    Animal health officials in Dien Chau District said Wednesday that the 12-day-old ducklings and eight chickens at a livestock farm owned by Cao Xuan Hao have been killed after they were found infected with the H5N6 virus, also known as bird flu.

    On July 28, nearly 90 ducklings at Hao?s farm died suddenly and district animal health officials collected tissue samples from the birds. Test results found the birds had contracted the H5N6 virus.

    Last month, the northern province of Hai Phong, around 400 kilometers to northwest of Nghe An, also reported two bird flu outbreaks and more than 10,000 infected birds were killed, VTV reported.
