Phylogenetic analysis of the hemagglutinin gene of highly pathogenic avian influenza A(H5N1) clade 2.3.4.4b viruses isolated from domestic ducks during outbreaks in South Kalimantan, Indonesia, in April 2022 and July 2023 compared with reference sequences. Bold font indicates the viruses isolated from duck farms in this study. Letters at right indicate subclades. Evolutionary history was inferred by using the maximum-likelihood method and best-fit general time reversible plus gamma distribution 4 substitution model involving 67 hemagglutinin H5 sequences from the GISAID database (http://www.gisaid.org); a total of 1,656 positions were in the final dataset. Scale bar indicates nucleotide substitutions per site.
