"When the journal Science published an attention-grabbing study last fall linking chronic fatigue syndrome to a recently discovered retrovirus, many experts remained skeptical — especially after four other studies found no such association.

Now a second research team has reported a link between the fatigue syndrome and the same class of virus, a category known as MRV-related viruses. In a paper published Monday by The Proceedings of the National Academy of Sciences, scientists found gene sequences from several MRV-related viruses in blood cells from 32 out of 37 chronic-fatigue patients but only 3 of 44 healthy ones."
