Bangladesh Confirms Chikungunya Outbreak in Dhaka

The reappearance of 138 chikungunya cases in the People's Republic of Bangladesh in 2024 after a 7-year absence indicated the potential for larger outbreaks in the future.

In June 2025, the Institute of Epidemiology, Disease Control and Research in Bangladesh reported an outbreak of chikungunya in Dhaka city, with 337 cases reported between January and May 28, 2025.

Dhaka is the capital and largest city of Bangladesh. It is one of the largest and most densely populated cities in the world, with a population exceeding 10 million.

In addition to locals being at risk for this mosquito-transmitted virus, over 650,000 foreign visitors are expected to visit Bangladesh in 2025.

According to the U.S. CDC, travelers visiting areas with ongoing chikungunya outbreaks are at risk of infection. These health risk areas are constantly changing and evolving; therefore, travellers should check the latest information on outbreaks before departing abroad.

As of July 9, 2025, two new chikungunya vaccines have been approved for use in the United Kingdom, the European Union, and the United States. These vaccines are commercially offered at travel clinics and pharmacies in the U.S.
