The guiding interest of this monograph has been epidemiological, not clinical, and operational rather than theoretical. The study was undertaken primarily to determine the effectiveness of the x-ray screening of recruits at induction and discharge in the detection of disabling tuberculosis in World War II. From 1942 to 1945, about 17,500 men were admitted to Army hospitals with a diagnosis of tuberculosis and ultimately separated for disability with an estimated cost of about 175 million dollars. About half the men rejected for tuberculosis had active, and half potentially active or inactive, lesions; 3,099 men discharged for tuberculosis (1943 to 1946) were studied with a control group of 3,000 enlisted men not discharged for tuberculosis. It is possible to operate an induction screen at different levels, depending on manpower needs. Substantial improvement in the screening appears to rest on supplementing the x-ray with such aids as the tuberculin skin test, which
