HEALTH SURVEY IN PACIFIC U. 3. ARMED FORCES MEDICAL JOURNAL Table 15. Table 14. Percentage of chest x-rays indicative of active Diagnoses of tuberculosis for natives not x-rayed pulmonary tuberculosis by rank order on selected islands or atolls, Saipan, Palau, and Marshall Is- Tuberculosis lands districts atolls, Ine, Tabal, Lamotrek, Sonsorol, Elato, and Faraulep, over 3 percent of the x-rayed population had active pulmonary tuberculosis. An interesting experience was reported from Tabal Island. The U.S.S. Whidbey visited this island in November 1948 but, because heavy seas rendered the x-ray machine inoperable, the ship was forced to return at a later date to complete the examinations. During the initial visit one 39-year-old womanonthe island showed clinica] evidence of pulmonary tuberculosis and had positive sputum for tubercle bacilli, At that time nine people were living in the same house with this active case of pulmonary tuberculosis. Eighteen months later when the survey ship returned the woman had died of tuberculosis. The chest roentgenograms for the other nine members of the household were still negative for tuberculosis. Table 15 shows the diagnoses of tuberculosis that occurred among inhabitants who were not x-rayed. These diagnoses had been established prior to the health survey and, in some cases, the individuals were receiving treatment forthe disease. Nearly 90 percentof the population were tuberculin-tested. Table 16 shows the distribution of islands by percentof positive tuberculin VOLUME 10, NO. 10 oD ae | tests. Two test-strength dosages of tuberculin, 0.0001 mg PPD and 0.00002 mg PPD, were used for thetests, the latter dosage being used early in the program andoccasionally when the 0.0001 mg PPD dosage was not available. On most of the islands in the Marshall Islands district the 0.0001 mg PPD dosage was used, while primarily the 0.00002 mg dosage was used in the Palau district. Both dosages were used in the Saipandistrict. From Babelthuap Island, where the 0.0001 mg PPD tuberculin dosage was used on about one half of the “tested population and the 0.00002 mg PPD tuberculin dosage was *Palau district. **Marshall Islands district. ***Saipan district. 1214 Other ad 0 ' Utirik Atoi** . ‘ 12 1.2 ee Arno Jsland** Rota Island*** Kwajalein Atoll Majuro Atoll Tabal Island bee 0 & Uilithi Atoll* Ailuk Atoll bof 1.3 Sonsorol Island Yap Islands Marshall Islands em Woleai Atoll* Male Bronchus| genitalia bP .3 1 0 0 0 0 a 0 0 0 10 3 Namorik Island** Kwajalein Atoll** Angaur Isiand* Eauripik Atoll* Lib Island** Likiep Atoll** Merir Island* Peleliu Isiand* Pulo Anna Island* Tobi Island* wo Ailuk Atoll** 2.8 2.8 24 2.4 2.2 2.1 2.1 18 17 1.6 Saipan: Saipan Island Palau Babelthuap Island Fais Island KororIsland Negulu Atoll Peleliu Island Satawal Island | 2.9 Fais Istand* Yap Islands* Aur Island** Koror Island* Maloelap Atoll** Kayangel Atoll* Negulu Atoll* Tinian Island*** Hfalik Atoll* Saipan Island*** Lymph nodes ‘ wo Mili Atoli** Skin Arrested 1 1,2 9 7 6 Ai a4 Active I 6.8 3.8 3.6 3.5 3.4 3.1 ’” Pulmonary ao Faraulep Atoli* Elato Atoll* Sonsorol Island* Lamotrek Atoil* Tabal Island** Ine Island** cases t Wotie Atoll** Majuro Atoll** Mejit Island** Babelthuap Isiand* Satawal Island* Ebon Atoll** Total Percent active oe RO Island or atoll and district om q Percent active Peenvma Ge & we he Pp Island or atoll and district Table 16.
