Epidemiological comments

As part of the continuous avian influenza surveillance programme, Jeollanam-do Institute of Livestock and Veterinary Science tested samples (f?ces and laryngo-pharyngeal swabs) collected from a duck farm in Sukma-ri on 27 October. Haemagglutination test results were positive on 1 November. National Veterinary Research and Quarantine Service (NVRQS) found avian influenza antigen (H7) by PCR on 3 November and confirmed it as low pathogenic avian influenza virus (H7N6) by gene sequencing on 4 November.
As a precautionary measure, all poultry in the affected farm were culled on 3 November.

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 (2010).
