| Abstract: | The materials on the epidemiological supervision of poliomyelitis in a large city, carried out in 1972-1981, are presented. Two periods differing in morbidity rate, in the level of population immunity to poliomyelitis and in the activity of the poliovirus circulation are defined. The supervision of poliomyelitis is shown to be capable of influencing the course of the epidemic process of this infection provided that the individual elements of such supervision are correctly evaluated in different epidemic situations. |
