Overview

• The case in La Crau, Var, marks the first local chikungunya infection in metropolitan France this year and involved a patient without recent travel to known outbreak zones.
• ARS Paca has enlisted EID-Med teams to spray public areas and private gardens around the patient’s neighborhood to eliminate mosquito breeding sites.
• Door-to-door investigations by ARS Paca and Santé publique France will identify symptomatic residents and provide guidance on prevention.
• This development follows a major chikungunya outbreak on Réunion Island, which has tallied about 200,000 cases and 23 deaths since August 2024.
• Mayotte continues to report local transmission with 746 cases recorded in 2025, suggesting persistent risk in the French Indian Ocean territories.
