Epidemiology
Source of the outbreak(s) or origin of infection
  • Unknown or inconclusive
Epidemiological comments Abnormal mortalities were observed in 9 poultry farms in Yunlin County, Pingtung County and Kaohsiung City. Two dead wild birds (Passeridae) were found in Changhua County. Samples were sent to the National Laboratory (AHRI) for diagnosis. H5N2 subtype HPAI was confirmed by AHRI. These farms have been put 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 3 months.
