Source of the outbreak(s) or origin of infection
  • Unknown or inconclusive
Epidemiological comments Samples from 9 poultry farms in Nantou County, Yunlin County, Chiayi County, Changhua County and Tainan City 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 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 a 3 km radius of the infected farms are under intensified surveillance for 3 months. Suspected signs were observed in poultry carcasses during post-mortem inspection in 1 abattoir in New Taipei City. 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.
