Health authorities in China’s Guangdong province reported 2,892 chikungunya infections between July 27 and Aug. 2, according to state-run Xinhua, with the bulk of cases concentrated in the manufacturing hub of Foshan. Officials said all patients exhibited mild symptoms and no deaths have been recorded so far. Local governments have stepped up vector-control efforts. In Foshan, mosquito-prevention messages are being broadcast on outdoor LED screens atop high-rise buildings and even on a Ferris wheel to encourage residents to limit exposure to the Aedes mosquitoes that spread the virus. The outbreak has already reached Hong Kong, where the Centre for Health Protection on Aug. 4 confirmed the city’s first chikungunya infection since 2019—a traveller recently returned from Foshan. While the case is considered imported, officials warned of the potential for local transmission and urged the public to remove standing water and use insect repellent.
