The Government has gazetted earlier to include melioidosis as a statutory notifiable infectious disease under Schedule 1 of the Prevention and Control of Disease Ordinance (Cap. 599).
The CHP will continue to work closely with the Hospital Authority to step up surveillance of melioid cases.
A spokesman for the Center for Health Protection said that melioidosis generally does not spread from person to person or through animals, but melioidosis can survive in the local environment.
Melioidosis is an endemic disease in Hong Kong, and human cases of melioidosis have been recorded every year in Hong Kong.
According to the literature, infection cases appear more often after typhoons or heavy rains.
After a typhoon or heavy rain, Burkholderia pseudomallei in soil and muddy water may be exposed to the ground, and with strong winds or heavy rains, the melioidosis bacteria are more likely to spread, which may increase the number of melioidosis cases.
