The Hong Kong Department of Health's Centre for Health Protection said on Wednesday that a new human case of avian influenza was reported in Anhui and it is closely monitoring the patient.
The patient is a 69-year-old man who is in the hospital receiving treatment.
"Locally, enhanced disease surveillance, port health measures and health education against avian influenza are ongoing," a spokesman for the Department of Health said. "We will remain vigilant and maintain liaison with the World Health Organization and relevant health authorities. Local surveillance activities will be modified upon the WHO's recommendations."
The spokesman said more cases of avian influenza are expected in affected and neighboring areas.
"Those planning to travel outside Hong Kong should maintain good personal, environmental and food hygiene at all times," the spokesman said.
Authorities on the Mainland have confirmed a total of 402 human cases of avian influenza A.
Boundary control points have been set up to assist in controlling the illness. The points use thermal imaging and random temperature checks to monitor body temperature of inbound travelers.
The CHP encouraged travelers to wear respiratory masks and seek medical attention as soon as symptoms arise.
Members of the public were encouraged to avoid live poultry markets, contact with live birds and their droppings. All meat and eggs should be thoroughly cooked before consumption.
