RT Journal A1 Kuehn BM T1 STudy reignites debate about viral agent in patients with chronic fatigue syndrome JF JAMA JO JAMA YR 2010 FD October 20 VO 304 IS 15 SP 1653 OP 1656 DO 10.1001/jama.2010.1421 UL http://dx.doi.org/10.1001/jama.2010.1421 AB A study linking chronic fatigue syndrome (CFS) in humans to a family of retroviruses that cause leukemia in mice appears to validate a controversial study published last fall. But far from settling the debate about the role of viruses in the disease, the new findings raise a host of questions about why other scientists, including a team from the US Centers for Disease Control and Prevention (CDC), have failed to find such a link, and about the potential clinical and public health implications. The study was published in August in the Proceedings of the National Academy of Sciences (Lo S-C et al. Proc Natl Acad Sci U S A. doi:10.1073/pnas.1006901107 [published ahead of print August 23, 2010]).
