[The epidemiological characteristics of the spread of Grigor'ev-Shiga dysentery in the territories of the former USSR in recent years].

On the basis of special data on the registered cases of Grigor'ev-Shiga dysentery on the territory of the former USSR the spread of this nosological form of Shigella infections since 1980 until the present moment has been analyzed. As shown by this analysis, Grigor'ev-Shiga dysentery is not widely spread on the whole territory of the former USSR, the cases of this disease being mostly registered in Namangan (the Uzbek Republic). The study has shown that the area of the circulation of Shigella dysenteriae 1 is not completely determined. This disease is quite widely spread in some areas of Central Asia, penetrating from these areas to other regions. Everyday contacts have shown to play the main role in the transmission of S. dysenteriae 1 due to poor municipal sanitation facilities and pronounced deficiency in the level of general and sanitary education. The withdrawal of Soviet troops from Afghanistan has led to the rapid improvement of the epidemiological situation on the territory of the former USSR as the result of a sharp decline in the "import" of Shigella dysenteriae 1.
