Seroprevalence of HIV and hepatitis B and C virus in blood donors received at the Provincial Hospital of Moundou in Chad

Introduction: Blood transfusion is a medical act of great importance but blood can carry countless microorganisms such as hepatitis B and C viruses (HBV and HCV) and Human Immunodeficiency Virus (HIV) which are responsible for various pathologies. Methodology: We carried out a prospective study with an analytical aim from November 2023 to January 2024 among donors received at the blood bank Laboratory at the Provincial Hospital of Moundou (HPM) in southern Chad. The data from the interviews as well as the results of the tested blood bags were analyzed with R Studio software version 4.0.4.2021. Results: The study enrolled 539 donors, including 367 males and 172 females, that is to say sex ratio of 2.1. The mean age was 34.363 ± 8.668 years with extremes of 18 years and 55 years. The overall seroprevalence of HBV was 9.1%, 2.6% for HCV and 4.45% for HIV. Conclusion: The seroprevalence of hepatitis B and C as well as that of HIV remains high among voluntary and family blood donors. This situation remains worrying, hence the need for a new approach which will consist of retaining donors for quality blood.
