The study, published in the journal Science, shows that the virus, called murine leukaemia virus-related virus (XMRV), was found in 68 of 101 patients from around the US with chronic fatigue syndrome.

But the senior author of the study, Judy Mikovits, director of research at the Whittemore Peterson Institute in Reno, Nevada, said further blood tests have revealed that more than 95 per cent of patients with the syndrome have antibodies to the virus - indicating they have been infected with XMRV, which can lie dormant within a patient's DNA.

"With those numbers, I would say, yes, we've found the cause of chronic fatigue syndrome. We also have data showing that the virus attacks the human immune system," said Dr Mikovits. She is testing a further 500 blood samples gathered from chronic fatigue patients diagnosed in London.

"The same percentages are holding up," she said.

"We are confident that our results show there is no link between XMRV and Chronic Fatigue Syndrome, at least in the UK...."
