There is evidence that man has suffered from tuberculosis for more than 5,000 years, and through crowded living conditions, debilitation, and malnutrition, tuberculosis became epidemic in Western civilization and was a major cause of mortality. Identification of the tubercle bacillus as the causative agent in 1882 firmly established the infectious nature of the disease and the development of sanatoriums soon followed. ⋯ Despite these effective chemotherapeutic and preventive agents, tuberculosis has receded to socioeconomically disadvantaged urban and rural areas, where the incidence parallels that of developing countries. Conquest of the disease will require improved health care delivery to the indigent and dispossessed.
