Semaine 202504 - Acute Respiratory Infection (ARI) - High activity in general practice

Monday 20 Jan 2025

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 (2025w04), the incidence rate of acute respiratory infection (ARI) cases consulting in general practice was estimated at 716 cases per 100,000 population (95% CI [684; 747]) (Data sources: Sentinelles and Electronic Medical Records (EMR) IQVIA)).
Subject to future data consolidation, this rate is strongly increasing compared to the previous week and is at a very high level of activity (consolidated data for 2025w03: 495 [471; 519]).

At the regional level, the highest incidence rates were noted in: Bretagne (1,269 [1,093 ; 1,445]), Provence-Alpes-Côte d'Azur (1,168 [929 ; 1,407]) and Corse (882 [646 ; 1,118]). 

Influenza: the incidence rate of influenza cases seen in general practice for an ARI was estimated at 422 cases per 100,000 population (95% CI [381; 463]), corresponding to 282,643 [255,069; 310,217] new cases (data sources: Sentinelles, SOS Médecins, DUMG Rouen and DERMG Côte d'Azur).
Subject to future data consolidation, this rate is strongly increasing compared to the previous week reaching a high level of intensity (consolidated data for 2025w03: 247 [223; 271]). Among children (0-15 age group), the incidence rate is continuing the rise seen over the last three weeks. Among adults (aged 15 and over), the increase has resumed, after appearing to stabilise in recent weeks.

RSV infection: the incidence rate of RSV infection cases seen in general practice for an ARI was estimated at 45 cases per 100,000 population (95% CI [29; 61]), corresponding to 30,415 [19,751; 41,079] new cases (data sources: Sentinelles, SOS Médecins, Rouen and Côte d'Azur Universities).
Subject to future data consolidation, this rate is increasing compared to the previous week and remained at a high level for the period (consolidated data for 2025w03: 27 [18; 37]).

Bronchiolitis in children under 2: data from week 2025w01 to 2025w04 are currently not available (source: IQVIA (EMR)).

Covid-19: the incidence rate of Covid-19 cases seen in general practice for acute respiratory infection was estimated at 10 cases  100,000 population (95% CI [8; 12]), corresponding to 6,625 [5,064; 8,186] new cases (data source: Sentinelles).
Subject to future data consolidation, this rate is stable compared to the previous week and is still at a low level of activity (consolidated data for 2025w03: 8 [7; 10], corresponding to 5,669 [4,407; 6,931] new cases).

Semaine 202504 - Acute diarrhea - Moderate activity in general practice

Monday 20 Jan 2025

The purpose of acute diarrhea surveillance is to monitor gastroenteritis outbreaks.
 
In mainland France, last week (2025w04), the incidence rate of acute diarrhea cases seen in general practice was estimated at 119 cases per 100,000 population (95% CI [105; 132]). 
Subject to future data consolidation, this rate continues the increase observed over the last few weeks and is at a similar activity level than those usually observed during this period (consolidated data for 2025w03: 99 [87; 111]).

At the regional level, the highest incidence rates were noted in: Grand Est (184 [131; 237]), Provence-Alpes-Côte d'Azur (183 [94; 273]), Nouvelle-Aquitaine (141 [85; 197]) and Hauts-de-France (141 [96; 186]).

Semaine 202504 - Chickenpox - Low activity in general practice

Monday 20 Jan 2025

In mainland France, last week (2025w04), the incidence rate of Chickenpox cases seen in general practice was estimated at 13 cases per 100,000 population (95% CI [8; 18]). 
Subject to future data consolidation, this rate is increasing compared to the previous week but remains at a lower level of activity than those usually observed during this period (consolidated data for 2025w03: 4 [2; 6]).

At the regional level, the highest incidence rates were noted in: Provence-Alpes-Côte d'Azur (45 [14; 76]), Bourgogne-Franche-Comté (25 [5; 46]) and Auvergne-Rhône-Alpes (15 [3; 27]).
