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.

 
In metropolitan France, last week (2021w23), the incidence rate of Chickenpox seen in general practice was estimated at 15 cases per 100,000 inhabitants (95% CI [10 ; 20]). This rate is increasing compared to week 2021w22 (consolidated data: 7 [4 ; 10]) with an activity level below those usually observed in this period.

At the regional level, the highest incidence rates were noted in: Pays de la Loire (46 [0 ; 96]), Nouvelle-Aquitaine (25 [3 ; 47]) and Centre-Val de Loire (24 [0 ; 48]).

 
In metropolitan France, last week (2021w23), the incidence rate of acute diarrhea seen in general practice was estimated at 70 cases per 100,000 inhabitants (95% CI [58 ; 82]). This rate is slightly increasing compared to week 2021w22 (consolidated data: 53 [45 ; 61])  and similar to the levels usually observed in this period.

At the regional level, the highest incidence rates were noted in: Hauts-de-France (91 [44 ; 138]), Grand Est (88 [28 ; 148]) and Pays de la Loire (76 [19 ; 133]).
