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illness” (ILI, defined as sudden onset of fever above 39°C, accompanied by myalgia and respiratory signs) has been replaced by “acute respiratory infections” (ARI, defined as sudden onset of fever or feeling of fever and respiratory signs).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

  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 (2022w25), the incidence rate of ARI cases consulting in general practice was estimated at 110 cases per 100,000 inhabitants (95% CI [95 ; 125]). This rate is increasing compared to week 2022w24 (consolidated data: 80 [70 ; 90]).

At the regional level, the highest incidence rates were noted in: Provence-Alpes-Côte d’Azur (277 [146 ; 408]), Bretagne (195 [114 ; 276]) and Centre-Val de Loire (142 [67 ; 217]).

COVID-19: the incidence of ARIs due to COVID-19 seen in general practice (52 cases per 100,000 population (95% CI [43; 61])) is increasing compared to the previous week 2022w24.

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 (2022w25), the incidence rate of acute diarrhea cases seen in general practice was estimated at 67 cases per 100,000 inhabitants (95% CI [54 ; 80]). This rate is stable compared to week 2022w24 (consolidated data: 55 [46 ; 64]) and at a lower level of activity than those usually observed in this period.

At the regional level, the highest incidence rates were noted in: Nouvelle-Aquitaine (108 [44 ; 172]), Grand Est (107 [50 ; 164]) and Corse (83 [0 ; 184]).
