Evolution hypothesis of the ancestor of each gene segment for A/mallard duck/South Korea/KNU18-91/2018 (H5N3). A/aquatic bird/South Korea/sw007/2015 (a) and A/mallard duck/South Korea/KNU18-91/2018 (H5N3) (b). The reassortment event is illustrated by corresponding color segments in the descendent virus. Dashed circled represents unknown strains. Dashed squared indicates the hypothesis in which an unknown strain in China moved to South Korea and reassorted with unknown strains originated from Mongolia, generating the KNU18-91 (H5N3) strain in South Korea. HPAI, high-pathogenic avian influenza; PB, polymerase basic.
