Maximum clade credibility tree constructed using the hemagglutinin gene of highly pathogenic avian influenza A(H5N1) clade 2.3.4.4b virus, with geographic region as a discrete trait, South Korea, June 2022–January 2023. Each branch is colored according to the geographic region specified in the legend. Each genotype was assigned an alphabet letter based on the Kor22–23 nomenclature, which indicated the region of origin (Kor) and year of origin (2022–2023). Orange shade represents Kor22–23B genotype viruses. Violet shades represent Kor22–23C genotype viruses. Blue shades represent Kor22–23D genotype viruses. The x-axis is in decimal year format.
