Epidemiology
Source of the outbreak(s) or origin of infection
  • Unknown or inconclusive
Epidemiological comments Abnormal mortalities were observed in seven goose farms in Chang-Hua County, Yun-Lin County, Chia-Yi County and Ping-Tung County, and one abattoir in Tao-Yuan 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 restrictions. All the geese within the infected farms will be culled. The actual number of culled geese will be available when stamping out operation will be 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.
