mrpanoff,
Interesting. What lab was used for your serum polio antibodies? Was there a reference range? Viral reactivations tend to decline in intensity levels after the sudden onset. they do their damage to the immune system and fade back into the woodwork. How long ago was your onset?
It was Rospotrebnadzor lab in Moscow, a sanitary inspection authority. There was no strict reference range. They told me up to 1/256 can be observed in healthy individuals. There was a problem with polio type 1 results as they didn't do dilutions properly at first and gave me a result of 1/>32. However, upon my insistence they did further dilutions and proclaimed 1/32 as the final result.
The onset was more than 2 years ago.
All in all, together with the negative PCR (detects common sequences between ECHO, Polio, Coxsackie) it doesn't look like an enterovirus, for me at least.
This doesn't rule out the possibility of Polio vaccines of the past having been contaminated, hence the reported coincidence between Polio and ME outbreaks.
