ABSTRACT: Introduction: The risk of transmission of pathogens such as hepatitis B virus threatens the safety of transfused patients especially in high endemic areas. The aim of this study was to determine the incidence and factors associated with hepatitis B virus surface antigen (HBsAg) seroconversion in blood donors at the Regional Blood Transfusion Centre of Ouagadougou. Methods: A retrospective cohort study of voluntary non-remunerated blood donors (VNRBD), was conducted from 2008 to 2017. Data on HBsAg seroconversion were collected. The Kaplan-Meier method and the Log-Rank test were used to estimate the survival curves. Cox’s regression identified the factors associated with this seroconversion. Results: Of 23,494 donors, 559 had HBsAg seroconversion. The number of donor years was 58,637.50 and the HBV incidence rate was 9.53 per 1000 donor years. The median seroconversion time was 75.73 months with extremes of 2.7 months and 107.12 months. The risk of seroconversion was 1.30 times higher among donors aged 21 to 24 years old (p = 0.007) and 2.49 times higher among those over 24 years old (p Conclusion: The incidence of HBsAg remains high among blood donors, which could have a negative impact on transfusion safety. The age of the blood donor was significantly associated to AgHBs seroconversion.
