China intensifies fight against chikungunya amid outbreak concerns

China's Guangdong province is battling its largest chikungunya outbreak in history, with over 8,000 cases, prompting aggressive mosquito control measures. The virus, transmitted by Aedes mosquitoes, causes symptoms like fever and joint pain, and can lead to chronic illness. Despite the severity of the response, experts note that some measures may be excessive given the virus's low fatality rate and limited airborne spread, but the outbreak's scale and China's lack of population immunity justify strict actions. The situation remains under close watch as the disease could spread further.
