Ten cases of dengue fever have been detected in people living in Sainte-Cécile-les-Vignes, in Vaucluse, the ARS Provence-Alpes-Côte d’Azur announced in a press release on Thursday, August 22. “The declaration of a first case of dengue fever by a health professional on August 14 allowed the Provence-Alpes-Côte d’Azur regional health agency to identify in the same district of this municipality the case of imported dengue fever and several [neuf] indigenous cases”.

The ARS specifies that to prevent the spread of the disease, “mosquito control was carried out in the municipality […] on public roads and in private gardens”.

On Wednesday, an indigenous case of dengue fever was detected in Montélimar, in the Drôme, and made official by the Auvergne-Rhône-Alpes regional health agency. This was the seventh indigenous case in mainland France this year. With the nine new cases, the figure now rises to 16 indigenous cases.

The first indigenous case of the year in mainland France was made official on Monday, July 8 in Hérault. Regarding imported cases of dengue, Public Health France recorded 1,031 from May 1 to August 13, 2024.

As a reminder, we speak of an indigenous case when a person has contracted the disease in metropolitan France and has not traveled to a contaminated area in the 15 days preceding the onset of symptoms. Dengue is a viral disease transmitted by mosquitoes to humans, most often benign, which can develop, in approximately 1% of cases, into a more serious form causing bleeding in particular. Deaths are very rare.
