Multiple sclerosis (MS) is a chronic autoimmune disorder that attacks the central nervous system. For years, Epstein-Barr virus (EBV) has been strongly linked to MS, as nearly every person diagnosed with the condition shows evidence of past EBV infection. For example, a 2022 study analyzed millions of U.S. military recruits and found that getting infected with EBV increased a person's risk of developing MS 32-fold.
