Every year, an increase in acute gastroenteritis (AGE) is observed caused mainly by the circulation of noroviruses and rotaviruses. Noroviruses are responsible for AGE in people of all ages, while rotaviruses mainly affect children under 5 years of age.
During the winter season, Public Health France monitors, with its network of partners , the epidemiological evolution of acute gastroenteritis and publishes weekly national and regional epidemiological bulletins on its website . These data are also made available as open data on Géodes .
Santé publique France is today publishing the winter monitoring report covering the 2020-2021 and 2021-2022 seasons in mainland France and recalls the simple actions to take to limit the risk of contamination.
What are the highlights of the last two seasons?
2020-2021: a season marked by a historically low level of activity
The low level of activity observed from March 2020 (end of the 2019-2020 season), in the context of the COVID-19 pandemic, continued during the 2020-2021 season. In city medicine or in hospital emergency departments, activity remained relatively stable and lower than the years prior to the COVID-19 pandemic in all metropolitan areas.
A return to activity comparable to pre-COVID seasons during winter 2021-2022
The activity levels recorded throughout the 2021-2022 season were again comparable to those observed during the pre-COVID seasons. In hospital emergencies, activity for acute gastroenteritis remained close to historical maximums, from December 2021 to April 2022. Consultations at SOS Médecins were similar to the data observed before the COVID-19 pandemic.
