YOU WONT BELIEVE: Scientists uncover possible missing link between mono virus and multiple sclerosis - You Need To See This

For years, scientists have known that the virus behind "mono" dramatically raises the risk of multiple sclerosis (MS), a disease in which the immune system attacks nerve cells. But while most people are exposed to the mono virus by adulthood, only a few develop MS, raising the question of why.

Now, researchers have uncovered a possible reason why most people infected with the mono virus never develop MS: a specific immune-system gene may mediate their risk.
