Northeast France Reports Local Chikungunya Case

The regional health agency in Grand Est, France, reported its first locally acquired case of chikungunya in Bas-Rhin.
As of July 1, 2025, epidemiological investigations indicated that this locally acquired chikungunya case had frequented the municipalities of Lipsheim and Fegersheim during their infectious period.
Unlike previous local cases, this area is located in France's northeast.
In June 2025, Occitane (Hérault and Gard), Provence-Alpes-Côte d'Azur (Var and Bouches-du-Rhône), Auvergne-Rhône-Alpes (Drôme), and the island of Corse (Corse-du-Sud) reported local chikungunya cases.
And in the southern Indian Ocean, France's departments have reported significant chikungunya outbreaks in 2025.
According to the World Health Organization and the United States, chikungunya is a vaccine-preventable disease, with two vaccines commercially available as of July 2025.
