China is confronting its largest outbreak of chikungunya fever, a mosquito-borne viral disease, primarily in Guangdong Province. Since mid-June, nearly 8,000 people have fallen ill, with over 7,000 cases reported since July, predominantly in Foshan city. Authorities have implemented extensive containment measures including drone surveillance, mosquito nets, chemical spraying, deployment of mosquito-eating fish, and quarantine protocols. These efforts have led to a decline in new cases, with weekly infections dropping from nearly 3,000 to 1,387 in early August. Foshan officials report that over 90% of patients have recovered. The outbreak has prompted the United States Centers for Disease Control and Prevention to issue a Level 2 travel advisory for China. Hong Kong has recorded several imported cases and launched a mosquito prevention campaign in response to rising regional infections. Chinese health authorities have introduced a four-tier risk classification system for infectious disease outbreaks to better manage public health risks. Despite the outbreak, experts in the U.S. consider the virus a low threat domestically, with only isolated outbreaks possible. Emerging treatments and potential vaccines for chikungunya remain under investigation but are not yet proven effective.
