Epidemiological comments |
Samples from Chiayi County and Taoyuan City were sent to the National Laboratory, Animal Health Research Institute (AHRI) for diagnosis. H5N2 subtype avian influenza was confirmed by AHRI. The infected farms were placed under movement restrictions. The pathogenicity of the virus was subsequently confirmed by the AHRI as low pathogenic (less than 75% mortality of the tested chickens) on 17 December 2019. Surrounding poultry farms within 3 km radius of the infected farms were placed under intensified surveillance for three months. | |
