Open Outbreak

Dengue in France

Pathogen: dengue · Region: Metropolitan France · Status: monitoring · Tier: moderate · Updated

Metropolitan France is monitoring locally acquired dengue in 2026. The outbreak brief provided for this record says the national bulletin has reported autochthonous episodes in metropolitan France, including at least one local episode in Dordogne, and that at least one episode has already been declared closed. That means the event is not just imported travel-associated dengue: some local mosquito-borne transmission has occurred inside metropolitan France. What remains unclear is the scale. No official case counts, department-by-department totals, serotypes, or detailed control measures were retrieved in this session, and Outbreak Tracker had no collected reports yet for this outbreak. WHO search results did not show a Disease Outbreak News item specifically about metropolitan France dengue, so there is no WHO event-level assessment to rely on here. Media retrieval also failed, so there is no solid recent media count to compare with the official account. The main risk signal is epidemiological rather than clinical: dengue is a known mosquito-borne disease, but local transmission in metropolitan France is unusual and depends on competent Aedes vectors, likely Aedes albopictus. The main things to watch are whether additional departments report autochthonous episodes, whether any active transmission continues late into autumn, whether episode counts are rising, and whether authorities describe these events as isolated introductions or a broader seasonal pattern.

The main concern is not efficient human-to-human spread but repeated local mosquito-borne transmission in a highly connected country during vector season. Risk stays moderated by the usually low overall fatality profile and the apparent absence of explosive growth in the retrieved material, but uncertainty remains because this session did not retrieve the current French bulletin with exact counts and locations.

Situation as of 20 Oct 2026

Official

The outbreak record notes that the national bulletin has reported autochthonous dengue episodes in metropolitan France, including at least one local episode in Dordogne, and that at least one episode is already closed. No official numerical total was retrieved in this session.

Media, unverified

No reliable recent media account was retrievable in this session because news searches failed, so no separate media figure can be stated.

Control measures

The record indicates active national monitoring and closure of at least one episode, but specific measures such as vector control, screening radius, or public advisories were not retrieved in this session.
