- 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.
