I am not sure but yes it does seem to be the culprit. The thing is many pathogens cause immune dysregulation and as one takes residense others find a niche to fill from that dysfunction and snowballs down from there so it is the dysregulation of the whole bodies microbiome that causes the dynamic variation in us all.So you've recovered after 40 years of illness, that's quite extraordinary! So are you saying that EBV was the cause of your illness? I haven't done much research on EBV, but I agree it could well be the at the root of the illness, at least for some people if not everyone.
The treatment I do brute forces homeostasis to over come the immune dysregulation and get the immune system to recognise and tackle more of these pathogens. It also puts your body in a more natural homeostasis state (healthly state).
