Should I be worried about Dengue in France?
- If you are in the affected area no assessment
- No agency has published an assessment for people in the affected area in metropolitan France. No French dengue bulletin with a risk level was retrievable.
- If you are elsewhere in the same country or region no assessment
- No agency has published an assessment for people elsewhere in France. No French dengue bulletin with a risk level was retrievable.
- If you are travelling there soon no assessment
- No agency has published an assessment for travellers to metropolitan France. No dengue-specific travel notice with a risk level was retrievable.
- If you are elsewhere in the world high
- WHO assessed the global risk from dengue as high in its global situation updates on 21 December 2023 and 30 May 2024. That is a global dengue assessment, not a France-specific one. According to WHO

What is happening
Metropolitan France is monitoring locally acquired dengue episodes in 2026, which is unusual in a non-endemic European setting. National surveillance has indicated autochthonous episodes in metropolitan France, including at least one in Dordogne. At least one episode has already been closed, but the retrieved documents did not provide the current number of confirmed cases or which departments besides Dordogne are affected. There are no current official figures in the retrieved documents, and no usable recent media count was retrieved either. Officials still need to clarify whether any transmission focus remains active and what mosquito-control, case-finding, and blood-safety measures are in force.

Who is affected and how it spreads
Dengue is a viral infection spread mainly through the bite of infected Aedes mosquitoes, especially Aedes aegypti and, to a lesser extent, Aedes albopictus. WHO describes dengue as most common in tropical and subtropical settings, but local transmission can appear in places with suitable mosquito vectors. Many infections cause no symptoms or only mild illness, but some people develop severe dengue. Infection with one dengue type does not give lasting protection against the others, which is one reason outbreaks can return.

What we are watching
- A French bulletin with current official counts of confirmed, probable, and suspected autochthonous cases.
- Whether departments beyond Dordogne have confirmed local transmission in 2026.
- Whether all reported metropolitan clusters are closed or any focus is still active.
- Any official detail on serotype, links to imported index cases, and local mosquito-control or blood-safety measures.
Updates
- · No substantive change since 16 October: there are still no retrievable current French official case figures or dengue-specific official risk assessments for metropolitan France, while WHO's global dengue assessment remains high for…
- · No clear change is documented since the previous update: France is still monitoring locally acquired dengue episodes, with no official case count published.
- · Figures, notices or the dossier were refreshed.
- · No new figures or French official bulletin URL were available since the previous version; WHO's high rating cited here applies only to the global dengue situation, not specifically to people in France or travellers to France.
- · The main change since the previous version is that the outbreak brief now indicates autochthonous dengue episodes in metropolitan France in 2026, including at least one in Dordogne and at least one episode already closed, while exact…
