From 00:00 on September 14, 2025, to 24:00 on September 20, 2025, a total of 2,426 new locally transmitted cases of chikungunya fever were reported across Guangdong Province, with no severe or fatal cases noted. Among them, Jiangmen City accounted for 2,238 cases, making it the most severely affected area in the province during this period.
Foshan recorded 81 cases, while Guangzhou saw 47 cases. Shenzhen reported 12 cases, and Zhuhai and Zhanjiang each registered 7 cases. Zhongshan had 6 cases, while Shaoguan and Dongguan reported 5 cases each. Qingyuan accounted for 4 cases, whereas Shantou, Zhaoqing, and Chaozhou each reported 3 cases. Maoming, Huizhou, Meizhou, Yangjiang, and Jieyang reported 1 case each.
Kang Min, director of the Institute for Prevention and Control of Infectious Diseases at the Guangdong Provincial Center for Disease Control and Prevention, stated that the recent increase in chikungunya fever cases in Jiangmen City has prompted the local government to initiate a Level III public health emergency response, mobilizing all available resources to curb the spread of the disease.
Kang emphasized that Guangdong remains in the peak season for mosquito activity from September to October. The combination of typhoons, rainfall, and increased population mobility due to the upcoming Mid-Autumn Festival and National Day holidays heightens the risk of further transmission of chikungunya fever. Therefore, disease prevention and control efforts will remain stringent.
Chikungunya fever is primarily transmitted through the bite of infected Aedes mosquitoes (commonly known as "tiger mosquitoes"), which prefer to breed in small, clean standing water sources.
Kang stressed that the foundation for controlling the spread of the disease lies in eliminating stagnant water, killing adult mosquitoes, and preventing mosquito bites.
