About this trial
Immunocompetent subjects with high load of Epstein-Barr virus DNA (EBV-DNA) in peripheral blood will be enrolled and prospectively followed up to track the natural histories of the chronic high load of EBV virus. The primary goal of this study is to explore the association of peripheral high load of EBV with the hematological malignancies, and second goal is to investigate the genetic mechanisms of immune escape and tumorigenesis of chronic EBV infection.
