Some qualitative changes of indicators of the epidemiological position as regards tuberculosis in Czechoslovakia and...

The application of comprehensive provisions in TB control in Czechoslovakia led to a marked decline of its quantitative and qualitative epidemiological indicators. The incidence of TB declined from 191.1 in 1951 to 46.3 in 1978 per 100 000 population. The number of newly detected cases of TB in child groups declined between 1958 and 1978 from 78.2 to 5.5 per 100 000 children. The number of cases of tuberculous meningitis declined during this period in the entire population from 97 to 5 cases. There was a markes shift of newly detected cases into higher age groups. The prevalence of bacillary TB decline from 211.1 in 1956 to 39.0 in 1977 per 100 000 population. According to mathematical and statistical calculations the incidence of TB will preserve also in future its declining trend whereby the values at the turn of the century will be at the borderline of the lower half of the value recorded at present.
