title: [Determination of the frequency of residual tuberculous changes in the lungs and the level of contamination in urban and rural populations].
abstract: The frequency of metatuberculous lesions and contamination levels were compared in 5341 urban and 5023 rural residents. It was shown that the frequency of residual tuberculous lesions in the urban (2.6 per cent) and rural (2.3 per cent) residents was the same while the frequency of posttuberculous lesions in the respiratory organs of the fluoropositive persons from the rural areas (65.3 per cent) was higher than that of the persons from the urban areas (43.7 per cent). Among the persons with x-ray signs of cured tuberculosis, positive reactions to tuberculin tests in 89.8 per cent of the urban residents and in 91.0 per cent of the rural residents were recorded. The frequency of the positive reactions to tuberculin corresponded to an increase in the number of the x-ray positive persons. The maximum increase was observed in persons at the age of 40 to 49 years.
