Phylogenetic tree analysis of NS5B and HVR1 region of HCV. The analysis of NS5B was performed for 10 incident cases and the index case (all genotype 2c). The analysis of HVR1 was possible for 8 incident cases only. Molecular analysis was not performed for 3 incident cases due to low viral load (< 615 UI/ml). Blue boxes include the viral variants from subjects in the current outbreak; each code refers to only one subject. Code 00 indicates the index case. Code 02, 04, 07, 09, 10, and 13 are confirmed cases dialysed on 20 April afternoon shift. Code 01 and 05 are confirmed cased who did not undergo dialysis on 20 April. Code 11 and 12 are possible cases (analysis of HVR-1 not available) dialysed on 20 April afternoon shift. Gray boxes include viral variant from other unrelated outbreaks.
