Some media are reporting that the Asian H5N1 strain of highly pathogenic avian influenza has now entered the United States. This is incorrect. The avian flu that was recently found in a green-winged teal in Washington state is a different strain and is not known to harm humans nor has it been found in domestic poultry. This Washington state strain incorporates genes from North American waterfowl-associated viruses. Unlike the Asian H5N1 strain that has been found in Asia, Europe, and Africa, this Washington state strain has only been found in wild waterfowl and has not been associated with human illness, nor has this new Washington state strain been found in domestic poultry. §

Good to know. It also seems eerily over-specific. I have to wonder exactly how a green-winged teal came to be tested for the flu. Did it show up at the drugstore doc-in-a-box with a fever?
