For the nearly 1 million Americans who suffer from chronic fatigue syndrome, they may want to note a new study that reports the disease is not caused by the XMRV and pMLV viruses, as previously thought.
Health Day reports researchers from Columbia University, the National Institutes of Health, and other key institutions "examined 147 patients with chronic fatigue syndrome from sites across the country and compared them to 146 healthy patients."
The much anticipated results found "no link between the illness, also called myalgic encephalomyelitis, and mouse leukemia retroviruses, including one called XMRV." Studies have previously found those with chronic fatigue syndrome had high levels of the virus, as scientists looked for the cause of this mysterious disease.
Women often suffer in higher proportion from the illness, which also affects memory and causes some joint and muscle pain, according to Health Day.
