Figure 2.

Maximum-likelihood (ML) phylogenetic tree of VSBV-1 based on complete coding sequences showing the phylogenetic placement of the human-derived strains compared with squirrel-derived strains. Sequence information is coloured to illustrate different hosts. Spill-over infections to humans are shown in red. Human cases B and C are not included, as no complete virus genomes were available. Virus infections in zoos are shown in shaded areas. ML bootstrap replicates scores (>70%) are shown next to the nodes. Taxon information includes GenBank accession number, sample designation, host, year of detection and location. Scale bar indicates nucleotide substitutions per site.
