[The results of monitoring enterovirus circulation circulation among the population and in the environment of Tula Province over 10 years (1985-1994)].

The study of the isolation rate of polioviruses and other enteroviruses in patients with different diagnosed diseases, among healthy child population, as well as the circulation of these viruses in the environment was carried out on the territory of Tula Province for the period of 1985-1994. The epidemiological analysis of the data obtained in this study are presented. The study revealed that the vaccinal prophylaxis of poliomyelitis, carried out for the period of many years, did not lead to the elimination of poliovirus strains, differing in their genetic properties from vaccine strains, on the territory of Tula Province.
