Prevalence of tuberculosis was investigated on 23, 217 inhabitants of Okierabu-island in October 1961, employing tuberculin testing, chest X-ray examination and the bacteriological examination of laryngeal swab in the cases having abnormal findings in X-ray films. This island is located in the southern part of Tokunoshima island, where the tuberculosis mass survey was done in 1960. The results obtained were as follows: 1) The number of females was greater than that of males. The population in the age-group of 1629 years old was markedly less than that of the average figures in Japan. 2) The rate of re sponse was 98.6 % to the total inhabitants. The majority of the unexamined people was in travel outside of this island. 3) The positive rate of tuberculin reaction was 59.0 % which was higher than that of Tokunoshima Town. The positive rate of tuberculin reaction by sex and age group were almost similar to the figures obtained in Tokunoshima Town. Annual rate of positive conversion of tuberculin reaction due to natural infection was estimated at 1.2 % on the average. 4) Tuberculin reaction was tested employing PPD-s in a concentration of O.05 mcg per 0.1 ml. Among positive reactors, reactions with double erythema were found in 38.9 % and strong reactions with vesicle, necrosis or lymphangitis etc. were found in 5.9 %. 5) The nu mber of persons showing tuberculous changes on chest films was 2, 765, i. e.12.3 % to all examinees, 12.0 % in male and 12.5 % in female. Total number of morbid (active and inactive tuberculosis) cases was 725 (3.2 %), 3.9 % in male and 2.6 % in female. And the active cases indicated medical treatments were 514 (2.3 %), 2.8 %in male and 1.8% in female. These figures were higher than those of Tokunosima Town, but lower than the average fiegures of Japan. The rate of cavitary cases was 0.4 % to the total examinees, which was similar to the average of Japan and a little higher than that of Tokunoshima Town. 6) Okierabu-island was divided into two towns, Wadomari and China. In China Town, the positive rate of tuberculin reaction, the rate of strong reaction among positive reactors as well as the prevalence of cavitary tuberculosis cases were higher than those in Wadomari Town, and this can be explained by the fact that the tuberculosis control programme has been conducted more intensively in the latter than in the former.
