I'm open to the idea that entero virus can be a factor as a trigger to the development of symptoms. This seemed to be the case for my onset. Mine was noravirus. However from what I have picked up it seems that there are more than one type of trigger and he seemed to want to find one answer. I'm more interested in what makes people susceptible in the first place and once you've got it how do you treat to make a full recovery. In my case I was definitely depleted of vitamin b6 folate and b12 before I got ill. Like for 10-15 years before. So my methylation was disfunctional/vulnerable before I got my trigger. I think there is more to it, and studying triggers is a good thing although it seems over simplistic to blame everything on a type of virus. Just my take on it....seems like a nice man though.
