I just had this page pop up http://www.facebook.com/CFIDSAssn/posts/321539687107 with the following content: DHQP AtoZ Listing including XMRV: http://www.cdc.gov/ncidod/dhqp/a_z.html XMRV Overview/Main Content Page: http://www.cdc.gov/ncidod/dhqp/bp_xmrv.html XMRV Q&As: http://www.cdc.gov/ncidod/dhqp/bp_xmrv_qa.html My heart jumped, thinking it was news of replication studies, but I didn't find anything significant after a quick look (hence my understated thread title). What they're saying might be of interest though, and I've not seen them linked to from here before. edit: Just read more. It's all still vague 'ongoing studies...' etc, but reading between the lines, it doesn't sound like they're too worried at this point. They could be trying to avoid public panic, or it could be that their work isn't supporting the WPI's.
