Since the start of the war it has been universally recognized that troops deployed in the tropical theaters of operation would be extensively exposed to a variety of diseases which either do not occur in the United States or are not widely prevalent. Much speculation has taken place as to the disease problems which might arise when the Army was demobilized and troops brought home and returned to civil life. From time to time representatives of the Army, Navy, and U. S. Public Health Service have consulted to determine precautions which should be enforced to prevent the introduction of exotic diseases. Since the time for demobilization of the forces which campaigned in the Pacific, Africa, the Middle East and the Orient has now arrived, it is appropriate to evaluate the extent to which various tropical diseases have been a problem among troops and to review the measures which have been adopted by the Army to prevent introduction of these diseases by men returning from overseas.
