South Korea reports eight bird flu outbreaks on farms

South Korea has reported eight cases of H5N6 bird flu on farms, prompting the culling of more than 500,000 poultry, the World Organisation for Animal Health says.

The outbreaks of highly pathogenic avian influenza, commonly called bird flu, were detected between December 5 and December 11, in villages in the western part of the country, the WOAH said in a report posted on its website citing information from South Korean authorities.

The virus killed a total of 47 birds while another 513,810 were culled, the Paris-based WOAH said.

Earlier this month South Korea reported an outbreak of the H5N1 strain which has been spreading around the globe, including in Japan and Cambodia in Asia, but it had not reported any outbreaks of H5N6.

The H5N6 strain over the past four years has only been detected in Asia, the WOAH database showed, with the latest outbreak on a poultry farm in the Philippines in January.

The strain has infected a large number of people in China in the past years, raising concern among some experts.

Between 2014 and December 16 of this year, there were 88 human cases of avian influenza A(H5N6) reported globally with 87 of those occurring in mainland China, Hong Kong's Centre for Health Protection (CHP) said in a report released on Tuesday.

The latest human case was reported on September 27, it said.
