarrhea cases seen in general practice was estimated at 78 cases per 100,000 population (95% CI [63 ; 93]).
Subject to future data consolidation, this rate is stable compared to the previous week and corresponds to a similar activity level than those usually observed at this time of the year (consolidated data for 2025w15: 71 95% CI [60 ; 81]).
At the regional level, the highest incidence rates were noted in: Pays de la Loire (142 [0; 381]), Nouvelle-Aquitaine (107 [54; 161]) and Occitanie (104 [53; 156]).

In mainland France, last week (2025w16), the incidence rate of Chickenpox cases seen in general practice was estimated at 11 cases per 100,000 population (95% CI [6 ; 16]).
Subject to future data consolidation, this rate is slightly increasing compared to the previous weeks but corresponds to a low activity level compared to those usually observed at this time of the year (consolidated data for 2025w15: 8 [5; 12]).
At the regional level, the highest incidence rates were noted in: Provence-Alpes-Côte d’Azur (21 [0; 60]), Centre-Val de Loire (19 [0; 45]) and Corse (18 [0; 50]).

Surveillance of acute respiratory infections by the Sentinelles network (Covid-19, influenza and RSV infections)
In March 2020, following the emergence of SARS-CoV-2 (COVID-19), the “Sentinelles surveillance” evolved. The surveillance of “influenza-like illness” (ILI, defined as sudden onset of fever above 39°C, accompanied by myalgia and respiratory signs) has been replaced by “acute respiratory infections” (ARI, defined as sudden onset of fever or feeling of fever and respiratory signs).
This new surveillance enables both the monitoring of the COVID-19 pandemic and epidemics due to other respiratory viruses (influenza, respiratory syncytial virus (RSV), rhinovirus and metapneumovirus). This surveillance is carried out with “Santé publique France” (the national agency for public health), the National Reference Center for respiratory infections (“Institut Pasteur” and “Hospices Civils de Lyon”) and the University of Corsica. This surveillance is based on patients consulting a general practitioner or a paediatrician for an ARI.
Data from the Sentinelles network are integrated into the overall national COVID-19 surveillance coordinated by “Santé publique France”. For more information, you can consult the weekly COVID-19 and influenza newsletters from “Santé publique France”.
At the same time, the Sentinelles network is carrying out studies and research on Covid-19, which are presented in the “Covid-19” section of this website.
