A program for the early detection of pulmonary tuberculosis among students of nursing was instituted at the Philadelphia General Hospital in 1935. The present report deals chiefly with information which was obtained concerning the epidemiology of tuberculosis among students of nursing in a large general hospital.
The intracutaneous tuberculin test and roentgen examination were given to each student on admission to the training school. The students who failed to react to tuberculin on admission were retested every four months until a positive reaction was observed. Fluoroscopic examination of all positive reactors was made at four month intervals and roentgen examination was made if a lesion was suspected or demonstrated by use of the fluoroscope. In recent years it has proved more satisfactory to examine all students by means of the fluoroscope because the number whose reactions remained negative to tuberculin was small. In addition, film examination was made whenever respiratory
