The Centers for Disease Control and Prevention (CDC) issued new travel health notices on December 5 following significant outbreaks in Bangladesh and Sri Lanka. The agency advised U.S. travelers heading to these destinations to adopt “enhanced precautions,” particularly measures that reduce mosquito exposure.
These latest alerts build on similar advisories released in recent months for China’s Guangdong Province and for Cuba, where health officials have also tracked increasing case numbers.
According to the World Health Organization, chikungunya outbreaks continue to occur primarily in the Americas, Asia, and Africa, with occasional smaller clusters detected in parts of Europe. While the disease is rarely fatal, there is currently no vaccine or antiviral treatment, making prevention—especially avoiding mosquito bites—the most effective protection for travelers.
The CDC continues to monitor global trends and encourages travelers to stay informed, use EPA-approved insect repellents, wear long sleeves and pants when possible, and seek medical attention if they develop symptoms after returning from affected areas.

Understanding Chikungunya: Key Facts About the Mosquito-Borne Virus
Chikungunya virus (CHIKV) is a mosquito-borne pathogen that continues to pose a significant public-health challenge in regions prone to Aedes mosquito activity. The disease, first identified in East Africa, is best known for its sudden onset of fever and intense joint pain—symptoms severe enough to cause the characteristic bent or stooped posture that gave the illness its name. “Chikungunya” originates from the Kimakonde word meaning “to bend up” or “to become contorted.”
The virus is transmitted primarily through the bites of infected female Aedes aegypti and Aedes albopictus mosquitoes, the same vectors responsible for Zika and dengue. Symptoms typically begin four to eight days after a bite and often include high fever, debilitating joint pain—especially in the hands and feet—headaches, muscle aches, swelling, rash, nausea, and fatigue. While the disease is rarely life-threatening, its joint pain can persist for months, significantly affecting quality of life.
Because no antiviral treatment or vaccine currently exists, management focuses on relieving discomfort with fever reducers, hydration, and supportive care. Public-health agencies emphasize prevention as the most effective protection against infection. This includes using insect repellents, wearing long sleeves and pants, sleeping in well-screened areas, and reducing mosquito breeding sites by eliminating standing water.
As outbreaks continue to emerge in parts of Asia, Africa, and the Americas—with occasional clusters in Europe—global health authorities urge travelers to remain vigilant, particularly when visiting regions experiencing active transmission.
