As of late April 2026, several regions in France have reported an increase in gastroenteritis-like symptoms, including acute diarrhea, vomiting, fever, and fatigue. This rise is notable because spring typically sees a decline in winter infections. However, health authorities have not confirmed any alarming evolution.
According to data from SantΓ© publique France, the incidence rate of acute diarrhea in community settings has slightly exceeded the seasonal baseline for this time of year. For the week ending April 26, 2026, the rate was 145 cases per 100,000 inhabitants, compared to the seasonal threshold of 120. This is below the epidemic threshold of 200 cases per 100,000.
Experts attribute the increase to the circulation of norovirus and rotavirus, which can persist into spring. No new or more virulent strains have been identified. The symptoms are generally self-limiting, lasting 1 to 3 days, and treatment focuses on hydration and rest.
Health officials recommend standard hygiene measures: frequent hand washing, avoiding shared utensils, and staying home if symptomatic. Vulnerable populations, such as the elderly and young children, should seek medical advice if symptoms persist.
In summary, while there is a slight uptick in gastroenteritis cases, it does not represent an unusual or concerning public health event. Monitoring continues.
