Abstract
This study was performed to determine the prevalence of HBV and HCV infection among blood donors and the occurrence of HEV in hepatitis viruses seropositive blood donors. Also, to investigate the correlation between the occurrence of hepatitis viruses and other risk factors (gender, age, occupation, educational level, residency and donors' types). A total of 11,604 blood samples fromapparently healthy blood donors of age range 18-60years old were collected. The blood donors were categorized as voluntary and replacement donors. Blood samples from donors were tested for the presence of HBsAg, HCV and HEV antibodies by using Enzyme-linked immunosorbent assay. The overall results indicated that 671 out of 11,604 blood donors; 370 persons (3.188%) HCV, 295 persons (2.542%) HBV and 6 persons (0.052%) HCV and HBV; were hepatitis viruses seropositive donors. The prevalence of HEV were 193 (28.76%) among these seropositive blood donors. There is a highly significant correlation among HCV, HBV and other risk factors. Also, the HEV showed high significant with age and educational level and significant with donor types and locations. All investigated virus combinations (HEV/HCV, HEV/HBV and HEV/HCV/HBV) were highly significant with the risk factors except for occupation. In conclusion, the HEV is significantly correlated to HCV and HBV seropositive donors and should be screened among blood donors.
