Figure 5. Discrete phylogeographic reconstruction of diffusion dynamics of influenza A(H5N6) viruses in East Asia during 2022–2023 used in a study of transmission dynamics of highly pathogenic avian influenza A(H5N1) and A(H5N6) viruses in wild birds, South Korea, 2023–2024. A) Maximum clade credibility tree constructed using the hemagglutinin gene of H5N6 viruses. Each branch is colored according to the geographic location. Scale bar shows years of detection in decimal year format. B) Visualization of transmission dynamics inferred by using the geographic location traits within South Korea. Arrows represent the direction of the viral transmission; annotated values represent Bayes factors. Thick arrow indicates a strongly supported route (Bayes factor >20, posterior probability >0.8).
