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illness” (ILI, defined as sudden onset of fever above 39°C, accompanied by myalgia and respiratory signs) has been replaced by “acute respiratory infections” (ARI, defined as sudden onset of fever or feeling of fever and respiratory signs).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

  Increasing 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 (2021w29), the incidence rate of ARI consultating (or teleconsulting) in general practice was estimated at 59 cases per 100,000 inhabitants (95% CI [47 ; 71]). This rate is increasing compared to week 2021w28 (consolidated data: 37 [28 ; 46]).

At the regional level, the highest incidence rates were noted in: Nouvelle-Aquitaine (127 [65 ; 189]), Bretagne (79 [17 ; 141]) and Provence-Alpes-Côte d’Azur (78 [13 ; 143]).

COVID-19 monitoring: Last week (2021w29), the SARS-CoV-2 positivity rate of patients consulting for ARI was 12%, 34% and 20%, 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 16 cases per 100,000 population (95% CI [11; 20]), corresponding to 10,245 [7,053; 13,437] new cases of COVID-19 seen in general practice. This rate is significantly increasing compared to the previous week (consolidated data for 2021w28 : 4 [3; 6]) representing 2,818 [1,859; 3,777] new ARI cases due to COVID-19 seen in general practice).

Acute diarrhea   Définition

  Low activity in general practice

Previously on sentiweb            

 
In metropolitan France, last week (2021w29), the incidence rate of acute diarrhea seen in general practice was estimated at 75 cases per 100,000 inhabitants (95% CI [60 ; 90]). This rate is slightly increasing compared to week 2021w28 (consolidated data: 65 [54 ; 76]) with a similar activity level compared to those usually observed in this period.

At the regional level, the highest incidence rates were noted in: Hauts-de-France (103 [38 ; 168]), Pays de la Loire (103 [29 ; 177]), Bourgogne-Franche-Comté (77 [16 ; 138]) and Provence-Alpes-Côte d’Azur (73 [13 ; 133]).
