Characterization of Low-Pathogenicity H5N1 Avian Influenza Viruses from North America
30 Aug 2007

Wild-bird surveillance in North America for avian influenza (AI) viruses with a goal of early identification of the Asian H5N1 highly pathogenic AI virus has identified at least six low-pathogenicity H5N1 AI viruses between 2004 and 2006.
