Trends in hepatitis B and hepatitis C virus seropositivity among blood donors over 15 years screened in the blood bank of a university hospital

Blood transfusion carries well defined risks including hepatitis B and hepatitis C virus transmission. In this study, records of blood donation candidates between the years 1996-2010 were retrospectively reviewed. A total of 220 841 apparently healthy adult donors were screened for hepatitis B surface antigen, anti-HCV with enzyme linked immunosorbent assay (ELISA) method. The overall prevalence of HbsAg and HCV were 1.07% and 0.39%, respectively. HBV seroprevelance decreased through years 1996-2010 but HCV seroprevelance showed a fluctuant course decreasing from 1996 to 2002. In order to decrease transfusion transmitted infections there should be centralized blood collection systems having qualified staff, equipment and non-remunerated voluntary blood donations must be strongly encouraged.
