Bangkok: The deadly bird flu virus has killed 30 chickens in Thailand, marking the second outbreak of bird flu in 10 months, livestock officials said yesterday.
The outbreak was confirmed by tests after the poultry deaths were reported a week ago, said Pisanu Tulyawanich, head of the province's livestock department. The birds were infected with the H5 strain of bird flu and tests were under way to determine whether the bird flu was also the virulent N1 subtype. The outbreak is the second in Thailand since March 18, 2007.
Meanwhile India's worst outbreak of bird flu spread as health authorities battled to stop it reaching the densely populated city of Kolkata amid heavy rain that hampered culling efforts.
Authorities reported the disease had affected two more districts, bringing the number hit by avian flu to 12 out of West Bengal state's total of 19.
In neighbouring Bangladesh from where the Indian outbreak is believed to have spread, health teams slaughtered nearly 4,600 birds in a border area amid a worsening bird flu situation across the country.
Police and officials sealed off a one square kilometre area at Dinajpur.
