Our missions

  • Define, manage, and coordinate epidemiological surveillance of dengue fever in France

  • Adapting surveillance to regional specificities and risks: enhanced surveillance systems in metropolitan departments where the mosquito vector is present, and specific systems for the various overseas departments in collaboration with regional units linked to regional health agencies

  • Contribute to informing and raising awareness among healthcare professionals, local authorities, and the general public about the disease and preventive measures

data

The surveillance and prevention of the risk of dengue (and chikungunya) transmission are situated within a global epidemiological context.

The epidemiological profiles of dengue vary widely depending on the specific French territory in question. Thus,

  • The dengue virus is hyperendemic in the French departments of the Americas.

  • Small-scale outbreaks occurred sporadically in the Indian Ocean territories until 2017. In 2018 and 2019, a major outbreak struck the island of Réunion.

  • Limited episodes of local transmission are regularly identified in mainland France.

Les profils épidémiologiques de la dengue sont très variés selon le territoire français considéré. Ainsi,

  • Le virus de la dengue est hyper-endémique dans les départements français d’Amérique.
  • Des épidémies de faible ampleur ont sévi irrégulièrement dans les territoires de l’Océan Indien jusqu’en 2017. En 2018 et 2019 une épidémie importante atteint l’île de la Réunion.
  • Des épisodes limités de transmission locale sont régulièrement identifiés en métropole.
