In Brazil, tuberculosis is one of the major communicable diseases. It is found in every Brazilian state, including those in the most developed regions with more financial resources and better health care. According to ’ an estimate made in 1965, there were then 400,000 active cases of the disease in Brazil (41. In 1979, the approximate incidence of tuberculosis in Brazil, according to reports of new cases being treated, was at a level of 5 cases per 1,000 inhabitants, amounting to some 57,000 new cases per year. In fact, however, the actual incidence appears to be somewhat higher-on the order of 100,000 new cases per year. Considering the average duration and lethality of the disease, it therefore appears that there are presently some 300,000 cases of tuberculosis in Brazil (2). Despite our knowledge of the disease’s etiology, therapeutic research, and diagnostic and treatment facilities, tuberculosis still poses a difficult public health problem because of
