Overview

• Santé publique France has confirmed seven autochthonous chikungunya episodes in five regions this year, including the first ever in Grand Est after a Lipsheim resident was infected on June 27
• The Agence régionale de santé will carry out two mosquito-control operations in Lipsheim and Fegersheim on the nights of July 1–2 and July 8 to prevent further local spread
• Since early May, 712 imported cases from La Réunion and other Indian Ocean territories have been recorded, seeding an unprecedented early-season wave of local chikungunya infections
• High temperatures driven by climate change are boosting Aedes albopictus activity, with the tiger mosquito now established in at least 81 departments across metropolitan France
• With no antiviral treatment available, health authorities are relying on targeted vector control and personal protective measures to limit transmission
