Two ducks in Vietnam's capital, Hanoi city, have been infected with bird flu virus, local newspaper Labor reported yesterday.

Specimens from the ducks in a market in Thanh Tri district have been tested to positive to bird flu virus strain H5, the paper quoted sources from the country's Central Veterinary Center as saying.

Recently, Vietnam has also detected some waterfowls in the three southern provinces of Ben Tre, Long An and Tien Giang contracting bird flu viruses, including the strain H5.

Vietnam will form anti-bird flu task forces at both central and local levels to stamp out any disease outbreaks timely and comprehensively.

Bird flu outbreaks, starting in Vietnam in December 2003, have killed and led to the forced culling of dozens of millions of fowls. The last outbreak of bird flu among poultry in the country was in December 2005, according to the Department of Animal Health under the Vietnamese Ministry of Agriculture and Rural Development.
