More H5N1 bird flu in US

With increased testing of wild birds in the United States, we shouldn't be surprised to find more avian influenza viruses. However, so far all of the H5N1 viruses found have been low pathogenic forms that do not pose a risk to poultry or humans and are unrelated to the virulent asian H5N1 bird flu. The latest positive results of low pathogenic H5N1 come from Green-winged Teal in Michigan.
