The stormy debate over a potential cause of chronic fatigue syndrome (CFS) is nearing hurricane force. Last month, it prompted headlines suggesting that researchers have reached a dead end, scores of blog posts from disappointed patients, and accusations that scientists had gone beyond their data. The 14-month-old row intensified when four papers appeared in Retrovirology suggesting that reports linking the virus XMRV to CFS were based on false positives. The debate began in 2009 with a report in Science that XMRV, a retrovirus recently reported to have been found in prostate tumors, had been detected in 67% of a set of CFS patients but in only 4% of controls {Science, 9 October 2009, p. 215). Since then, one other group has found XMRV-like viruses in CFS patients' blood. But several teams have failed to detect the virus in CFS or cancer patients or in healthy people. Researchers have struggled to explain the discrepancies {Science, 17 September 2010, p. 1454).
