Hong Kong detects first local chikungunya case of 2026; doctors urged to test

Hong Kong's Centre for Health Protection confirmed the city's first locally acquired chikungunya fever case of 2026 in a 55-year-old woman with no travel history, prompting a directive for doctors to test symptomatic patients regardless of travel history. The case signals potential local transmission of the mosquito-borne virus, which is unusual for Hong Kong and raises public health concerns. The extent of local spread remains uncertain pending further surveillance.
