China is experiencing its largest outbreak of chikungunya fever, a mosquito-borne viral disease. The outbreak is concentrated primarily in Guangdong Province, especially in Foshan city, with nearly 10,000 confirmed infections reported this year. The National Disease Control and Prevention Administration has designated Guangxi Zhuang Autonomous Region in South China as a Category I risk area for chikungunya fever. Authorities have implemented aggressive containment measures, including public awareness campaigns and the release of millions of mosquitoes as part of a disease-control program. Guangdong province has recently brought the outbreak under control after several weeks, but health experts caution that vigilance must continue due to wet weather patterns in South China. The risk of importing chikungunya into Hong Kong is also expected to rise. The outbreak has prompted precautionary actions similar to those taken during the Covid-19 pandemic. Symptoms of chikungunya include fever, joint inflammation, and rash, with fatalities being rare. Additionally, artificial intelligence is being deployed as a new tool to combat mosquito-borne diseases such as dengue, which shares transmission vectors with chikungunya.
