Viral cause for chronic fatigue?

"Either [the virus] is a causative factor or it's a marker of patients who cannot clear the virus," linkurl:Eugene Kandel,;http://www.roswellpark.org/Research/Research_Staff/Kandel a molecular biologist at Roswell Park Cancer Center who was not involved in the study, told __The Scientist.__ The study doesn't distinguish between the two possibilities, he said. The virus, awkwardly named xenotropic murine leukemia virus-related virus (XMRV), may simply be a passenger, more prevalent in patients with underlying disease. Doctors and researchers still debate whether CFS is a disorder with physiological causes and what those causes might be....
