Abstract

In 2025, a large outbreak of chikungunya occurred in Réunion Island (France). By 10 July, 1,911 imported cases were notified in Mainland France, most (89%) were associated with travel to Réunion Island. Ten autochthonous outbreaks in five French regions involving 27 cases were identified between May and mid-July and outbreaks occurred earlier than in previous years. the mosquito vector, is endemic in large parts of France. Transmission events early in the vector active season is concerning.
