Figure 1. Median-joining phylogenetic network of highly pathogenic avian influenza A(H5N8) viruse isolates identified in South Korea during 2014–2015 showing relationships with other virus isolates. The median-joining network was constructed from the hemagglutinin gene and includes all the most parsimonious trees linking the sequences. Each unique sequence is represented by a circle sized relative to its frequency in the dataset. Branch length is proportional to the number of mutations. Isolates are colored according to the origin of the sample: red inner circle, poultry farm isolates; yellow inner circle, wild bird isolates. Red asterisks indicate isolates from South Korea and blue asterisks indicate isolates from Japan identified during December 2014–February 2015.
