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 (2024w46), the incidence rate of acute respiratory infection (ARI) cases consulting in general practice was estimated at 153 cases per 100,000 population (95% CI [146; 159]) (data sources: Sentinelles and IQVIA (EMR)).
Subject to future data consolidation, this rate was stable compared to the previous week (data consolidated for 2024w45: 161 [154; 167]). However, there has been an increase in children, particularly in the 0-4 age group.

At the regional level, the highest incidence rates were noted in: Bretagne (214 [173; 255]), Grand Est (199 [173; 225]) and Hauts-de-France (177 [155; 199]).

Covid-19: the incidence rate of Covid-19 cases seen in general practice for an ARI was estimated at 19 cases of Covid-19 per 100,000 population (95% CI [15; 23]), (data source: Sentinelles).
Subject to future data consolidation, this rate was stable in all age groups compared to the previous week (data consolidated for 2024w45: 17 [13; 22]). Nevertheless, SARS-CoV-2 is still circulating actively.

RSV: the incidence rate of RSV cases seen in general practice for an ARI was estimated at 26 RSV cases seen in general practice per 100,000 population (95% CI [19; 33]) (data sources: Sentinelles, SOS Médecins, Rouen and Côte d’Azur Universities).
Subject to future data consolidation, this rate was increasing in the 0-14 age group and stable in the 15 and above age group compared to the previous week (data consolidated for 2024w45: 9 [5; 12]).

Bronchiolitis in children under 2: the incidence rate of bronchiolitis cases in children under 2 seen in general practice was estimated at 159 cases per 100,000 population (95% CI [111; 207]) (data source: IQVIA (EMR)).
Subject to future data consolidation, this rate was slightlyincreasing compared to the previous week (data consolidated for 2024w45: 139 [91; 187]). The level of bronchiolitis activity in this age group is lower than that usually observed at this time of the year.

Influenza: the incidence rate of influenza cases seen in general practice for an ARI was estimated at 13 influenza cases per 100,000 population (95% CI [8; 18]) (data sources: Sentinelles, SOS Médecins, Rouen and Côte d’Azur Universities).
Subject to future data consolidation, this rate was slightly increasing, particularly among 0-14 age group compared to the previous week. The circulation of influenza viruses is increasing in primary care.

The purpose of acute diarrhea surveillance is to monitor gastroenteritis outbreaks. 

In mainland France, last week (2024w46), the incidence rate of acute diarrhea cases seen in general practice was estimated at 48 cases per 100,000 population (95% CI [44; 51]). 
Subject to future data consolidation, this rate is stable compared to the previous week (consolidated data for 2024w45: 53 [50; 57]) and corresponds to a lower activity level than those usually observed at this time of the year.

At the regional level, the highest incidence rates were noted in: Bretagne (71 [47; 96]), Grand Est (69 [52; 86]) and Hauts-de-France (65 [51; 79]).

In mainland France, last week (2024w46), the incidence rate of Chickenpox cases seen in general practice was estimated at 4 cases per 100,000 population (95% CI [3; 5]). 
Subject to future data consolidation, this rate is stable compared to the previous week (consolidated data for 2024w45: 5 [4; 6]) and corresponds to a lower level of activity than those usually observed at this time of the year.

At the regional level, the highest incidence rates were noted in: Corse (7 [0; 21]), Centre-Val de Loire (6 [1; 12]) and Hauts-de-France (6 [2; 10]).
