- We isolated a novel H5N2 avian influenza virus from swans in China. The virus was derived from a widespread H9N2 avian influenza virus but acquired the hemagglutinin gene from Eurasian H5 subtype with a naturally occurring in-frame deletion of four basic residues in the polybasic hemagglutinin cleavage site.
