ABSTRACT

The Epstein-Barr virus (EBV) is a member of the herpesvirus family that infects more than 90% of the world’s population. The consequences of infection with this virus depend on age and degree of immunocompetence and can lead to a broad spectrum of disease manifestations, from a subacute febrile illness with pharyngitis and lymphadenopathy to viral encephalitis, to posttransplant lymphoproliferative diseases (PTLDs).
