Can you get the JC virus (infection) even if you don't have MS?
J.C. Virus is ubiquitous, meaning that is located throughout the environment and nearly everyone is exposed to the virus at some point in their life; researchers estimate that the virus resides latently in the kidneys and certain bone marrow cells in up to 90% of adults. This virus has no special relationship to MS patients.
