Chikungunya virus outbreak in China has triggered alarm as over 7,000 people fall ill in Guangdong, marking the country’s biggest mosquito-borne disease crisis to date. Spread by Aedes mosquitoes, chikungunya causes fever, joint pain, and fatigue, with no specific cure yet. Chinese authorities are battling the outbreak using drones, fines, and insect control measures, while the U.S. CDC has issued travel warnings. With no vaccines available in China and rising global infections, this outbreak is a wake-up call.
