Hepatitis C Virus Genotypes in Blood Donors and Patients with Chronic Hepatitis C

The hepatitis C virus genotype and subtype frequency in hepatitis C virus RNA‐positive, hepatitis C virus antibody‐negative blood donors identified in the nucleic acid test screening program in Poland

“…Control groups in our study (seropositive blood donors and CHC patients) were diagnosed within the same period of time as the wp donors. The genotype distribution in both control groups, however, was similar to those observed in our previous study 15‐17 conducted between 1995 and 1999, where the Subtype 1b frequency among seropositive blood donors was 78.6 percent, and among adult CHC patients, 72.5 percent. Subtype 3a was detected in 10 percent of blood donors and in 14.6 percent of CHC patients, whereas Genotype 4 was found in 1.4 and 1.7 percent, respectively.…”
