Assessment Of Introduction Pathway For Novel Avian Influenza Virus Into North America By Wild Birds From Eurasia, Ryan S. Miller, Steven J. Sweeney, Judy E. Akkina, Emi K. Saito

Zoonotics and Wildlife Disease: Publications

A critical question surrounding emergence of novel strains of avian influenza viruses (AIV) is the ability for wild migratory birds to translocate a complete (unreassorted whole genome) AIV intercontinentally. Virus translocation via migratory birds is suspected in outbreaks of highly pathogenic strain A(H5N1) in Asia, Africa, and Europe. As a result, the potential intercontinental translocation of newly emerging AIV (e.g. A(H7N9) from Eurasia to North America via migratory movements of birds) remains a concern. An estimated 1.48 to 2.91 million aquatic birds, principally Anseriformes (ducks, geese, and swans) and Charadriiformes (gulls, terns, and shorebirds) move annually between Eurasia and North …
