One of the helminthologic features of World War II was the exposure of servicemen to infection with hookworm in areas infested with Ancylostoma duodenale, particularly in the Pacific islands. Reports of studies confirming this are gradually accumulating. The information available to date, together with certain emphases arising from a further examination of data secured by us on navy and marine personnel while on Guam, are brought together here to determine their relation to the question of the potential establishment of A. duodenale in the United States.

REVIEW OF PREVIOUS REPORTS  That A. duodenale was endemic in many of the Pacific islands, its amount increasing in relation to Necator americanus as the mainland of Asia was approached, has been recognized for many years. There may, however, be considerably more A. duodenale in some areas than hitherto has been realized. The rate of infection with A. duodenale in troops who have been
