[Epidemiology of multiple sclerosis in the province of Venezia (author's transl)].

In the province of Venice province on "prevalence day" (31 December 1974), the crude prevalence rate of multiple sclerosis was 20.44 cases/100,000 inhabitants (170 patients in a population of 831,657). The prevalence rate for men was 15.24/100,000 and for women was 25,41/100.000. In the city of Venice and in the near lagoon islands the MS prevalence rate was higher then that in the rest of the province, but there was no significant difference of age of onset, duration of the disease, initial symptoms and degree of disability between the two groups of cases. These results were compared with similar studies in other areas at the same latitude.
