In the summer of 1960 a girl with cerebral paragonimiasis was admitted to the psychiatric service of Chikushi National Hospital from Kami-agata Country (Tsushima Island), Nagasaki Prefecture and she died shortly after hospitalization. Her parents also were suffering from paragonimiasis, and had no knowledge about the disease, Since this incident, we have carried out epidemiologic studies for four years, and some campaign of education regarding paragonimiasis in Tsushima, Namely, parasitologic studies on the crabs, or the skin test, and explanations concerning life cycle of paragonimus using many slides for the inhabitants at various places have been done. In addition to these, since 1961 in every year 2, 000 copies of the pamphlet for education have been distributed to the people in Tsushima. On the other hand through the newspapers, radio and television the importance of prophylactic measure has been emphasized to the inhabitants, According to our studies, parasitic rates of metacelcaria in the Nita River (especially 24.3% in Kurusu), 42.5% in the Mine River, 59.8% in the Kusu River, 58.1% in the Are River, and 80.0% in the Azamo River, which appeared to be high positive rates.High positive results of the skin test obtained from school boys and girls using the VBS antigen were 22.7% in Sago area, 37.6% in Hamagusu, 21.9% in Are, and 23.8% in Naiin. High positive skin test corresponds with high parasitic rate of metacelcaria in the crabs in these districts, In the skin test for 1816 individuals among the inhabitants in Sago, Nita, Mine and Are areas, where appeared to show high infectious rate, the positive rate was 22.6%. In 1962, the questionnaire was sent to every home in order to know the inhabitants' response to our campaign of education and some following interesting data were obtained.The spread rate of knowledge about the disease among the inhabitants are showing remarkable increase, namely 33%, 34% in 1960, 1961, and 1962, respectively.As to the processes obtained the knowledge, 35 per cent of the people owed to the activities of our group, 34% from the talk of folks with this matter, and 2096 from information by the newspapers, radio and television.In Tsushima, the most families (93 per cent) have tasted the crabs and in 1960 48.2% of the inhabitants ate the crabs. Year by year, however, the eating ratio of crabs was decreasing, i. e., it was 21.9% in 1961, and in 1962 it dropped to only 2.9%. As to the cooking ways of crabs, 66% of people took Miso soup containing grinded crabs, but no one showed such habit as eating the raw crabs.Since 1960 111 carriers of paragonimus eggs have been found, among them 74 instances by us, 35 cases by the Institute of Endemic Diseases, Nagasaki University, and 9 by doctors in Tsushima. In 1963, under cooperation with the National Tsushima Hospital, group treatment for paragonimiasis cases with Bitin was made and 50 volunteer cases have completed the treatment.
