Prevalence and trends of hepatitis B virus, Hepatitis C virus, Human immunodeficiency virus 1, 2 and syphilis infections among blood donors in a regional transfusion center in Punjab, India: A 3 years study

Background: Accurate estimates of the risk of transfusion-transmitted infectious diseases are essential for monitoring the safety of blood supply and evaluating the potential effects of new screening tests. Objective: The aim was to determine changes over time in blood donor population infection rates of hepatitis B virus (HBV), hepatitis C virus (HCV), human immunodeficiency virus (HIV-1, 2) and syphilis. Materials and Methods: Changes in rates of HBV, HCV, HIV-1, 2, and syphilis infections were evaluated by comparing yearly prevalence rates for blood donors over 3 years, that is, between January 1, 2012 and December 31, 2014. Serological tests were done according to the standard operating procedures and manufacturer's instructions and included the following: tests for hepatitis B surface antigen; antibodies to HCV and HIV-1, 2 and rapid plasma reagin test for syphilis. Results: Nearly 2.54 of the total screened blood donors were reactive for one of the four transfusion transmitted infections (TTIs) with higher prevalence in replacement (3%) than voluntary donors (2.3%) and in male (2.54%) than female (2.3%) donors. TTI tend to be more (54.7%) in younger population of 18-30 years. HCV infection is the most common of all TTI (50%). Conclusion: The rising prevalence rates of HIV; HBV; HCV and syphilis among different groups suggests that blood transfusion is still very unsafe in this community and emphasis should be laid on donor education and donor self-exclusion, implementation of strict donor screening criteria, pre-donation counseling, and more sensitive screening methods. Furthermore, donors with a history of sexually transmitted infections should be totally excluded from all donations.
