Epidemiological comments Samples from Yunlin County were sent to the National Laboratory, Animal Health Research Institute (AHRI) for diagnosis. Highly pathogenic avian influenza H5N5 subtype was confirmed by AHRI. The infected farm in Yunlin County 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. The infected farm in Yunlin County was cleaned and disinfected. Surrounding poultry farms within 3 km radius of the infected farm and the sampling spot are under intensified surveillance for three months. Suspected signs were observed in poultry carcasses during post-mortem inspection in the abattoir in Taipei City. Samples were sent to the AHRI for diagnosis. H5N5 subtype HPAI was confirmed by the AHRI. The carcasses were destroyed and thorough cleaning and disinfection have been conducted in the abattoir. After tracing back to the farm of origin, any positive results will be included in follow-up reports.
