Just-released study detects variants of the retrovirus XMRV in most CFS patients.

Patients, physicians and virologists have been anxiously awaiting the Proceedings of the National Academy of Sciences (PNAS) paper on Chronic Fatigue Syndrome and the retrovirus XMRV. The paper, “Detection of MLV-related virus gene sequences in blood of patients with Chronic Fatigue Syndrome and healthy controls,” was published today. In it, the authors state that their conclusions “clearly support” the October 2009 Science paper linking a retrovirus to the neuroimmune disease Chronic Fatigue Syndrome (CFS), which afflicts 17 million people worldwide, 1 million of them in the U.S. The retrovirus XMRV has also been linked to a virulent form of prostate cancer.
