      • As part of the yearly surveillance programme, a member of the Livestock Health Control Association collected samples from a duck raising farm in Seo-san city and requested the test for avian influenza to the Chungchong-namdo Veterinary Research Institute (VRI) on 7 December 2009.
      • After it was positive by haemagglutination test, the sample was sent to the National Veterinary Research and Quarantine Service (NVRQS) on 22 December. In the course of the confirmatory test, the isolated virus was confirmed as H5 avian influenza virus on 24 December and finally confirmed as low pathogenic avian influenza virus (H5N2) by gene sequencing.
      • 26,800 ducks raised in the affected farm were culled and 176,000 eggs kept in the farm were destroyed. The whole procedure for burial and burning was completed on 26 December. Traceback investigation of epidemiologically related farms and enhanced surveillance on neighbouring farms are underway.
