In 2020, four outbreaks of indigenous dengue have already been identified.

The number of cases of dengue, zika and chikungunya has doubled in metropolitan France in one year, Public Health France said on Tuesday, September 15, according to franceinfo. If a majority of these cases are “imported” from abroad, the progression of the implantation of the tiger mosquito, which carries these diseases, plays an important role in the contaminations.

The tiger mosquito is now present in 58 metropolitan departments, recalls franceinfo. The southern half of the territory, but also Alsace and part of the Paris region are concerned.

In 2019, 920 cases of dengue, 110 cases of chikungunya and 17 cases of zika were reported by doctors in mainland France, twice as many as the previous year. A large part of these cases are said to be “imported”: they concern people infected abroad, in Africa, Asia, South America, and who are diagnosed upon their return to France. But some are so-called “indigenous” cases. These are people who have not left the national territory, but who have been contaminated by tiger mosquitoes. who had previously stung “imported” cases.

Thus, Public Health France identified in 2019 several outbreaks of dengue fever in Auvergne-Rhône-Alpes and PACA, or zika in the Var.

In 2020, the organization has already identified two indigenous foci of dengue in Nice (Alpes-Maritimes), one in Croix-Valmer (Var) and another in Hérault. These reports lead to investigations and mosquito control operations in the areas concerned.
