Clonorchiasis sinensis is one of the most important endemic diseases in Korea, and this disease has been known to be one of public health concern in many areas of Korea. This survey was undertaken to evaluate the status of clonorchiasis in Yeoju Gun, Gyeong-gi Do from July to September 1980.
A total of 1,194 male students were examined by intradermal test with Clonorchis .antigen.
In order to detect Clonorchis egg, the stool examinations were undertaken to1, 158 students, and the intensity of the Clonorchis infection was estimated by the Stoll´s egg count.
The prevalence rate was reanalyzed by the regional groups for an investigation of regional characteristics of infection.
The following results were obtained-in this survey.
1) Among 1,194 students in Yeoju Eup, positive rate of intradermal test with C. sinensis antigen was 17.2 per cent. (middle school 14.6 and high school 20.1% )
2) In the examination of 1, 158 stool specimens, Clonorchis eggs were found in 97 ( 8.4%) cases.
3) Mean E. P. G. of-Clonorchis infected case was 1,330±2,620.
4) The degree of the intensity of Clonorchis infection by E. P. G. count was distributed as 73.6% in light infection (100 - 999), 22.6 % in moderate infection (1,000 - 9,999), and 3.8% in heavy infection (10,000 - 29,999)
5) High prevalence rate of Clonorc his sinensis was found in the Sang -Ri (9.3%) and Ha- Ri (8.4%) in Yeoju Eup. Neighbouring Bugnae Myun (11.5%), Gangcheon Myun(12.1%) and Neungseo Myun (11.1%) adjacent to the river had a similary high prevalence of C. sinensis.
