HANOI, Dec. 12 (Xinhua) -- Bird flu has reoccurred in Vietnam's northern Bac Giang province, raising the total number of localities currently affected by the disease to two.
Bird flu virus strain H5N1 has killed over 1,000 ducks in the two districts of Viet Yen and Yen Dung, local newspaper Saigon Liberation on Wednesday quoted a report of the country's National Anti-bird flu Steering Committee.
Bird flu virus strain H7N3, currently hitting South Korea and Canada, has not been found in Vietnam yet, said Bui Quang Anh, head of the Department of Animal Health under the Vietnamese Ministry of Agriculture and Rural Development.
Vietnam is focusing on intensifying disease surveillance, monitoring of poultry raising, transport and trade, and vaccination among fowls nationwide.
Bird flu outbreaks in Vietnam, starting in December 2003, have killed and led to the forced culling of dozens of millions of fowls in the country, according to the department.
