CHP announces one new melioidosis case
The Centre for Health Protection (CHP) of the Department of Health today (January 16) announced that one new melioidosis case was recorded in the past week (January 9 to 15). The CHP appealed to members of the public to maintain personal and environmental hygiene to prevent melioidosis. The CHP also specifically reminded high-risk groups, including the elderly and people with underlying diseases, to avoid contact with soil or muddy water after typhoons or storms with a view to lowering infection risk.
The case involves a 58-year-old male with underlying illnesses living in Kwai Tsing District. He presented with a fever and vomiting since January 10, followed by confusion on the next day (January 11). He was then sent to the Accident and Emergency Department of Yan Chai Hospital and is currently in the intensive care unit in critical condition. The clinical diagnosis was pneumonia. His clinical sample was confirmed to be positive for Burkholderia pseudomallei upon testing.
The CHP is investigating the infection source of the case. Initial epidemiological investigations revealed that the case is sporadic. No epidemiological linkages have been established between this case and other confirmed cases previously recorded in Hong Kong.
As of yesterday (January 15), one melioidosis case has been recorded in Hong Kong this year. In 2025, 21 melioidosis cases were recorded.
Person-to-person transmission and animal-to-human transmission are rare, but the bacteria causing melioidosis can survive in the local environment. Melioidosis is an endemic disease in Hong Kong, and melioidosis cases have been recorded in Hong Kong each year.
According to literature, melioidosis cases are more common after typhoons or rainstorms. The bacterium Burkholderia pseudomallei in soil and muddy water may become exposed to the ground after typhoons or rainstorms, and the bacteria could spread more easily with strong winds or rainstorms. As such, the number of melioidosis cases may increase.
With this in mind, where practicable, members of the public should stay indoors during typhoons and rainstorms, avoid travelling to areas with potential flooding, and not wade in or have contact with muddy water and soil. In addition, high-risk individuals should avoid paths near stormwater drains where aerosols may be generated from contaminated water.
Members of the public should also take the following preventive measures against infection:
The CHP appealed to members of the public to seek medical advice if they develop symptoms, in particular people with diabetes or other immunocompromising conditions, in order to receive an appropriate medical diagnosis and treatment.
