The U.S. Centers for Disease Control and Prevention has issued a travel warning following an outbreak of a mosquito-borne illness called chikungunya in China. The CDC's warning centers on Guangdong Province, where the outbreak has exceeded 7,000 confirmed cases since June 2025, according to Chinese health officials.

Summer 2025 brought a Chikungunya outbreak to China as cases of the mosquito-borne illness climbed, prompting Covid-19-like measures.

U.S. health officials are warning travelers headed to southern China of an outbreak of chikungunya, a mosquito-spread disease that spurred a forceful response.
