Chronic fatigue Syndrome may be r/t viral infection

Dr. Mikovits and researchers from the National Cancer Institute and the Cleveland Clinic reported in Science that 68 of 101 patients with chronic fatigue syndrome, or 67 percent, were infected with XMRV, compared with only 3.7 percent of 218 healthy control subjects. Further testing after the paper was written found the virus in nearly 98 percent of about 300 patients with the syndrome, Dr. Mikovits said.

She said she believed that the virus would eventually be found in every patient with chronic fatigue syndrome. XMRV affects the immune system, can probably cause a variety of illnesses and may join forces with other viruses to bring on the syndrome, she said.
