    Scientists Discover How the 'Mono' Virus Might Trigger MS

    A one-two punch from science has clearly tagged the mononucleosis virus, Epstein-Barr, as a major cause of multiple sclerosis.

    The Epstein-Barr virus (EBV) appears to trigger multiple sclerosis (MS) by tricking the immune systems of some into attacking their body's own nerve cells, a new study indicates.

    Too Soon to Tell if Omicron Will End Pandemic: Fauci

    It's too soon to determine whether Omicron's rapid spread will turn a pandemic virus into an endemic disease, America's top infectious disease expert says.
