[Aspects of tuberculosis prevention in the industrial environment].

The dynamics were studied of the tuberculous endemy in a limited area of the Cluj-Napoca District over a period of 5--16 years. An industrial environment was considered in comparison with a non-industrial one in the vicinity. The results show a marked decrease in the incidence of tuberculosis in the industrial environment (from 710 0/0000 in 1961 to 102 3/0000 in 1976), but, at the same time, it was demonstrated that morbidity due to tuberculosis is higher as compared with the non-industrial area (318 0/0000 as compared with 49 0/0000). The importance is discussed, of some particular factors of the industrial environment, such as pneumoconioses -- of which the most important are those due to silica -- which are significant risk factors for tuberculosis. A close cooperation is recommended, between enterprise physicians and pneumophtysiologists working in territorial polyclinics.
