To evaluate the parasitic infection rates among inhabitants in urban area of Seoul, Korea, a total of 5,275 stool and anal swab specimens was obtained from 2,527 male and 2,748 female living in 24 Dongs of 17 Kus. Cases were sampled randomly to represent 1,000 inhabitants referred to the census in 1980. The methods employed were formalin ether technique to detect helminthes ova and protozoan cysts and scotch tape anal swab technique to detect eggs of Enterobius vermicularis.
The results obtained are as follows ;
1) Total positive rate of helminthes was 23.5% among 5,275 (male 22.5% and female 24.5%) specimens. Nine kinds of the helminthes were detected and infection rates of each helminth were ; Ascaris lumbricoides 4.1 % , Hookworm 0.1%, Trichuris trichiura 11.1%, Trichostrongylus orientalis 0.1%, Clonorchis sinensis 1.2%, Metagonimus yokogawai 0.1%, Taenia spp. 0.2%, Hymenolepis nana 0.3 %, and Enterobius vermicularis 9.6%.
2) Total positive rate of intestinal protozoa was 1.4%. Four kinds of the protozoan cysts were detected and the infection rates of each protozoa were; Entamoeba histolytica 0.15%, E. coli 0.4%, Endolimax nana 0.04% and Giardia lamblia 0.89%.
3) No significant differences in the parasitic infection rate by sex was noticed although male group showed lower infection rate than female group. However the incidence of C. sinensis, M yokogawai and Taenia spp. was twice as much in female group as in male group.
4) No difference in the infection rate by age was found although E. vermicularis positive rate was highest in "0~9 years group " by 2.1% and C. sinensis infection rate was higher in over ´30~39 years group ".
The parasitic infection rate of the present study was significantly lower than those of previous reports in Seoul area and other provinces.
