Background
The risk of infection by transfusion-transmitted viruses has been reduced remarkably. However, a zero-risk blood supply is still desirable. Hepatitis B (HBV) and Hepatitis C (HCV) viruses are transmitted mainly by parenteral route, following which, a remarkable proportion of infected cases, may progress to chronic hepatitis. In this study we analyzed seroprevalence, demographic and epidemiologic characteristics of positive HBV and HCV cases in first time blood donors of Bushehr province.
