Introduction of Avian Influenza A(H6N5) Virus into Asia from North America by Wild Birds

Abstract

An avian influenza A(H6N5) virus with all 8 segments of North American origin was isolated from wild bird feces in South Korea. Phylogenetic analysis suggests that this virus may have been introduced into Asia by wild birds, highlighting the role of wild birds in the dispersal of these viruses.
