Virus Disproved as Cause of Chronic Fatigue Syndrome
The saga of the retrovirus XMRV and chronic fatigue syndrome appears to have ended, now that researchers in a federally funded study said they found no relationship between the retrovirus and the illness.
The controversy dates back to 2009, when a paper in the journal Science found a possible connection between chronic fatigue syndrome and XMRV. A retrovirus is a kind of virus that copies its own genes into a host’s DNA.
