The authors report on tuberculosis situation in the Czech Republic (CR) in 1989 and compare the data with 1988. The incidence of all cases of respiratory TB was 15.5 and that of bacteriologically confirmed cases 11.1/100,000. The mortality from TB was also low (1/100,000). Two-thirds of the patients were detected because of the patients' complaints. This passive case - finding was, however, inadequate in subjects with a poor health consciousness. Active screening was restricted to subjects with a high risk of TB (in contact with tuberculosis, with different diseases, with socio-economic factors, migrating subjects, non-cooperating subjects). In 1989 for the first time in the CR stagnation of the incidence of bacteriologically confirmed TB of the respiratory organs was recorded. The number of patients (5.7/100,000) with TB with a microscopically positive bacteriological finding in sputum was also the same. A slowing down of the hitherto recorded favourable trend of TB must be foreseen. It will be important to maintain the contemporary system of TB surveillance.
