Cumulative cases since outbreak start — WHO DON bulletin dated 2025-10-03
Official report date — in isolated zones, field onset typically precedes this by days to weeks.
Between 1 January and 30 September 2025, a total of 445 271 suspected and confirmed CHIKV disease cases and 155 deaths were reported globally from 40 countries, including autochthonous and travel imported cases. Some WHO Regions are experiencing significant increases in case numbers compared to 2024, although others are currently reporting lower case numbers. This uneven distribution of cases across regions makes it challenging to characterize the situation as a global rise, however, given the ongoing outbreaks reported globally in 2025, the potential for further spread remains significant.
