You are right despite what other HNers think. MS is first and foremost an auto-immune disease. It is not that surprising that infections that provoke a large immune response can trigger an autoimmune condition. When we understand the immune system better, especially around the early stages of response to a potential pathogen, we'll understand how auto-immune disease starts and is maintained. EBV has long been a putative risk factor for MS, but given 95% of the population will have EBV, it clearly only goes some way to explaining how MS comes about.
