HHV-6 Foundation
Introduction
HHV-6 is an infection that can persist in the brain tissue long after the primary infection and after evidence of the virus has long disappeared from the plasma in the circulating blood. Therefore, direct evidence of chronic infection is not easily attainable by standard laboratory tests, even though it has long been suspected as playing a role in chronic fatigue syndrome (CFS), in conjunction with Epstein Barr Virus (EBV) the virus that causes mononucleosis.
