More evidence Epstein-Barr triggers MS

Patients with signs of the virus have a 32-fold increased risk of developing multiple sclerosis, a large US study shows

New research offers the strongest evidence to date that the Epstein-Barr virus may trigger some people to develop MS.

In one of the largest studies yet to back the theory, US researchers found the risk of MS increased 32-fold following Epstein-Barr infection.

They tracked blood samples from more than 10 million people in the military stored from 1993 to 2013, hunting antibodies signalling viral infection.
