          Epidemiology
          Source of the outbreak(s) or origin of infection
          • Unknown or inconclusive
          Epidemiological comments Samples from Yunlin County and Changhua 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.
