I'm writing this post to see if anyone has any insight into abortive infections. Researcher Dr. Lehrner put forth the hypothesis that he felt SEIDs was actually the result of persistent infections (EBV, HHv6, CMV) that are difficult to diagnose because they can't replicate. I think this is an excellent theory. If someone has one infection during the period of time before antibodies are made then another different infection exposure then the combination would allow infections to spread more rapidly through the body. Once the body could make antibodies the spread of these infections should be checked however infected cells would still stay infected, be inflammed and painful which would be the source of the CFS symptoms. It is very common that EBV and other viruses stay dormant in the body after an initial infection. I think this is an excellent hypothesis for the cause of SEIDs.
