From: Surveillance of avian influenza viruses from 2014 to 2018 in South Korea

Phylogenetic analyses of the three most prevalent hemagglutinin subtypes collected in South Korea during winter from November 2014 to January 2018. Assembled full and partial (a) H1, (b) H5, and (c) H6 sequences of isolates (blue, bold-italic) compared with full coding sequences available at GenBank and GISAID. Isolates in bold red (b, H5 tree) indicate highly pathogenic avian influenza viruses (HPAI). Isolates collected from the Americas are labeled in magenta. Circles at nodes indicate transfer support values from 60 to 100%; the size of the circle is proportional to the bootstrap score. AB aquatic bird, Ck chicken, Dk duck, Gs goose, Md mallard, Kor Korea.
