HANOI, Jan. 9 (Xinhua) -- Vietnam's northern Quang Ninh province has recently detected three outbreaks of H5N6 bird flu outbreaks which have affected thousands of fowls, the provincial animal health bureau said on Wednesday.
The latest outbreak, spotted on Monday, infected 3,000 chickens raised by a household in Hai Ha district. All the affected chickens have been culled to prevent the disease from spreading.
Earlier, one H5N6 outbreak was detected in Quang Ninh's Mong Cai city and another in Tien Yen district. Before being infected with H5N6 virus strain, the poultry had not been vaccinated against bird flu viruses, said the bureau.
On Monday, the Department of Agriculture and Rural Development of Vietnam's southern Long An province announced that one H5N1 bird flu outbreak has recently stricken the province, killing and leading to the forced culling of thousands of chickens and ducks.
Vietnam has detected no new human cases of H5N1 infection since 2014, according to the country's Ministry of Agriculture and Rural Development.
