Phylogenetic tree of HDV sequences (575 bp, positions 500–1055 to the reference HDV X04451.1) from participants in this study with the most similar HDV sequences from the literature (> 93% of identity). Sequences were annotated with the country and the year in which the study was conducted. HDV sequences derived from Vietnamese people were highlighted in blue, and those from this study were highlighted in red.
