title: [Multiple sclerosis in the Bashkortostan Republic and the Rostov region: a comparative epidemiologic study].
abstract: Epidemiological characteistics of multiple sclerosis (MS) in the Bashkortostan Republic (BR) and the Rostov region have been compared. Prevalence and incidence of MS were higher in BR (38.0 and 2.92 per 100 000) compared to the Rostov region (29.8 and 0.73 per 100 000). This finding may be explained by geographic and ethnic differences. The comparative analysis suggests that both environmental and genetic factors contribute to the etiology of MS.
