There was a new study done and it also witnesses that a virus called XMRV causes chronic fatigue syndrome.

In the year 2009 US scientists found this situation. It is named as ME. In this there is a mouse-like virus which is seen in blood samples.

But now, UK experts held that this detection was an artificial positive. It happened because of the cross defect in the lab.

They alleged that this virus may cause illness but still their no such strong proof for this.

Professor Greg Towers directed the research. He is a Wellcome Trust senior research fellow at University College, London. He concluded that chronic fatigue syndrome is not caused by the XMRV. XMRV means xenotropic murine leukemia virus-related virus, it is a virus seen in mouse DNA.

He added that chronic fatigue syndrome is caused by a virus. But it is yet to be found and they are sure that this virus, XMRV is not responsible for this disease.

This was detected in the year 2006 and then later it was also seen in the samples of the patients who were suffering from prostate cancer and chronic fatigue syndrome.
