Thanks for these - don't have an opinion on either but will look into. Broadly, I think immune dysfunction is a feature of most cfs so there is often a positive EBV test, or HSV test. I suspect this is more "downstream" than causative of CFS. However, it may be that there is a biomarker in the mitochondrial function, bone marrow etc...I hope one is found!
