Abstract

Highly pathogenic avian influenza A(H5N8) clade 2.3.4.4 virus emerged in 2016 and spread to Russia, Europe, and Africa. Our analysis of viruses from domestic ducks at Tanguar haor, Bangladesh, showed genetic similarities with other viruses from wild birds in central Asia, suggesting their potential role in the genesis of A(H5N8).

Keywords: Bangladesh; Egypt; United States; central Asian flyway; clade 2.3.4.4; highly pathogenic avian influenza A(H5N8); influenza; respiratory infections; viruses; zoonoses.
