International measures against tropical diseases.

Abstract

The participation of the United States in international health programs not only serves the interests of both this country and all countries of the free world 1 but has brought rewards in many fields. International health activities vitally affect the health and strength of our economy. Present United States investments abroad, direct and indirect, private and governmental, have reached the vast total of 40 billion dollars 2 and are continuing to expand at a rapid pace. This expansion includes investments in tropical and semitropical areas. In the short period from the end of 1949 to the end of 1952, United States business firms increased their direct investment in Africa and Asia by over 65% and in Latin America by almost 25%. 3 An increase in the number of Americans employed abroad in civilian jobs can be expected to accompany this increase in investments. Trade with other countries is likewise growing.
