[Tuberculosis morbidity in regions with a low population density].

Tuberculosis incidence was studied in the northern areas of Irkutsk Province with low population density. In the areas slower lowering of pulmonary tuberculosis incidence was noted. The main contingent of the new cases included persons with the disease detected during fluorographic examinations. In the areas with low population density, the percentage of the new cases with tubercle bacilli isolation and late diagnosis of tuberculosis was higher than in the areas with high population density. The influence of migration on the epidemiological status with respect to tuberculosis in the areas with low population density was less significant as compared to that in the areas with high population density.
