Untreatable Mosquito Bug Hits Travelers: CDC Issues Warnings

U.S. health authorities have alerted travelers to potential risks in several tropical destinations. The Centers for Disease Control and Prevention (CDC) has issued Level 2 travel advisories for Cuba, Bangladesh, Sri Lanka, and China's Guangdong Province, urging enhanced precautions against chikungunya.

This mosquito-borne illness is currently untreatable but can be prevented with a vaccine. Common symptoms include fever and debilitating joint pain, which can persist for months. Between January and September 2025, the world saw an alarming 445,000 suspected and confirmed cases, resulting in 155 fatalities, according to the World Health Organization.

Significant outbreaks have been noted, with Guangdong Province reporting its largest-ever documented outbreak. While specific case numbers vary by location, the CDC also highlights an increased risk in other countries like India and Mexico, even without reported outbreaks.
