Hi Eric=-
Cort has given an excellent overview of all the components of CFS/CFIDS/ME scattered throughout the website, so in answer to your question.....Yes...this issue has been discussed before on this forum. I disagree with you that you need XMRV to develop CFS......only because I believe there are 3-7 subsets of this disease. I know for sure of 2 subsets. One is A) Virally Induced with viral reactivation and the other B) shows no viral reactivation. It is the same in GWI, Autism, MS, Lupus, ALS, etc.....only a percentage of patients are showing XMRV Positive although they all are diagnosed with the disease. I keep thinking that a smoldering aspect in all of this is HHV-6A. I've heard it said that HHV-6A may be the fuel that ignites to the fire of Death for AIDS patients. Genes, a plethora of viruses, a multitude of co-infections, STRESS factors, cytokines, TNF and XMRV and hormones and auto immune diseases all play a part in this maze of CFS. Figuring out the subsets may fully never happen. And like Human T=Cell Lymphoma (retrovirus), how it is spread may never be fully understood....transmission is key because this puts us all at risk. Sadly, there may be more treatment options for success for some subsets than others. Horrifying.....
