H5N1 Avian influenza found on poultry farm in Laos

28 July, 2006

An outbreak of the H5N1 strain of avian influenza has killed more than 2,000 chicken on a poultry farm in Laos, the government and UN Food and Agriculture Organization (FAO) said.
Veterinarians had slaughtered 6,000 more birds on the farm about 25 kilometres (15 miles) south of the national capital, disinfected the cages and declared a five-kilometre (three-mile) surveillance zone, they said.
The Xaythani district farm, which previously suffered a avian influenza outbreak in early 2004, found 155 dead chickens on July 14, and about 2,000 dead birds the following day, said the FAO chief technical advisor on avian influenza in Laos, Ricarda Mondry.
In May this year, Laos found the H5N1 virus in a single duck in a backyard farm near the capital Vientiane, but extensive testing in villages in following months had found no further cases.
Laos has so far reported no human deaths from the virus, which has swept across Asia and beyond in several waves since 2003, but neighbouring Thailand this week reported its 15th human fatality.
