No additional cases of a new strain of avian influenza (H5N1) have been discovered in the DPRK, according to the first follow-up report submitted [PDF] to the World Organisation for Animal Health [OIE] on 22 May 2013 by Ri Kyong Gun, Director of the Veterinary Anti-Epizootic Department of the DPRK Ministry of Agriculture. According to the DPRK’s reporting to OIE, the birds in cages infected with the avian flu strain were “humanely culled” and that an “inactivated monovalent vaccine” was being administered on approximately 500,000 livestock and animals in the DPRK’s 12 provinces. On 19 April 2013, DPRK agricultural workers discovered an avian flu outbreak in a cage of ducks at the Tudan Duck Farm in east Pyongyang. Additional testing of duck cages from the Tudan Farm were tested by laboratories of the Ministry of Agriculture and State Academy of Science, which showed that 20 additional duck and duckling cages at Tudan Farm tested positive for avian flu. The DPRK has not been to determine the original source of the infection, however in its follow-up report to the OIE it said it had taken a number of precautions including screening other animals for symptoms, disinfecting farms where the virus has been found, restricting and/or prohibiting the transport of animals within the country, quarantining and administering vaccinations.
