Epidemiology
Source of the outbreak(s) or origin of infection
  • Unknown or inconclusive
Epidemiological comments Abnormal mortalities were observed in 34 poultry farms and 1 abattoir in Miaoli County, Nantou County, Yunlin County, Chiayi County, Tainan City, Kaohsiung City and Pingtung County. Samples were sent to the National Laboratory (Animal Health Research Institute [AHRI]) for diagnosis. H5N8 subtype HPAI was confirmed by AHRI. Among 34 poultry farms, H5N2 subtype HPAI virus was also detected on 3 farms. These farms have been put under movement restrictions. All animals on the infected farms will be culled. The actual numbers of culled animals will be available when stamping out operation is finished and be reported in the next follow-up report. Thorough cleaning and disinfection will be conducted after stamping out operation. Surrounding poultry farms within 3 km radius of infected farms are under intensified surveillance for 3 months.
