14 April 2014
The Centre for Health Protection (CHP) of the Department of Health (DH) today (April 14) provided an update on the 10th confirmed human case of avian influenza A(H7N9) affecting a woman aged 85.
"The epidemiological investigations, enhanced disease surveillance, port health measures and health education against avian influenza are all ongoing," a spokesman for the DH said.
As of 4pm, eight close contacts and 52 other contacts had been identified.
Close contacts are the patient's family members. One of them was symptomatic and the others have remained asymptomatic so far. Preliminary laboratory testing of all of their respiratory specimens was negative for the influenza A virus. They remain hospitalised under observation.
Other contacts include the patient's brother who travelled to Dongguan with her, relevant health-care workers (HCWs), ambulance crew members and in-patients who stayed in the same cubicle with the patient's husband in Haven of Hope Hospital, as well as staff and patients in a private clinic in Po Lam, Tseung Kwan O, which she attended. Among them, an HCW reported influenza-like symptoms and preliminary testing of her specimen was negative for the influenza A virus. The others have remained asymptomatic. All of them remain under medical surveillance.
"In view of human cases of avian influenza A(H7N9) confirmed locally and in the Mainland, further cases are expected in affected and possibly neighbouring areas. Those planning to travel outside Hong Kong should maintain good personal, environmental and food hygiene at all times," the spokesman urged.
"All boundary control points have implemented disease prevention and control measures. Thermal imaging systems are in place for body temperature checks of inbound travellers. Random temperature checks by handheld devices have also been arranged. Suspected cases will be immediately referred to public hospitals for follow-up investigation," the spokesman added.
Regarding health education for travellers, display of posters in departure and arrival halls, in-flight public announcements, environmental health inspection and provision of regular updates to the travel industry via meetings and correspondence are proceeding.
The spokesman advised travellers, especially those returning from avian influenza-affected areas and provinces with fever or respiratory symptoms, to immediately wear masks, seek medical attention and reveal their travel history to doctors. Health-care professionals should pay special attention to patients who might have had contact with poultry, birds or their droppings in affected areas and provinces.
"We have enhanced publicity and health education to reinforce health advice on the prevention of avian influenza," the spokesman said.
As of 4pm, the CHP's hotline (2125 1111) for public enquiries had received 217 calls since the first confirmed human case of avian influenza A(H7N9) in Hong Kong.
