    Abstract

    We detected Eurasian-origin highly pathogenic avian influenza A(H5N1) virus belonging to the Gs/GD lineage, clade 2.3.4.4b, in wild waterfowl in 2 Atlantic coastal states in the United States. Bird banding data showed widespread movement of waterfowl within the Atlantic Flyway and between neighboring flyways and northern breeding grounds.

    Keywords: United States; clade 2.3.4.4; dispersal; highly pathogenic avian influenza A(H5N1) virus; influenza; influenza viruses; intercontinental movement; respiratory infections; viruses; wild birds; zoonoses.
