Abstract

Pochun-Goon is located in the north-eastern part of Kyunggi-Do and borders on Kapyung-Goon on the east with Yunchun-Goon and Kwngwon-Do on the north, with Yangjoo-Goon, Kyunggi-Do on the west and wouth. Pochun-Goon is mountainous and contains twelve myuns, So-I-Myun, Kasan-Myun, Koonnae-Myun, Changsoo-Myun, Shinbook-Myun, Ildong-Myun, Pochun-Myun, Chungsan-Myun, Naechon-Myun. Each Myus has about 10,000 population and has 5 to 7 Ris.
This survey was directed to this Goon as a part of the program of studying directly making a trip to each 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 many public health problem.
Among twelve Myuns, eleven Myuns were surveyed. One primary school from each myun was selected for this survey being asked about their custom of eating raw and inadequately cooked craysifh and crabs and their environmental situation regarding drinking water, and testing them with paragonimus antigen. The crayfish caught from these Myuns were examined for Paragonimus metacercaria.
The children ate raw crayfish were ranged from 3.6% in pochun-Myun to 16.0% in Naechon-Myun and male children ate maor raw caryfish than the female, the children who ate poorly cooked crayfish were ranged from 56.6% in Yungbook-Myun to 96.9% in So-I-Myun, crabs are rare in this Goon except for Pochun-Myun and Yungbook-Myun in which the children who ate soysouce soaked crabs 34.5% and 17.0% respectively. Such eating habits among children in this Goon are suggestive of a large infestation and of a continuation of paragonimiasis from early childhood. In environmental situations, those who drink the water of streams and from shallow wells have possibility of acquiring paragonimus metacercaria from the water were ranged from 4.3% in Pochun-Myun to35.2% in Koonnae-Myun
The positive rate with paragonimus skin tests show about 3% in Koonnae-Myun, ranging 5-10% in Ildong_Myung, Chungsan-Myun, Yungbook-Myun, 15.6%-33.9% in So-I-Myun, Kasan-Myun, Chang-Soo-Myun, and Yungjoong-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 enormous numbers. Crabs are rather rare in this Goon. The infestation rate of crayfish with Paragonimus metacercaria was found to be as follows: 0.6% in Kasna-Myun, 1.4%in Changsoo-Myun, 1.3% in Chungsan-Myun, and 2.2% in Yungjoong-Myun Metacercaria from the crayfish in other myuns was not demonstrated.
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. I wish the public health authorities and the school authorities in this Goon would strive to eradicate this bad custom.
