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 (2025w13), the incidence rate of acute respiratory infection (ARI) cases consulting in general practice was estimated at 122 cases per 100,000 population (95% CI [107; 137]) (data source: Sentinelles).
Subject to future data consolidation, this rate is slightly decreasing compared to the previous week (consolidated data for 2025w12: 142 [128; 156]).

At the regional level, the highest incidence rates were noted in: Grand Est (277 [198; 356]), Bretagne (190 [12; 258]) and Provence-Alpes-Côte d’Azur (175 [79; 272]).

Influenza: the incidence rate of influenza cases seen in general practice for an ARI was estimated at 5 cases per 100,000 population (95% CI [0; 9]). Subject to future data consolidation, this rate is decreasing compared to the previous week (consolidated data for 2025w12:  38 [28; 47]) (data sources: Sentinelles, SOS Médecins, DUMG Rouen and DERMG Côte d’Azur).

RSV infection: the incidence rate of RSV infection cases seen in general practice for an ARI was estimated at 8 cases per 100,000 population (95% CI [3; 13]). Subject to future data consolidation, this rate is stable compared to the previous week (consolidated data for 2025w12: 2 [0; 4]) (data sources: Sentinelles, SOS Médecins, Rouen and Côte d’Azur Universities).

Covid-19: the incidence rate of Covid-19 cases seen in general practice for acute respiratory infection was estimated at 5 cases per 100,000 population (95% CI [3; 8]). Subject to future data consolidation, this rate is stable compared to the previous week (consolidated data for 2025w12: 6 [4; 8]) (data source: Sentinelles).

Acute diarrhea   Définition

  Moderate activity in general practice

Previously on sentiweb            

 The purpose of acute diarrhea surveillance is to monitor gastroenteritis outbreaks.

In mainland France, last week (2025w13), the incidence rate of acute diarrhea cases seen in general practice was estimated at 108 cases per 100,000 population (95% CI [94; 123])
Subject to future data consolidation, this rate is stable compared to the previous week and corresponds to a similar activity level compared to those usually observed at this time of the year (consolidated data for 2025w12: 105 [94; 116]).

At the regional level, the highest incidence rates were noted in: Bretagne (163 [99; 228]), Normandie (157 [36; 279]) and Provence-Alpes-Côte d’Azur (148 [55; 242]).

In mainland France, last week (2025w13), the incidence rate of Chickenpox cases seen in general practice was estimated at 10 cases per 100,000 population (95% CI [6; 14])
Subject to future data consolidation, this rate is stable compared to the previous weeks and corresponds to a lower activity level than those usually observed at this time of the year (consolidated data for 2025w12: 6 [3; 9]).

At the regional level, the highest incidence rates were noted in: Hauts-de-France (53 [17; 88]), Provence-Alpes-Côte d’Azur (11 [0; 36]) and Grand Est (10 [0; 25]).

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.
