New Evidence that Chronic Fatigue Syndrome (CFS) Might be Linked to a Virus

Scientists from the National Institutes of Health have published a report showing a connection, but not necessarily a causal connection, between a known virus and Chronic Fatigue Syndrome (CFS). This was not a study designed to replicate the connection between XMRV and CFS, and in fact, no XMRV was found in the study subjects.

In a commentary accompanying the study, the University of Alberta’s Dr. Andrew Mason suggested that one way to settle the question would be to test anti-retroviral drugs in patients with CFS. Dr. Mason opined that if the CFS patients given anti-retrovirals improved a better connection could be implied, and that the benefits of such a study may outweigh the risks.

The results from the latest study were published online by the Proceedings of the National Academy of Sciences.
