For decades, millions living with multiple sclerosis have carried an unanswered question alongside their diagnosis — why them, why this, why now. A sweeping Harvard study, drawing on blood samples from over ten million U.S. military personnel, has moved science closer to an answer: the Epstein-Barr virus, a near-universal human companion, appears to be a causal trigger for MS in those genetically or environmentally predisposed. The finding does not yet offer a cure, but it offers something the afflicted have long been denied — a reason that lives outside the realm of personal fault.
