Figure 1 Human PIV3 outbreak at a stem cell transplant (SCT) center and relationship to community-wide prevalence. Biology of Blood and Marrow Transplantation 2004 10, 58-64DOI: (10.1016/j.bbmt.2003.09.010)

Figure 2 Estimated maximum parsimony tree obtained from alignment of partial hPIV3 hemagglutinin-neuraminidase gene sequences (778 nt) from 46 cases and 8 community control patients. Genetic distances between sequences are shown as the number of differing nucleotides; bootstrap values for 100 iterations are indicated for selected nodes.
