Epidemiological comments

During the first round surveillance conducted on the poultry farms around the H5N2 infected duck farm detected in Hua-Lien County, the H5N3 avian influenza virus was isolated from swabs taken from a meat-type duck farm on 16 July 2013. Movement restriction was conducted on this infected farm. The result of clinical investigation showed that the duck were in healthy condition without clinical signs and abnormal mortality. Subsequently, the national laboratory confirmed this H5N3 case as LPAI by virological tests and pathogenicity test on 2 August 2013. The surveillance of poultry farms around the H5N3 affected farm are in progress.

Note by the OIE Animal Health Information Department: H5 and H7 avian influenza in its low pathogenic form in poultry is a notifiable disease as per Chapter 10.4. on avian influenza of the Terrestrial Animal Health Code (2012).
