Background: Hepatitis B virus is one of the transfusion transmissible infections. Despite the availability of hepatitis B virus (HBV) vaccine and screening tests but still danger of virus transmission via blood transfusion is high in some regions. The objective of this study was to determine the trend of seroprevalence of hepatitis B in over an 11‑year period (2005–2015). Methods: In this study, 355,083 blood donors were estimated for hepatitis B surface antigen (HBs Ag) seropositivity during 2005–2015 who referred to blood infusion centers of Lorestan province. Third‑generation ELISA method was used to detect HBs Ag. Results: The prevalence of HBs Ag in blood donors was 0.29% (1017). It was decreased steadily from 2005 to 2015 (0.68% to 0.12%) but increased in 2008 year. The trend prevalence of HBs Ag seropositivity significantly decreased over the study period (P < 0.001). The decline in HBV infection rates was more prominent in regular and repeated donor’s groups compared to people who donated blood for the first time (P < 0.001). Conclusions: The result of present study was indicated, Lorestan city in west of Iran can be classified as a low‑income region because the low prevalence of HBs Ag in blood donors. Also the prevalence of HBs Ag in first‑time donors was higher than other groups.
