Is Diabetes type 1 autoimmune? I thought it was genetic. I have type 2 as a result of an unknown severe virus, in hospital a week, every lab test & imaging studies, nothing was revealed except sky high C reactive protein level, fever 40°C (105°F) for over a week, in 2006. After that virus, a constant downhill for my entire body, in a wheelchair now, interstitial lung disease, over a dozen ai diseases, many rare, degenerative disc disease, spontaneous broken vertebrae, in constant pain.
