Abstract
ObjectivesPrevention of blood transfusion-transmitted infections includes blood donor screening and effective infectious markers screening for donated blood. This study had two main objectives: to determine seroprevalence of HBV, HCV, HIV and syphilis in blood donors of the Yaoundé Central Hospital and to study sociodemographic factors of blood donors. Patients and methodsA retrospective study of consecutive blood donors’ records from January to December 2013 was conducted. Seroprevalence of hepatitis B, hepatitis C, human immunodeficiency viruses and syphilis were determined in 9024 whole blood donations collected in the Yaoundé Central Hospital in the centre region, Cameroon using Elisa kits. ResultsMean age of donors was 28 years. The male to female ratio was 14.8. Most of blood donors were replacement donors (97.2%) and first-time donors (76.8%). Up to 19.3% of the donors tested positive for at least one infectious agent, in which 0.1% presented a positive test for three viruses (HIV, HCV and HBV). The overall seroprevalence in blood donors was 12.6% for HBsAg, 3.2% for hepatitis C antibody, 3.3% for HIV-1/2 antibodies and 0.2% for syphilis. The prevalence of HBsAg was significantly higher in men (P=0.001), among first-time donors (P=0.003), in blood group A (P=0.01) and those with the rhesus positive blood (P=0.01). The prevalence of anti-HCV was significantly higher among first-time donors (P=0.05). The prevalence of anti-HIV was significantly higher in first-time donors (3.7% vs 2.2%, P=0.02). ConclusionFirst-time blood donors and replacement donors are the two types of donors in Cameroon. Replacement donors are considered as having a major risk of transmission of infections to recipients. The seroprevalence of HIV, HBV, HCV, and syphilis among these donors is high and reflects how much these agents are present in Cameroon. Effective infectious markers screening and organization of blood donors into an association of volunteer's donors are necessary to secure blood transfusion in Cameroon.
