Multiple sclerosis (MS) is a common, complex disorder. Associations of MS with Epstein-Barr virus (EBV) infection in Caucasian populations are well documented. However, in the Iranian population, previous studies have been conflicting. Sixty patients with MS and 50 healthy controls were tested for anti-EBV antibodies using chemiluminescent assays. All MS patients to be seropositive for EBV as compared to 82 % of controls (p = 0.0006). A strong, significant association of MS with EBV infection was documented, similar to studies in first world populations. Future studies should investigate the temporal sequence of infection to try to understand the cause of the recent increase in MS risk in Iran.

More logs for the fire and confirms studies in other places that most people in the population have been exposed to EBV but virtually all MSers have.
