Acute Respiratory Infection (ARI) Covid-19, Influenza and other respiratory viruses Définition
Moderate activity in general practice
Previously on sentiweb
In mainland France, last week (2025w39), the incidence rate of acute respiratory infection (ARI) cases consulting in general practice was estimated at 222 cases per 100,000 population (95% CI [202; 243]).
Subject to future data consolidation, this rate has risen for the third consecutive week and corresponds to a level of activity slightly higher than those usually observed at this time of the year (consolidated data for 2025w38: 175 [160; 190]).
At the regional level, the highest incidence rates were noted in: Bretagne (336 [253; 419]), Corse (311 [73; 549]) and Grand Est (296 [222; 370]).
Covid-19: the incidence rate of Covid-19 cases seen in general practice for an ARI was estimated at 50 cases per 100,000 population (95% CI [42; 57]), corresponding to 33,461 [28,469; 38,453] new cases.
Subject to future data consolidation, this rate is stable compared to the previous weeks and remains at a moderate level of activity (consolidated data for 2025w38: 47 [41; 54]).

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illness” (ILI, defined as sudden onset of fever above 39°C, accompanied by myalgia and respiratory signs) has been replaced by “acute respiratory infections” (ARI, defined as sudden onset of fever or feeling of fever and respiratory signs).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.
