the indigenous population.’ The ship reported that, in general, the health of the Micronesians was “excellent” and nutrition and sanitation were “good.” The specific conditions discovered or verified by the survey were proof, however, that the control and elimination of disease was a long range problem. The WHIDBEY statistics * showed that the most prevalent, widespread diseases were tuberculosis, intestinal parasitism, and yaws. Leprosy was of major importance throughout the area, filariasis and encephalitis were found in small incidence in the Carolines, mental disease occurred in only five individuals, venereal disease was practically nonexistent, and malaria was completely absent. Some measles and meningitis were found among children. Dengue and typhoid fever, which had previously been thought to be widspread, did not appear in any area. Among the miscellaneous diseases, the most preva- lent were diseases of the skin, eyes, and respiratory organs: of wide prevalence were degenerative joint diseases. inflammatory diseases of the ear, neoplastic diseases, rickets and vitamin deficiency, and anemia. Tuberculosis was out of control and was the most serious health problem. Its high incidence on Saipan, where in 1947 and rgq48 the deaths resulting from it exceeded the numberof deaths fromall other causes, had been recognized for some time. but the WHIDBEYsurvey produced alarming statistics from all other areas. Chest defects accurred in 4.5 percent of persons examined in the Saipan, Palau and Marshall Islands Districts. Incidence of pulmonary tuberculosis in the various districts was: Saipan, 2 percent; Palau, 1.6 percent; Truk. 9.92 percent; Ponape, 1.7 percent; Marshalls, 0.8 percent. Incidence on individualislands varied from Kwajalein’s 0.1 percent to Faraulep’s 6.8 percent; Saipan had 3.9 percent; Yap had 4.9 percent. Reaction to tuberculin tests was exceptionally high: of the approximately go percent of the population tested in the Saipan, Palau and Marshall Islands Districts, 46.5 percent had positive reactions: incidence for individual islands varied from 6.7 percent for Elato to 84.5 percent for Yap.
