Warning

COVID-19, Influenza Surveillance conducted by the Sentinelles network

In March 2020, following the emergence of SARS-CoV-2 (Covid-19), Sentinelles surveillance evolved.The monitoring of "influenza-like illness" (sudden onset of fever > 39°C (>102°F) with myalgia and respiratory signs) has been replaced by that of "acute respiratory infections" (ARI) (sudden onset of fever (or feeling of fever) and respiratory signs).The surveillance of this new health indicator allows monitoring the evolution of the COVID-19 pandemic, as well as epidemics caused by other respiratory viruses (influenza, RSV, rhinovirus and metapneumovirus).This surveillance is conducted in collaboration with “Santé publique France”, the National Reference Center for respiratory infections (“Institut Pasteur “and “Hospices Civils de Lyon”) and the University of Corsica.

The weekly reports of “Santé publique France” include all the surveillance data (outpatient and hospital) on the situation regarding COVID-19 and influenza.

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

  Stable activity in general practice

Previously on sentiweb            

The objective of ARI surveillance is to monitor epidemics of COVID-19, INFLUENZA as well as those due to other seasonal respiratory viruses (RSV, rhinovirus and metapneumovirus).

In metropolitan France, last week (2021w23), the incidence rate of ARI consultating (or teleconsulting) in general practice was estimated at 31 cases per 100,000 inhabitants (95% CI [24 ; 38]). This rate is stable compared to week 2021w22 (consolidated data: 33 [27 ; 39]).

At the regional level, the highest incidence rates were noted in: Bourgogne-Franche-Comté (57 [1 ; 113]), Grand Est (43 [0 ; 86]) and Ile-de-France (38 [15 ; 61]).

COVID-19 monitoring: Last week (2021w23), the SARS-CoV-2 positivity rate of patients consulting for ARI was 0%, 11% and 11%, respectively in the 0-14, 15-64, and 65 and older age groups.
 the incidence rate of ARI cases due to SARS-CoV-2 (COVID-19) seen in general practice was estimated at 3 cases per 100,000 population (95% CI [1; 4]), corresponding to 1,758 [959; 2,557] new cases of COVID-19 seen in general practice. This rate is stable compared to the previous week (consolidated data for 2021w22 : 3 [2; 4]. This represents 2,199 [1,445; 2,953] new cases of ARI due to COVID-19 seen in general practice).

INFLUENZA monitoring: there is no active circulation of influenza viruses in GPs and paediatric consultations. Last week (2021w23), no influenza virus was detected.

Other respiratory viruses monitoring : rhinovirus circulation in week 2021w23.
