Highly pathogenic avian influenza a(H5N8) viruses reintroduced into south korea by migratory waterfowl, 2014-2015

Abstract

Highly pathogenic avian influenza A(H5N8) viruses were isolated from migratory waterfowl in South Korea during fall 2014-winter 2015, a recurrence after initial introduction in winter 2014. These reappeared viruses were phylogenetically distinct from isolates circulating in poultry farms in South Korea.
