Epidemiology
Source of the outbreak(s) or origin of infection
  • Unknown or inconclusive
Epidemiological comments Samples from Taipei City and Yunlin 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 in Yunlin County 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. The samples collected from Taipei City were discarded dead chicken found in the Guandu Natural Park. The sampling spot was disinfected. Surrounding poultry farms within 3 km radius of the infected farms and the sampling spot are under intensified surveillance for three months. Suspected signs were observed in poultry carcasses during post-mortem inspection in one abattoir in 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.
