Figure 2. Phylogenetic tree of isolates from outbreak of vaccinia virus from occupational exposure, China, 2017, compared with reference isolates. The tree was constructed by using nucleotide sequences of Orthopoxvirus A56R hemagglutinin genes and the maximum-likelihood method with 1,000 bootstrap replicates in MEGA5 (https://www.megasoftware.net). Black dots indicate isolates from this study. Numbers along branches indicate bootstrap values. Scale bar indicates nucleotide substitutions per site. CPXV, cowpox virus; MPXV, monkeypox virus; VACV, vaccinia virus; VARV, variola virus.
