The virus is transmitted by infected mosquitoes, so China is using giant "compulsive killers", known as elephant mosquitoes, whose larvae "devour" the Aedes mosquito, which passes chikungunya to people, said The Telegraph.

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.
