Figure 1From: Molecular evolution in court: analysis of a large hepatitis C virus outbreak from an evolving sourceDistribution of differences in the NS5B region. Sequences were compared with a 229-nucleotide (nt) fragment of the NS5B gene derived from the presumed source (PS). The graph shows the distribution of nucleotide differences (Hamming’s distance) for sequences derived from patients included in the outbreak (red bars), from patients excluded (dark purple) from the outbreak, and from local controls (grey). The inset shows the same distribution for putative outbreak samples (dark blue) and local controls (gray) before the former were divided into included and excluded from the outbreak.Back to article page
