[Experience in dividing Tyumen Province into districts according to typhoid morbidity based on sanitary demographic factors].

For the first time the territory of Tyumen Province has been zoned according to situation in typhoid fever morbidity by means of a complex of methods for computerized statistical data processing in combination with extensive epidemiological analysis. As a result, 43 administrative districts have been grouped in 5 zones having similar epidemiological, sanitary, hygienic, and demographic characteristics. For these zones territorially differentiated measures for decreasing typhoid fever morbidity have been worked out.
