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.

An outbreak of the chikungunya virus in China has prompted authorities to take preventive measures from mosquito nets and clouds of disinfectant, threatening fines for people who fail to disperse standing water and even deploying drones to hunt down insect breeding grounds.

Mosquito-borne chikungunya virus has caused an outbreak in China, but public health experts say the risk for spread and infection in U.S. remains low.

The mosquito-borne virus, first identified in Tanzania in 1952, causes fever, joint pain, headache, muscle pain, rash, and joint swelling, with symptoms typically appearing three to seven days after a bite from an infected mosquito.
