Highly pathogenic avian influenza A(H5N6) virus Clade 2.3.4.4h in wild birds and live poultry markets, Bangladesh

Migratory birds play a major role in spreading infl uenza viruses over long distances. We report highly pathogenic avian infl uenza A(H5N6) viruses in migratory and resident ducks in Bangladesh. The viruses were genetically similar to viruses detected in wild birds in China and Mongolia, suggesting migration-associated dissemination of these zoonotic pathogens.
