Chronic fatigue syndrome may be caused by a virus

Depression1Chronic fatigue syndrome is a disabling condition of prolonged and severe tiredness or weariness (fatigue) that is not relieved by rest and is not directly caused by other conditions, including fibromyalgia and depression. To be diagnosed with this condition, your tiredness must be severe enough to decrease your ability to participate in ordinary activities by 50%.

A study published last week in the journal Science suggested that a virus be the cause of chronic fatigue syndrome. An article published online Thursday in the journal Science reports that 68 of 101 patients with the syndrome, or 67 percent, were infected with an infectious virus, xenotropic murine leukemia virus-related virus, or XMRV, which probably descended from a group of viruses that cause cancer in mice.

Dr. Mikovits, research director at the Whittemore Peterson Institute in Reno said she and her colleagues were drawing up plans to test antiretroviral drugs — some of the same ones used to treat HIV infection — to see whether they could help patients with chronic fatigue. If the drugs work, that will help prove that the virus is causing the illness. She said patients and doctors should wait for the studies to be finished before trying the drugs.

If this syndrome is caused by a virus then I won’t be surprised because my symptoms with regard to both syndromes ie. chronic fatigue and fibromyalgia began after I had a prolonged respiratory virus (flu) that kept recurring.
