China is currently experiencing its largest outbreak of the chikungunya virus, a mosquito-borne disease that causes fever, joint pain, and rash but rarely leads to death. Since mid-June, nearly 8,000 people have been infected across at least 13 cities, with Guangdong province, particularly Foshan city, being the epicenter. Guangdong reported 1,387 new cases from August 3 to 9, a decline from nearly 3,000 weekly cases in previous weeks, indicating early success in containment efforts. Authorities have implemented various measures including mosquito control programs, insecticide spraying, public awareness campaigns, quarantine and isolation of patients, and the use of drones to combat the virus. The National Disease Control and Prevention Administration has issued technical guidelines for chikungunya prevention and control, designating South China's Guangxi Zhuang Autonomous Region as a Category I risk area. Despite the reduction in cases, health experts caution that vigilance must continue due to wet weather patterns that favor mosquito breeding. The outbreak has also raised concerns in neighboring regions such as Hong Kong and has prompted warnings about the virus potentially spreading to the United States.
