Is there a study part in this (no access yet) or is it an article, spreading the word to doctors? So many people, even patients say another virus, they don't want to hear about it. Could neurotoxic envelope proteins on the XMRV be related to the proteins that Baraniuk is finding in spinal fluid? I'm at the page in Osler's web where viruses are budding all over the CDC lab from contamination, possibly from a patient's spinal fluid. Maybe de Frietas's virus was the epidemic one, and XMRV in the CFS patients from Atlanta. Sorry about the speculation, I'm thinking class action suit. One theory about HIV or ebola is that encroaching on the forests brought us closer to the monkeys.
