1st February 2026 – (Hong Kong) Hong Kong health authorities have confirmed two new imported cases of chikungunya fever, both linked to recent travel to the Seychelles. The Centre for Health Protection said laboratory tests detected chikungunya virus in a 55‑year‑old woman from Kowloon City District and a 55‑year‑old man from the Central and Western District. Officials consider both infections imported, noting each patient visited the Seychelles during the incubation period and that the cases are not epidemiologically linked.

The woman travelled to the Seychelles from 19 to 25 January, developed joint pain on 27 January and a rash the next day. She sought care at the Prince of Wales Hospital’s accident and emergency department on 30 January and was admitted to a mosquito‑free ward; her condition is stable. The man returned from a solo trip to the Seychelles between 25 and 28 January and experienced fever, joint pain and a rash on 30 January. He attended a private hospital on 31 January and was subsequently admitted to Queen Mary Hospital, also in a mosquito‑free environment, where he remains stable.

Each patient has one household contact. One of the contacts also travelled to the Seychelles. All contacts are currently symptom‑free and under medical surveillance. The CHP will notify the relevant health authority regarding the imported cases.

So far this year, Hong Kong has logged two confirmed cases of chikungunya fever, both imported. In 2025, the city recorded 82 confirmed cases, including 11 local infections. Preventive work continues following last year’s local cases associated with visits to the Tsing Yi Nature Trails, which remain closed while multiple departments carry out ongoing mosquito control and environmental remediation. Citywide vector control has been stepped up since July, with targeted fogging, routine removal of stagnant water, weekly inspections and enhanced public education, and further intensification of measures planned.
