Epidemiological comments |
Samples from one poultry farm in Yunlin County were sent to the National Laboratory, Animal Health Research Institute (AHRI) for analysis. Highly pathogenic avian influenza H5N2 subtype was confirmed by the AHRI. The farm has been placed under movement restriction. All animals on the infected farm have been culled. Thorough cleaning and disinfection have been conducted after stamping out operation. Surrounding poultry farms within a 3 km radius of the infected farm are under intensified surveillance for three months. Poultry carcasses were found during inspection in one illegal private abbatoir in Chiayi County. Samples were sent to the AHRI for diagnosis. H5N2 subtype HPAI was confirmed by the AHRI. The carcasses were destroyed and thorough cleaning and disinfection have been conducted in the abattoir. We have been attemping to trace back to the farm of origin. Any positive outcome will be included in the follow-up reports. Surrounding poultry farms within a 3 km radius of the infected farm are under intensified surveillance for three months. | |
