In October 2009, a Science report that patients with chronic fatigue syndrome (CFS) were infected with XMRV attracted a great deal of attention, but subsequent studies could not confirm this finding. Now, a new study in the 22 September edition of ScienceExpress reports that the lab tests used to detect the retrovirus called XMRV in patients with chronic fatigue syndrome are unreliable. The study is accompanied by a partial retraction of the original Science paper.
