Every month ECDC provides detailed epidemiological overview of the worldwide transmission of chikungunya virus disease in its weekly threat report (Communicable Diseases Threat Report).
The environmental conditions in most areas of the EU/EEA where Ae. albopictus or Ae. aegypti are established are now favourable for mosquito activity and virus replication in mosquitoes; therefore, locally acquired dengue cases may occur in the coming weeks.
Map
Since the start of 2026, and as of 5 August 2026 (data collection period 3–5 August, data available up to 28 July), 219 522 chikungunya virus disease (CHIKVD) cases and 81 associated deaths have been detected in 25 countries, excluding EU/EEA countries and territories.
