In the winter of 2009, we aired a segment reporting on the connection between the XMRV retrovirus and its presence in patients suffering from chronic fatigue syndrome (CFS). These findings were first published in the prestigious journal Science in the fall of 2009. At the time of our show, many doctors and patients were optimistic that scientists had finally found a virus that causes CFS.
As is the nature of science and medicine, our knowledge about XMRV and CFS continues to evolve. Today, Science has released new research showing that subsequent studies could not confirm the link between XMRV and CFS. For more information on these new findings, visit http://www.sciencemag.org.
