The paper deals with the results of analysis of the clinical types of pulmonary tuberculosis by the examination findings of new cases in 1990 (n = 1623), 1993 (n = 6686), 1994 (n = 7460), and 1995 (n = 9748). The analysis was made by the diagnoses established in patients identified in 12 areas of the Russian Federation. The proportion of clinical types of tuberculosis, the rate of detection of destructive changes in the lung and bacterial isolation were taken into account. Moreover, tuberculosis complications on detection, the dissemination of the process and concurrent diseases were borne in mind in patients with infiltrative tuberculosis. It was found that new cases of pulmonary tuberculosis increased, but the proportion of its clinical forms and patients with destructive changes in the lung and isolated strains remained unchanged in the past 3 years (1993-1995). The vast majority of new cases of tuberculosis (91.9-91.4%) includes patients with treatable diseases in whom a good clinical outcome can be expected.
