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 (2024w43), the incidence rate of acute respiratory infection (ARI) cases consulting in general practice was estimated at 183 cases per 100,000 population (95% CI [175; 190]) (Data source: Sentinelles and IQVIA (EMR)).
Subject to future data consolidation, this rate is decreasing compared to the previous week (consolidated data for 2024w42: 207 [199; 215]).

At the regional level, the highest incidence rates were noted in: Grand Est (310 [272; 347]), Bretagne (262 [210; 314]) and Nouvelle-Aquitaine (187 [155; 219]). 

Covid-19: the incidence rate of Covid-19 cases seen in general practice for an ARI was estimated at 27 cases per 100,000 population (95% CI [22; 32]) (Data source: Sentinelles).
Subject to future data consolidation, this incidence rate is decreasing compared to the previous week (consolidated data for 2024w42: 42 [37; 47]). The incidence rates were decreasing in the 15-64 and 65 and above age groups, and stable in the 0-14 age group compared to the previous week. 

RSV: the incidence rate of RSV cases seen in general practice for an ARI was estimated at 0 cases per 100,000 population (95% CI [0; 8]) (Data sources: Sentinelles, Rouen and Côte d’Azur Universities, SOS Médecins).
Subject to future data consolidation, this rate is stable compared to the previous week. No active circulation of RSV is observed for now in primary care. This level of activity was lower than the ones observed in the last two seasons at the same time, but similar to previous seasons.

Influenza: the incidence rate of influenza cases seen in general practice for an ARI was estimated at 2 cases per 100,000 population (95% CI [0; 4]) (Data sources: Sentinelles, Rouen and Côte d’Azur DUMG, SOS Médecins). 
Subject to future data consolidation, this rate is stable compared to the previous week. No active circulation of influenza viruses is observed for now in primary care. This level of activity is similar to past seasons at the same time of the year.

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

In mainland France, last week (2024w43), the incidence rate of acute diarrhea cases seen in general practice was estimated at 49 cases per 100,000 population (95% CI [45; 54]). 
Subject to future data consolidation, this rate is slightly decreasing compared to the previous week (consolidated data for 2024w42: 60 [55; 64]) 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: Provence-Alpes-Côte d’Azur (87 [67; 108]), Nouvelle-Aquitaine (71 [52; 89]) and Bretagne (69 [43; 95]).

In mainland France, last week (2024w43), the incidence rate of Chickenpox cases seen in general practice was estimated at 7 cases per 100,000 population (95% CI [5 ; 8]). 
Subject to future data consolidation, this rate is slightly increasing compared to the previous week (consolidated data for 2024w42: 5 [4; 7]) 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: Pays de la Loire (14 [1; 27]), Provence-Alpes-Côte d’Azur (12 [4; 19]) and Hauts-de-France (9 [3; 15]).
