Phylogenetic analysis of swinepox virus (A) and monkeypox virus (B) in study of co-circulating viruses, Democratic Republic of the Congo, 2022. Poxvirus sequences for comparison were obtained from GenBank. Trees were constructed by using the maximum-likelihood method and the general time reversal substitution model with gamma distribution and proportion of invariable sites. In panel A, bold text indicates the swinepox sequence from this study; in panel B, magenta-colored text indicates monkeypox virus sequences and blue text indicates swinepox virus sequence from this study. The monkeypox virus samples belong to clade I and correspond to those previously described (11). Scale bars indicate nucleotide substitutions per site. DRC, Democratic Republic of the Congo.
