This paper is devoted to analyse the present condition of community health, as a case study, at Tonaki village, one of isolated islands belong to Okinawa prefecture. The population has been decreased since 1946 and is only 702 including many of the aged. Though the records to know the history of Tonaki island has been rarely found, it was presumed that the inhabitants had been led their lives by fishing. The way of life in Tonaki was differented from Okinawa mainlands. After the World War II, medical care for people has been carried out mainly by medical assistant (so called IKAIHO) and or public health nurse. As the other medical personnel, midwife, homehelper and school nurse lived and worked there each several years. Since 1974 a medical doctor has been there and has carried out medical activities. In this papers, at first, the health conditions of peoples were reported from the various aspects. Secondly, it was observed that how did they perceive about their health condition and acted when they broke their health. They had been disadvantage on medicine, because they had no medical doctor so often beside men had been abroad for many years for fishing in their history. Thirdly, the history of medical care at Tonaki island was observed through the life history of the old man from the view point of relation between the individual and the community.
This is a report of the development and results of a certain health method which was applied to the patients, 2 males and 2 females, diagnosed as "gallergic coryza". They stayed at the Health Recovery and Promoting Center at Yao from April 1, 1972, to the end of March, 1975, and practised the health-recovery-and promoting method of fasting, eating only unpolished rice and vegetable foods, and having a cold-and-hot-bath taken one minute alternatively, and so on. All four patients gradually began to take a turn for the better in such symptoms as nasal obstruction, Nasal discharges, sneeze and headache. That is, within 1 or 2 months after their accommodation, above symptoms of them were extinguished or remarkably improved.
From 1972 to 1974, HI antibody titer against rubella virus among the inhabitants was evaluated in Ishigaki, Iriomote, Kuroshima, Aragusuku and Yonaguni islands of Yaeyama archipelago, Okinawa Prefecture. The date of onset, size and other charateristics of the rubella epidemics in the past was retrospectively inferred by the date on the rates of the antibody positive individuals among each age groups of the islanders. The antibody positive infants were few im number, and the occurrence was sporadic in the communities throughout the archipelago. While the rate of the positive individuals was about 30 per cent among the younger school-children, it leaped to such a high level as 80 per cent or more in the older classes. This age of the leap was variable among the communities depending on their demographic, geological and social conditions, ranging 7 to 10 years of age. It is presumed that such a variance of leaping age in each communities reflects the course of the rubella epidemics which invaded Okinawa island in 1964 and then propagated southward to the Yaeyama archipelago.
