[Epidemiological hazardousness of patients with renal tuberculosis]

A total of 408 nephrotuberculosis patients detected in a large industrial city for the period of 1975-1989 and 645 subjects from their family and residence surroundings were subjected to a current and retrospective epidemiological examination to evaluate the epidemiological danger presented by the patients sick with active tuberculosis of the urinary organs. Washings collected from the various objects in 100 apartments of these patients were studied for M. tuberculosis in the genitourinary and pulmonary departments of a tuberculosis hospital. Nephrotuberculosis patients, including bacilli carriers, are only the potentially dangerous sources of tuberculosis infection. The volume of antiepidemiologic and preventive measures in the family--apartment foci formed by such patients should be lessened at the expense of reduction of disinfectant measures, the volume of chemoprophylaxis, public health service patronage and of the number of subjects from group IV of dispensary record.
