Background: Hepatitis B virus (HBV) is one of the most common infectious pathogens worldwide particularly in sub Saharan African (SSA). In Cameroon, HBV is highly endemic (HBsAg >8%), suggesting a rigorous transfusion safety policy on the national territory. This study aimed to determine HBs antigen (HBsAg) seroprevalence of the HBV in blood donors using Enzyme Linked Immunosorbent (ELISA) at the Essos Hospital Centre (EHC) in Yaounde, Cameroon. Methods: From January, 18th to May 31st, 2021, we carried out a quantitative, cross-sectional and descriptive study among 326 volunteer blood donors attending EHC of Yaounde, Cameroon. The socio-demographic data of the participants was described while the surface antigen of hepatitis B virus (HBsAg) was determined using qualitative ELISA (Rapid Labs HBsAg) technique in the sera or plasma. The data was analyzed using the IBM Statistical Package for the Social Sciences (SPSS) v. 22. The difference between two proportions was considered significant when the probability of error was less than 0.05 (p |
