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 (2024w50), the incidence rate of acute respiratory infection (ARI) cases seen in general practice consultation was estimated at 348 cases per 100,000 population (95% CI [339; 358]) (data sources: Sentinelles and IQVIA (EMR)).
Subject to future data consolidation, this rate continues the increase observed since the beginning of November (2024w45) (consolidated data for 2024w49: 273 [265; 281]).

At the regional level, the highest incidence rates were noted in: Normandie (557 [505; 610]), Provence-Alpes-Côte d’Azur (452 [413; 491]) and Grand Est (449 [410; 488]).

RSV infection: the incidence rate of RSV infection cases seen in general practice among patients consulting for an ARI was estimated at 37 cases per 100,000 population (95% CI [27; 46]) (data sources: Sentinelles, SOS Médecins, Rouen and Côte d’Azur Universities).
Subject to future data consolidation, this rate is slightly decreasing compared to the previous week (consolidated data for 2024w49: 46 [37; 56]) but remains at a moderate level of activity.

Bronchiolitis in children under 2: the incidence rate of bronchiolitis cases in children under 2 seen in general practice was estimated at 472 cases per 100,000 population (95% CI [384; 560]) (data source: IQVIA (EMR)).
Subject to future data consolidation, this rate is stable compared to the previous week (data consolidated for 2024w49: 485 [397; 573]).

Influenza: the incidence rate of influenza cases seen in general practice among patients consulting for an ARI was estimated at 83 influenza cases per 100,000 population (95% CI [67; 100]) (data sources: Sentinelles, SOS Médecins, DUMG Rouen and DERMG Côte d’Azur).
Subject to future data consolidation, this rate is moderately increasing compared to the previous week (consolidated data for 2024w49: 70 [58; 82]).

Covid-19: the incidence rate of Covid-19 cases seen in general practice among patients consulting for an ARI was estimated at 19 cases per 100,000 population (95% CI [15; 23]) (data source: Sentinelles).
Subject to future data consolidation, this rate is stable compared to the previous week (consolidated data for 2024w49: 19 [16; 23]).

The purpose of acute diarrhea surveillance is to monitor gastroenteritis outbreaks.
 
In mainland France, last week (2024w50), the incidence rate of acute diarrhea cases seen in general practice was estimated at 72 cases per 100,000 population (95% CI [68; 76]). 
Subject to future data consolidation, this rate is slightly increasing since early November (2024w45) (consolidated data for 2024w49: 69 [65; 73]), but remains at a lower level of activity than those usually observed during this period.

At the regional level, the highest incidence rates were noted in: Grand Est (112 [93; 131]), Hauts-de-France (93 [76; 109]) and Bretagne (71 [50; 92]).

In mainland France, last week (2024w50), the incidence rate of Chickenpox cases seen in general practice was estimated at 8 cases per 100,000 population (95% CI [7; 10]). 
Subject to future data consolidation, this rate is slightly increasing since two weeks(consolidated data for 2024w49: 7 [6; 9]) but remains at a lower level of activity than those usually observed during this period.

(*) In order to compare trends observed between pre-COVID-19 and post-COVID-19 periods, data collected between week 01 of 2016 (2016w01) and up to 2020w11 (start date of the pandemic) are shown in the grey area (pre-COVID-19 seasons). The 2019-2020 season (from week 2020w12) and subsequent seasons are represented by distinct curves in blue (post-COVID-19 seasons). The current season is shown in red.
