|
This study was undertaken to evaluate the present status of intestinal helminthes infection in rural areas of Korea from Dec. 1976 to Feb. 1979.
The 4,311 stool specimens collected from 4 mountainous areas, 2 plain areas and 4 river basins were examined.
The methods employed were Kato´s cellophane thick smear technique and brine Rotation technique.
The results are as follows:
1. The positive rate of intestinal helminth of any kind was 73.4%. It was 82.9% in river basins, 70.2% in plain areas and 70.4% in mountainous areas.
2. The positive rates of intestinal helminth
were; Ascaris lvmbricoides 42.5%, Trichocephalus trichiurus 51.4%, Hookworm 4.2°%, Clonorchis sinensis 4.0%, Metagonimus yokogawai 5.7%, Hyrnenolepis nana 1.3%, Taenia species 1.0%, and Trichostrongylus orientalis 1.2% respectively.
3. Sexual distribution of helminthic infections showed higher rate in female than that of male except C. sinensis; H. nana, Taenia species, and M. yokogawai.
4. Infection rates of T. trichiurus, Hookworm and C. sinensis increased with age, but conversely H. nana were more prominent in younger age.
5. No geographical difference was noticed except that, M. yokogawai (20.9%), C. sinensis (14.2%) in river basins and Taenia species (2.3%, by applying only s´ibl examination) in mountainous areas were higher than the other 2 areas.
