Epidemiology
Source of the outbreak(s) or origin of infection
  • Unknown or inconclusive
Epidemiological comments The low pathogenic viral infection was detected on a meat-type duck farm in the process of active surveillance and identified as H5N2 strain by virus isolation. Movement restriction and investigation were implemented on the infected farm. The ducks within the farm were normal without clinical signs. Subsequently, the national laboratory confirmed this H5N2 outbreak as LPAI by virological tests and pathogenicity test on 2 August 2013. The surveillance of poultry farms around the H5N2 affected farm is 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).
