From the CDC website:
It was first identified in samples of human prostate cancer tissue. Some additional studies have suggested that a high percentage of persons with chronic fatigue syndrome (CFS) may be infected with XMRV, but this result needs to be confirmed by other groups of scientists.
OK, maybe I'm reading too much into this, but isn't it interesting that the CDC writes "...STUDIES [plural] have suggested that a high percentage of persons with chronic fatigue syndrome (CFS) may be infected...." In fact, only ONE study has suggested that--unless the CDC knows about other positive studies in press!
The other thing that stood out to me is the CDC's statement that the result needs to be confirmed by other GROUPS (plural). Notice that the prostate cancer association was only confirmed by ONE group (Singh's group corroborated Silverman's findings). Yet the CDC doesn't say that more groups need to replicate it before it'll be taken seriously. For prostate cancer, one replication is enough, apparently.
So if the CDC uses the same standard for CFS, one independent positive study is all we'll need! :victory:
But of course, there's always a double standard for the ugly stepsister. :Retro mad:
