COVID-19 and Influenza Surveillance : role of the Sentinelles network

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illness” (ILI, defined as sudden onset of fever above 39°C, accompanied by myalgia and respiratory signs) has been replaced by “acute respiratory infections” (ARI, defined as sudden onset of fever or feeling of fever and respiratory signs).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, rhinovirus and metapneumovirus), based on patients consulting a general practitioner for an ARI. 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.

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 leading studies and research works on the COVID-19 presented in the “COVID-19” section of this website.

Acute Respiratory Infection (ARI) (COVID-19, Influenza and other respiratory viruses)   Définition

  Moderate activity in general practice

Previously on sentiweb            

The purpose of ARI surveillance is to monitor outbreaks of influenza, COVID-19 and other seasonal respiratory viruses (RSV, rhinovirus and metapneumovirus).

In metropolitan France, last week (2022w02), the incidence rate of ARI consultating (or teleconsulting) in general practice was estimated at 213 cases per 100,000 inhabitants (95% CI [195 ; 231]). This rate is stable compared to week 2022w01 (consolidated data: 208 [191 ; 225]).

At the regional level, the highest incidence rates were noted in: Provence-Alpes-Côte d’Azur (610 [476 ; 744]), Corse (422 [216 ; 628]) and Hauts-de-France (252 [153 ; 351]).


COVID-19: the incidence rate of ARI due to SARS-CoV-2 (COVID-19) seen in general practice was still increasing and estimated at 96 cases per 100,000 population (95% CI [79; 114]), corresponding to 63,820 [52,232; 75,408] new cases of COVID-19 seen in general practice.

INFLUENZA: stabilization of the circulation of influenza viruses.

Other respiratory viruses: low circulation of RSV, metapneumovirus and rhinovirus observed in week 2022w02.

Acute diarrhea   Définition

  Moderate activity in general practice

Previously on sentiweb            

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

In metropolitan France, last week (2022w02), the incidence rate of acute diarrhea seen in general practice was estimated at 106 cases per 100,000 inhabitants (95% CI [91 ; 121]). This rate is stable compared to week 2022w01 (consolidated data: 114 95% CI [101 ; 127]) with a lower activity level than those usually observed in this period

At the regional level, the highest incidence rates were noted in: Grand Est (176 [91 ; 261]), Bretagne (148 [87 ; 209]) and Nouvelle-Aquitaine (137 [81 ; 193]).
