There are continuing signals that the Epstein-Barr virus (EBV) is a fuel that can spark a multiple sclerosis (MS) fire. EBV is a herpes virus that causes infectious mononucleosis, more commonly known as mono. Sometimes called the “kissing disease” because the virus that causes it is easily spread through saliva,…

Mono as Child or Teenager Tied to Risk of MS as Adult in Large Study There’s been a lot of buzz about this study, but I don’t think anyone should be surprised about its results. For years, researchers have suspected a link between the Epstein-Barr virus (EBV) — the…

People who contract infectious mononucleosis — colloquially known as “mono” — during childhood or adolescence are at a roughly two to three times greater risk of developing multiple sclerosis (MS) as adults, a large population-based study suggests. Notably, the study points to mono itself — independent of other factors…

Ublituximab, Potential Relapsing MS Therapy, Up for FDA Approval Like Ocrevus (ocrelizumab) and Kesimpta (ofatumumab), ublituximab targets the CD20 protein that’s found on the surface of B-cells in the immune system.
