Epstein-Barr Virus (EBV) is best known for causing mononucleiosis, or the 'kissing disease,' in teenagers. Almost all adults get EBV at some point in their lives, even if they don't get mono. New research shows that EBV infection may have longer-lasting impacts. Using data from the American military, researchers now show that EBV infection drastically increases an individual's risk for multiple sclerosis, a debilitating autoimmune disorder. In this episode, Dan and Derek discuss how these researchers figured this out and potential ways to prevent EBV infection (and potentially multiple sclerosis) altogether.Bjornevik et al.
