Epidemiological characteristics of diphtheria morbidity in the Republic of Tatarstan in 1994
Before the introduction of planned vaccination against diphtheria in Tatarstan, the number of diphtheria cases per 100 thousand people was 25.3 in 1920-1929 - 25.3, 1930-1939 - 66.5, 1940-1949 - 75.4, 1950-1959 - 67,2. Planned vaccination, which began in 1955-1956, contributed to a decrease in the number of cases. Over the following decades, the average incidence rate per 100,000 population steadily decreased and was in 1960-1969 - 5.2, 1970-1979 - 0,07. However, in 1982-1985 there was a slight increase in the number of diphtheria cases, so the average morbidity rate for 1980-1989 slightly increased (0.09 per 100 thousand population).
