Abstract
ACUTE respiratory diseases are the commonest illnesses in the United States, outranking the next closest contender by five times. They are probably responsible for more absenteeism from school, industry and military duty than any other illness, imposing a tremendous financial burden. They stand fourth as a cause of days disabled. Yet knowledge of their etiology, prevention and treatment is meager indeed.The investigation reported in this paper deals with this problem in university students. As a well defined and closely followed group, students offer an opportunity for relatively long-term observation and careful study. Medical care in this university is provided . . .
