To date, 5 cases have been identified have been identified in Saint Laurent du Var (Alpes-Maritimes) and two in Hérault.

Officials note that these two episodes of autochthonous transmission are not epidemiologically linked and the viruses are of different serotypes.

Epidemiological investigations have been set up to identify other possible cases and to strengthen prevention and surveillance measures. Health professionals in the two communes where the cases were identified were also made aware of the detection and reporting of other people with suspected dengue fever. Mosquito control operators immediately carried out entomological investigations and undertook targeted mosquito control activities.

Due to the identification of these two outbreaks of indigenous cases in the Alpes-Maritimes and Hérault, the two departments were placed in level 3 of the anti-dissemination plan of chikungunya and dengue in mainland France.

In addition to the 7 indigenous cases, France has also reported 172 imported cases to date in 2018.
