The highly pathogenic (HPAI) H5N1 strain of avian influenza has not been detected in the United States or anywhere in North America. Low pathogenic (low probability of creating disease) strains of avian influenza, however, are commonly present in...
Avian influenza viruses are common in North American waterfowl and shorebirds, but most strains found in wild birds are not highly pathogenic (able to produce disease) and do not lead to severe illness in the infected birds.The highly pathogenic form of...
