An outbreak of 4 autochthonous (locally transmitted) cases of dengue fever was detected in Gardanne in the department of Bouches-du-Rhône. Symptoms of the cases occurred between the second half of July and early August 2023.
At least 47 autochthonous cases were recorded in France in 2022. The affected regions were Occitania (9 cases) and Provence-Alpes-Cote d'Azur (36 cases).
Optimal mosquito protection especially during the day. In case of fever, take paracetamol preparations and ensure sufficient fluid intake. Do not take medications containing acetylsalicylic acid (e.g. Aspirin®), as these increase the risk of bleeding in the event of a dengue infection.
