Seroprevalence, trends, and risk factors of hepatitis B and C among family replacement blood donors; a 7-year retrospective study at Sunyani Municipal Hospital, Ghana

Abstract Background Hepatitis B and C cause chronic infections which develop into liver-related sequelae, like cirrhosis and liver carcinoma. This study determined the prevalence, trends, and risk factors of HBV and HCV among family replacement blood donors. Methods A retrospective review of primary data on blood donors screened between January 2015 and December 2021 was conducted at the Sunyani Municipal Hospital. The data were assessed for seroprevalence, trends, and odds ratios using SPSS. Results Of 6847 donors, the majority were males (88.1% [6033]), ≤ 24 years (27.4% [1874]), of the O blood type (69.8% [4776]), and Rh-positive (89.9% [6154]). Seroprevalences of HBV and HCV were 3.2% and 1.9%, respectively, with more males infected with both HBV and HCV (3.4% vs 2.0%). Male donors were 2.842 times (CI: 1.500-5.385, p = 0.001) and 2.399 times (CI: 1.116–5.157, p = 0.025) more susceptible than females to HBV and HCV, respectively. In the rainy season, donors were 1.489 times (CI: 1.017–2.180, p = 0.041) more susceptible to HCV. HBV and HCV showed declining trends over the period (slope: -0.5464, p ≤ 0.001 vs slope: -0.6179, p ≤ 0.001). Conclusion Gender was significantly associated with both HBV and HCV, while season was significantly associated with HCV. The male gender and rainy season were significant determinants of both infections. The seroprevalence of HBV was higher than HCV despite the significant decline in both HBV and HCV seroprevalences. We, recommend health authorities intensify health education among males and during the rainy season. Also, local variations in the seroprevalence of these infections call for upgrade and standardisation in serological testing for blood donors across Ghanaian blood centres.
