There seem to be associations between various other viruses and chronic conditions. Epstein-Barr virus seems to dramatically increase the risk of Multiple Sclerosis, likewise with Herpes and Alzheimer's. And of course HPV seems to cause various forms of cancer depending on where it occurs. I wouldn't be surprised if we come to the conclusion that certain conditions are effectively "long" forms of those viruses.
