A survey on helminthic infections in a rural area of Korea, Dongnae Area, Shindong Myon, Chunseong Gun, Kangwon-do (Province) was undertaken to evaluate the status of infection, providing the basic data for control of parasitic infection. The survey has been conducted from March to September, 1973 on the 3,454 inhabitants (47.2%) of 7,314 of the area. Cellophane thick smear technique was appled for stool examination.
The data were analysed and showed the following results:
1) The overall prevalence rate of helminthic infections by stool examination was 75.7% (male 73.7%, female 77.6%). The rate of each helminth was as follows: Ascaris lumbricoides 61.9%, Trichuris trichiura 41.9%, hookworm 1.0%, Trichostrongylus orientalis 0.5%, Enterobius vermicularis 0.3%, Clonorchis sinensis 0.2%, and Taenia species 0.8%.
2) The infection status of Ascaris lumbricoides by occupation of surveyed population revealed significant differences: professional occupation group 11.1%, workers in transport and communication occupation 33.3%, and farmers 50.2%.
3) The infection rate of Ascaris lumbricoides revealed significant difference by the educational background of over 25 years of age group: lower rate in the higher educational level.
4) The overall helminth prevalence rate was not significantly different between the group of the high and low socioeconomic classes.
5) The prevalence rate of Ascaris lumbricoides was significantly higher in agricultural households (65.2%) than in non-agricultural households (50.4%).
6) The familiar aggregation of Ascaris lumbricoides infection among 950 (199 households) population was analysed and revealed highly significant aggregation pattern. And this aggregation was more marked in agricultural households than in non-agricultural households.
