    Vietnam culls 30,000 poultry to stem bird flu outbreak

    Vietnamese medical staff vaccinate chickens against bird flu virus. Photo by Voice of Vietnam. About 30,000 poultry have been slaughtered across Hanoi and north-central Thanh Hoa Province following bird flu infection.


    Over 23,000 ducks and chickens in Thanh Hoa and about 6,800 ducks in Hanoi had been infected with the influenza A virus subtype H5N6 (A/H5N6), said Nguyen Ngoc Son, head of Hanoi’s Veterinary Department on Monday.

    The outbreak was discovered about a week ago among a flock of ducks raised by Nguyen Ngoc Son in Hanoi’s Chuong My District, from where it spread to the flocks of three other families in the area.

    Chuong My authorities have since destroyed the ducks, halted the transportation of poultry in and out of the area, and disinfected and vaccinated all poultry in the district, said Son. Those who noticed symptoms such as swelling or lack of appetite among the poultry they raise must report to authorities promptly, he added.

    In Thanh Hoa, the infected poultry belonged to 10 families in Nong Cong and Quang Xuong Districts./...https://e.vnexpress.net/news/news/vi...k-4053456.html
