I just want to tell you that I agree with the virus issues as being a trigger for auto immune diseases. I fully believe that. I was 29, some virus put me in the hosptial ER. Flu it was labled. While labled and on the table receiving fluids, my body began to tingle. My hair stood on end, and I can remember thinking, that I was worried it would do something to my hair. Six weeks later my hair dropped out in clumps. I have alopecia universalis now since that age. I have added four other immune diseases. My diseases intensified in 2001 with type A Asian Flu, picked up on a cruise. All my conditions worsened after that episode. I have not had my health since my origional problem at the age of 29. I am now 60, and struggle with all the issues I have. The medical community is exploring this with monal clonal antibiodies. That is as far as I got with research when I quit a trial study. I do not have PD, but I do recognize that as being in the immune problem catagory. ginnie
