More Vietnamese poultry farms affected by H5N1
Two provinces in Vietnam have reported outbreaks of H5N1 avian flu in poultry, an article from Xinhua, China's news agency, reported today. One of the outbreaks follows one in the same province late last month, raising alarm over the infection's spread to other areas and to humans.
On a farm in the Tinh Gia district of Thanh Hoa, a central province, 186 chickens testing positive for H5N1 died Feb 8, says the story. That farm as well as neighboring ones was asked by the Department of Agriculture and Rural Development to cull and safely dispose of all their chickens to contain the outbreak.
The other outbreak occurred in the central highlands province of Kon Tum, where 600 chickens displayed symptoms of H5N1 and 470 died Feb 8. The story says the remaining 130 chickens on the farm were culled after "the official conclusion was reached" that they had H5N1. VNA, Vietnam's state-run news agency, reported an outbreak Jan 28 in Kon Tum that involved 1,000 ill or dead chickens, the Xinhua story says.
In a related development, a veterinarian who had contact with the birds in the Kon Tum outbreak is reportedly hospitalized and isolated with suspected H5N1 avian flu, says Xinhua. Vietnam has among the most human H5N1 cases in the world.
