The U.S. Centers for Disease Control and Prevention (CDC) has issued a Level 2 Travel Health Notice for Sri Lanka, advising travelers to “practice enhanced precautions” due to an increase in cases of the mosquito-borne chikungunya virus.
The notice, released in December 2025, comes as Sri Lanka continues to grapple with the aftermath of Cyclone Ditwah, which caused widespread damage to infrastructure and placed additional strain on the country’s health services.
The CDC cautioned that conditions following heavy rainfall and flooding can increase mosquito breeding, heightening the risk of transmission. Travelers are advised to take preventive measures such as using insect repellent, wearing long-sleeved clothing, and staying in accommodations with proper mosquito control.
Chikungunya is spread by infected mosquitoes and typically causes fever and severe joint pain, though symptoms can vary. The CDC urged travelers to monitor their health closely during and after travel and to seek medical attention if symptoms develop.
