Italy Confirms First Local Dengue and Chikungunya Cases in Emilia-Romagna

The WHO has called for urgent vector control with boosted surveillance to curb domestic dengue and chikungunya transmissions.

Overview

  • Italy’s Emilia-Romagna region recorded its first home-grown dengue and chikungunya cases of 2025 alongside 82 imported dengue and 50 imported chikungunya infections nationwide.
  • The World Health Organization issued an urgent global alert this week warning of a potential chikungunya epidemic and urging coordinated mosquito-control measures.
  • Since May 1, continental France has reported around 800 imported chikungunya cases and 12 locally transmitted infections, and Italy has now confirmed domestic transmission in Emilia-Romagna.
  • Foshan city in Guangdong province is battling China’s worst chikungunya outbreak in twenty years, with over 3,100 cases reported so far in July.
  • Health experts attribute the resurgence to rising temperatures, expanded Aedes mosquito habitats and increased international travel in the absence of specific chikungunya vaccines.
