Epidemiological comments
Samples from Changhua County, Yunlin County and Pingtung County were sent to the National Laboratory, Animal Health Research Institute (AHRI) for diagnosis. Highly pathogenic avian influenza H5N2 subtype was confirmed by AHRI. The infected farms have been placed under movement restriction. All animals on the infected farms have been culled. Thorough cleaning and disinfection have been conducted after stamping out operation. Surrounding poultry farms within 3 km radius of the infected farms are under intensified surveillance for three months. Suspected signs were observed in poultry carcasses during post-mortem inspection in two abattoirs in Taipei City and Pingtung 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. After tracing back to the farm of origin, any positive results will be included in follow-up reports.
