Epidemiological survey on multiple sclerosis in Italy.

An epidemiological survey on Multiple Sclerosis was carried out in 1975 with similar methods in 9 italian provinces: 4 in the North, 2 in central Italy and 3 in the south and islands. It was found that the incidence of the disease was partically uniform in the northern provinces, in the central Italy and in Bari province. It is important however to complete in greater detail such survey in the south of Italy where the data are still incomplete.
