Gerwyn : So I'm understanding that you are pretty confident XMRV could cause CFS based on this science paper? That's awesome news! I'm just wondering why my girlfriend didn't have CFS after 9 years together and me being sick for 5 years (at least), is it essential to have an already weakened immune system to let it take control of our bodies? (I had some vitiligo since childhood and hashimoto thyroiditis for a long time too and I'm wondering if autoimmune diseases are a consequence or rather the a determinant factor that leave the door open to XMRV). Would like to know your thoughts on that, thx!
