The number of indigenous cases of dengue, designating people infected locally without having recently traveled to an area where the virus circulates, increased in one week in France, from 57 to 68 cases, according to Public Health France.
It is in the municipalities of La Crau, Sainte-Cécile-les-Vignes and Fréjus, all located in the Provence-Alpes-Côte d’Azur region (south-east of France), that the greatest number of indigenous cases was listed, respectively 25, 18 and 11, according to the latest data from the French health agency.
Episodes of this virus are, moreover, still ongoing in Vendargues (Hérault), Sainte-Cécile-les-Vignes (Vaucluse), La Crau (Var), Fréjus (Var) and Vallauris (Alpes-Maritimes), specifies the same source.
Dengue fever, which is transmitted through the bite of infected tiger mosquitoes, is a generally mild but temporarily disabling disease.
The detection of a case of dengue gives rise to epidemiological and entomological investigations “to quickly trigger vector control measures and thus limit the risk of local transmission of the virus”, explains Public Health France.
When an indigenous case is identified, “vector control measures are reinforced with the carrying out of two adulticide mosquito control treatments in a wider area (300 m)”, continues the agency, noting that an “active search for cases is also implemented around the centers of indigenous cases”.
