The Government will step up surveillance and watch out for any possible mutation of the avian flu virus to make sure that the vaccination programme continues to be effective, Secretary for Health, Welfare & Food Dr Yeoh Eng-kiong says.

Speaking to the media today, Dr Yeoh said a three-pronged approach - strengthened biosecurity in farms, implementation of a vaccination programme, and regular cleaning of wholesale and retail markets - has been adopted to prevent avian flu.

"These three measures have been effective so far in preventing any outbreak in Hong Kong. But obviously we are not complacent. I have asked colleagues to intensify the surveillance programmes," Dr Yeoh said.

Strategies kept under review

"In addition, I have also asked the Agriculture, Fisheries & Conservation Department colleagues to step up our surveillance on the wild birds."

It is believed that migratory wild birds are carrying the virus.

In view of the bird flu outbreaks in seven neighbouring areas, the bureau and the relevant departments reviewed at a meeting today the strategies and the surveillance systems.

Meanwhile, the Government is also monitoring any unusual deaths, both in the markets and farms, to make sure that there are no breakthrough infections from the vaccination programme.

Surveillance on wild birds reinforced

Noting that a falcon found in Tuen Mun last week was confirmed positive for H5N1, Dr Yeoh said surveillance has been reinforced.

"We are also watching out for any possible mutation of the virus to make sure that our vaccines continue to be effective," he added.

He called on the public to strictly follow good hygiene practices, and wash hands after contacting wild birds.

Bangkok meeting to share HK experience

Dr Yeoh will, at the invitation of the Thai Government, share experiences on tackling avian flu at a meeting in Bangkok on January 28.

Participating countries will also discuss ways to foster co-operation in handling avian flu outbreaks in the region.
