Abstract

Blood transfusion is one of the essential therapeutic methods. In Thai Binh, the voluntary blood donation program has developed significantly. Therefore, the process of selecting blood donors and screening blood products must be rigorously controlled, especially with regard to infectious diseases, including Hepatitis B and Hepatitis C. Objective: Describe the characteristics and prevalence of HBV and HCV infections, and to identify some factors associated with the prevalence of HBV and HCV infections among voluntary blood donors in Thai Binh province during the period 2021-2024. Subjects and Methods: A cross-sectional, retrospective descriptive study was conducted, analyzing stored records of HBV and HCV screening test results using serological methods and NAT assays from 28,806 voluntary blood donors who participated in voluntary blood donation programs across Thai Binh province between 2021 and 2024. Results and Conclusion: 1) The positivity rate for HBsAg using the ECLIA method was 1.0%, and the positivity rate for anti-HCV using the ECLIA method was 0.7%. The age groups 41-50 and 51-60 exhibited the highest HBsAg positivity rates, both at 1.5%. Similarly, these age groups showed an HCV positivity rate of 1.0%. Repeat blood donors had higher positivity rates for HBsAg and anti-HCV at 0.7% and 1.1%, respectively, compared to first-time blood donors, whose rates were 0.5% and 0.4%, respectively. 2) NAT Testing: The HBV-DNA positivity rate in 28,506 blood samples was 0.07%; no samples tested positive for HCV-RNA.
