Expert raises contamination issue in unresolved XMRV-CFS findings

British retrovirologist Robin Weiss said that with the question on the link between the XMRV retrovirus and chronic fatigue syndrome still unresolved, reassessing whether contamination is the problem might help. Weiss said there have been cases before in which studies would associate a certain virus to a disease only for researchers to discover later that the results were false because of contamination. Weiss said he faced the same problem in 1997, when his team found a rheumatoid arthritis virus link, which later turned out to be a contamination from a rabbit retrovirus. Los Angeles Times
