Figure 2. Phylogenetic tree depicting the relationship of the monkeypox virus strain detected in a genital lesion sample from a patient in Sweden to previously published isolates and the strain repsonsible for the 2022 multinational outbreak. The x-axis represents the branch lengths, interpreted as the number of nucleotide substitutions per site. The y-axis represents the tree cardinality (e.g. the amount of sequences represented in the tree) of each clade.
