Everything I have read, they tend to think that a serious infection is the onset of MS, while it may not show up for years later. The infection throws your immune system into overdrive, and when it has attacked the heck outta what it should be, it turns on healthy cells.

The HHV 6 (usually known as roseola in infants to 2 years old) has been found in about 70% of post mortem MS brains. I am looking into that, because Ozone therapy can destroy that in your body, and they think having that can lead to relapses. My mom thinks I had roseola as a child. I also have scarletina, which is the mild for of scarlet fever, which is a strep. I had that when I was 14 or 15. The doc was surprised because he said that usually only happens in children as well.
