Abstract
We report the identification of novel highly pathogenic avian influenza viruses of subtype H5N6, clade 2.3.4.4, that presumably originated from China. In addition, reassortant strains with Eurasian lineage low pathogenic avian influenza viruses were isolated in wild birds and poultry in South Korea. The emergence of these novel H5N6 viruses and their circulation among bird populations are of great concern because of the potential for virus dissemination with intercontinental wild bird migration.
