Seroprevalence of Transfusion Transmitted Infection among Blood Donor at a Tertiary Level Hospital of Bangladesh: One Year Retrospective Study

Background: A transfusion transmitted infection (TTI) is an infection that is transmitted from person to person through parental administration of blood and blood products. The magnitude of transfusion transmitted infection (TTI) varies from country to country depending on TTI’s load in that particular population. Measuring their severity their severity WHO (World Health Organization) has recommended pre transfusion blood test for Human Immunodeficiency virus (HIV), Hepatitis B Virus (HBV), Hepatitis C virus (HCV) and Syphilis as mandatory. The aim of the study was to assess the trend and prevalence of TTI among blood donors in BRB Hospitals Limited. Method: A retrospective cross-sectional study was conducted by reviewing the record from 2022 to 2023 at BRB hospitals limited Transfusion Medicine department. All blood donors who presented to the blood bank and screened for TTI during study period were included. Data was collected, entered and analyzed using Microsoft Excel 2007. The descriptive statistics were determined in means of percentage. Chi- square was used for trend analysis and p-value was used to declare the statistical significance between variable. Result: The study included a total of 5074 donors-4,920 (97%) male and 154 (3%) female. Of them 3,840 (76.3%) were directed donor while 1,204 (23.7%) were replacement donor. An overall TTI prevalence rate of 0.95%. The prevalence of HBV, HCV, HIV and Syphilis was 0.5%, 0.1%, 0.07% and 0.2%. Conclusion: Methods to ensure a safety blood supply should be encountered. For that screening with a better selection of donor and used of screening tests including nucleic acid testing technology should be implemented.
