A 45-year-old man in Tsing Yi is the third confirmed local case, prompting expanded surveillance-and-mosquito-control efforts
Hong Kong health authorities have reported the third locally acquired case of Chikungunya fever in the city, a 45-year-old man residing in the Mount Haven estate in Tsing Yi and working in Sheung Wan.
He developed fever, joint pain and rash on October 30 and sought treatment at a hospital, where his infection was confirmed in a mosquito-free ward.
The patient has no travel history in the preceding three months and did not visit Fung Tak Estate in Wong Tai Sin, the site of previous local cases, raising concern of a second source of transmission.
The Centre for Health Protection (CHP) has begun genome sequencing to assess whether the latest infection links to earlier local cases or represents a new transmission chain.
Around 1,500 households in the nearby estate area will undergo health surveys and screening, while city-wide mosquito suppression efforts remain reinforced.
An 82-year-old woman from Wong Tai Sin, identified on October 26, and a 55-year-old woman from the same district, confirmed on October 31, represent the first two local-acquired infections in Hong Kong.
To date in 2025, Hong Kong has recorded 55 confirmed chikungunya cases, including three local and the remainder imported.
The city’s health and environmental agencies continue to emphasise mosquito-breeding site elimination, use of insect repellent and early clinical detection, especially as neighbouring Guangdong Province endures a large outbreak numbering thousands of cases.
Officials noted that while the risk of widespread transmission remains “not high” thanks to rapid intervention, the unforeseen third case underscores the need for vigilance.
Residents with symptoms such as sudden fever, joint pain and rash — particularly if they live in or have visited affected districts — are urged to seek immediate medical attention.
The CHP will maintain enhanced surveillance and vector control until local spread is confidently ruled out.
