Viral hepatitis is an important public healththreat for millions of people all over the world. Recently, some hepatitis viruses are detected. Hepatitis TT virus (TTV) is an unenveloped virus with a single-stranded, circular DNA genome of 3,818-3,853 nucleotides (nt) that infects humans and non-human primates (1). Recent reports indicate that TTV can be transmitted via blood/blood products (2). There are some previous reports on the prevalence of TTV-DNA among blood donors. The purpose of this study was to summarize the prevalence of TTV-DNA among transfusion-dependent thalassemia patients in the previous reports. This study was designed as a descriptive retrospective study. A literature review on the paper
