老挝北部发现了禽流感疫情
Authorities in Laos detected a fresh outbreak of bird flu in the north of the country last week and slaughtered all poultry affected, a government spokesman says.
The government did not say how many birds were infected with the deadly virus, which was detected in a village about 150km north of the ancient royal capital Luang Prabang, a UNESCO World Heritage site.
"We have killed all of the poultry within a kilometre radius - about 7,000 of them," and a quarantine zone has been set up on the area's perimeter, foreign ministry spokesman Yong Chanthalangsy told AFP.
No human infections were suspected, he said.
Two people have died of bird flu in communist-ruled Laos since 2003, when the virus resurfaced in Southeast Asia, according to World Health Organisation (WHO) statistics. Both deaths were reported last year.
The WHO says 243 people have died from bird flu worldwide. The H5N1 avian influenza virus mainly kills birds but scientists fear it could mutate to easily jump from human to human, sparking a global pandemic.
