Neighbor-joining tree obtained with the NS5B-region sequences of hepatitis C virus (HCV)-1a samples analyzed in this study. Color codes: outbreak sequences are in black, red, and green (see legend to Figure 3), excluded from the outbreak are in dark purple, and local unrelated controls are in gray. The presumed source (PS) sequence is shown in blue. No clade was found with bootstrap support higher than 70%.
