Thanks, Irat, that was most interesting. I knew about many of the outbreaks but not all of them. This seems to come and go as the winds blow, doesn't it. One of the reasons it's so hard to track down an actual case, if indeed there is just one causes (which I personally doubt). But my input doesn't matter, it's the input of researchers and scientists, isn't it? The symptoms are so diverse....no wonder an ordinary doctor can't put it together, but as I've remarked on before, he can be kind and understanding of those who suffer what was delivered to our doorstep(s). Yours, Lenora.
