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

  Moderate to high 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 (2023w47), the incidence rate of ARI cases consulting in general practice was estimated at 363 cases per 100,000 population (95% CI [337; 389]).
Subject to future consolidation of data, this rate is sharply increasing compared to the previous week (consolidated data for 2023w46: 258 [239; 277]).

At the regional level, the highest incidence rates were noted in: Grand Est (813 [638; 988]), Provence-Alpes-Côte d’Azur (489 [382; 596]) and Bretagne (465 [351; 579]). 

Covid-19: the incidence rate of Covid-19 cases seen in general practice for acute respiratory infection was estimated at 98 cases per 100,000 population (95% CI [79; 117]).
Subject to future data consolidation, this rate is increasing compared to the previous week (consolidated data for 2023w46: 69 [60; 78], corresponding to 45,872 [39,828; 51,916] new cases).
The incidence of Covid-19 cases presenting respiratory signs seen in general medical practice has been increasing since three weeks.

Influenza: a low circulation of influenza viruses was observed in general practice. This level of activity is similar to past seasons at the same period.

RSV: increase in the RSV circulation observed in general practice, and particularly among the 0-14 age group.
The level of RSV circulation 
observed in general practice was similar to the 2022-2023 season at the same time, but higher than the ones observed in previous seasons.

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 (2023w47), the incidence rate of acute diarrhea cases seen in general practice was estimated at 85 cases per 100,000 population (95% CI [70 ;100])
Subject to future consolidation of data, this rate is stable compared to the previous week (consolidated data for 2023w46: 73 [62 ;84]) and corresponds to a low activity level compared to those usually observed at this time of the year.

At the regional level, the highest incidence rates were noted in: Grand Est (159 [78; 240]), Nouvelle-Aquitaine (134 [85; 183]) and Occitanie (123 [76; 170]).

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.
