In October 2009 it was reported that 68 of 101 patients with chronic fatigue syndrome (CFS) in the United States, when tested, were infected with a novel gamma retrovirus, xenotropic
murine leukemia virus-related virus (XMRV) (Lombardi et al., 2009). XMRV is a recently
discovered human gammaretrovirus first described in prostate cancers that shares
significant homology with murine leukemia virus (MLV) (Ursiman et al., 2006). It is known
that XMRV can cause leukemias and sarcomas in several rodent, feline, and primate species
but has not been shown to cause disease in humans. XMRV was detectable in the peripheral
blood mononuclear cells (PBMCs) and plasma of individuals diagnosed with CFS
(Lombardi et al., 2009). After this report was published there was a great deal of uncertainty
surrounding this emergent virus and its involvement in the etiology of CFS. The uncertainty
was, in part, due to CFS being a complex, poorly understood multi-system disorder with
different disease criteria used for its diagnosis. CFS, also known as Myalgic
Encephalomyelitis (ME), is a debilitating disease of unknown origin that is estimated to
affect 17 million people worldwide. The initial report connecting XMRV to prostate cancers
and CFS garnered significant media and scientific interest since it provided a potential
