Vietnam reported outbreaks of avian flu H5N1 and H5N6 in northern Cao Bang province, the National Institute of Hygiene and Epidemiology (NIHE) said on Monday.
Accordingly, in 34 households in Quoc Toan community, Cao Bang’s Tra Linh district and one household in Cao Bang City’s Song Bang ward, massive deaths of chicken with unknown reason were recorded, the local Tien Phong (Pioneer) newspaper reported.
Local animal health officials took samples and sent them to the NIHE for test. The test results showed that dead poultries in Tra Linh district were positive with avian influenza H5N1 while those in Cao Bang City were positive with H5N6 strain.
Cao Bang’s authorities have culled a total of 4,015 chicken and 18 doves as well as sterilized poultry cages and surrounding environment in two virus-hit areas.
The province has over 330 km of shared border with China, where avian influenza H7N9 virus is detected.
