Kapyung-Goon is located in the north-eastern part of Kyunggi-Do and borders on Kangwon-Do on the east, with Pochun-Goon, Kyunggi-Do on the northwest, with Yangjoo-Goon, Kyunggi-Do on the southwest and with Yangpyung-Goon, Kyunggi-Do on the south. Kapyung-Goon is mountainous and contains Sang-Myun. Ha-Myun. Kapyung-Myun, Book Myon, Woisuh-Myun, Nam-Myun, and Sulak Myun Each Myun has about 10,000 population andhas 5 to 7 Ris.
This survey was directed to this Goon as a partof the program of studying directly making a trip to eack Myun in every Goon in Kyunggi-Do as finding out the districts which have the poisonous crayfish and crabs having Paragonimus metacercaria is urgent because many children in rural areas eat raw and slightly roasted crayfish and crabs and there is a traditional custom in Korea of taking raw crayfish juice for the treatment of measles, producing manny Public health Problem.
Among seven Myuns in Kapyung-Goon, twoMyuns, Woisuh-Myun and Nam-Myun. are excludedbecause they are located along the North Han Riverand are considerrd to be not so infested by the Pa64 (J46) ragonimus westermani. One primary school front each Myun in the other five Myuns, Sang-Myun,Ha-Myun, Kapyung-Myun, Sulak-Myun and Book-Myun, was selected and the pupils in older agegroups were tested for this survey being asked about their custom of eating raw and Inadequately cooked crayfish and crabs and their erlvironmental situation regarding drinking water, and testing them with Paragonimus antigen. The crayfish caught from these Myuns were examined for Paragonimusme tacercaria.
The children ate raw crayfish were 8.8% in Sang-Myun,5.2% in Ha-Myun, 5.8% in Kapyung-Myun,the children who ate poorly cooked crayfish were90.1% in Sang-Myun. 87 0% in Ha-Myun, 59.4%in Kapyung-Myun, 57 9%; in Sulak-Myun add 69.7% in Book-Myun, the children who ate soysoucesoaked crabs and slightly roasted crabs count 35.1% and 40.3% in Ha-Myun respectilvly. Such eating habits among children in this Goon are suggestive of a large infestation and of a continuation of paragonimiasis from early childhood. In enrironmental situations, those who drink the water ofstreams and from shallow wells have possibility of acquiring Paragonimus metacercaria from the water directly. Those children who drink such water count30.8% in Sang-Myun, 29.9% in Ha-Myun, 17.8%in Kapyung-Myun, 28.5% in Sulak-Myun and 20.3% in Book-Myun.
The positive rate with Paragonimus skin tests show higher percentages as 13.2% in Sang-Myun, 28.6%in Ha-Myun, 47.8% in Kapyung-Myun, 29.5% in Sulak-Myun and 24.2% in Book-Myun in the low age group. This survey shows paragonimiasis in this Goon is uniformly distributed in every Ri ineach Myun.
This Goon is very mountainous and in the many valleys in the deep mountains. the first intermediate host, snails the second intermediate host, crayfish,propagate actively and are produced in enormousnumbers. Crabs are rather rare in this Goon. Theinfestation rate of crayfish with Paragonimusmetacercaria was found to be as follows : 1.1% inSang-Myun, 3.O% in Ha-Myun, 2.7% in Kapyung-Myun, 47.0% in Sulak-Hyun and 5.6% in Book-Myun respectively.
The custom of taking raw crayfish juice for the treatment of measles is also prevalent in this Goon which may give many harmful effects to growing children. 1 wish the public health authorities and the school authorities in this Goon would strive to eradicate this bad custom .
