k-step network of the AW outbreak. Each node is a distinct HCV variant (n = 6231) found among the 18 samples. The size of the node is proportional to the number of samples that share that variant. Red nodes are variants found in the source; yellow nodes are variants found exclusively among recipients. Out of 11,418 links, 94.35% have a Hamming distance of 1, 5.24% a distance of 2, 0.32% a distance of 3, 0.06% a distance of 4, and 0.03% a distance of 15
