  • Contribute to informing and raising awareness among healthcare professionals, local authorities, and the general public about the disease and preventive measures.

Global Data

The virus is present on all five continents and is endemic in tropical and intertropical regions. Since 2004, outbreaks have become increasingly frequent and have spread to temperate regions (Europe). A major outbreak affected the Indian Ocean, particularly Réunion and Mayotte, in 2006. The virus also severely affected the Americas, including the French overseas departments in the Americas, beginning in 2013. By the end of 2024, indigenous transmission of the virus had been documented in approximately 119 countries. More recently, the chikungunya virus circulated in Réunion in 2025, with nearly 55,000 confirmed cases and an estimated 400,000 cases based on a seroprevalence study.
