Epidemiological comments Abnormal mortality was noticed and reported to the local disease control center by the owner of the breeding goose farm. Two dead geese were taken from the farm for diagnosis and the farm has been put under movement restrictions since then. Specific RNA product of avian influenza virus was detected and subtyped as H5N8 by RT-PCR. Highly pathogenic avian influenza was confirmed by the National Laboratory based on sequencing analysis of HA0 cleavage site. All the geese on the infected farm will be culled. The actual number of culled geese will be available when stamping out will finish and be reported in the next follow-up report. Thorough cleaning and disinfection will be conducted after stamping out operation. Surrounding poultry farms within a 3 km radius of the infected farm are under intensified surveillance for 3 months.

(Reuters) - Taiwan has reported an outbreak of the highly pathogenic H5N8 bird flu virus on a goose farm, the World Organisation for Animal Health (OIE) said on Tuesday.

The outbreak started on Jan. 8 at a farm in Da-Lin Township, Chiayi County and killed 3,683 out of 5,200 birds, the Taiwanese authorities said in a report to the Paris-based OIE.

The strain is the same as in other cases found in Europe, North America and elsewhere in Asia in the past year.
