Abstract

This study was undertaken to evaluate the status of human paragonimiasis in Kang Hwa Gun, Kyunggi Do, Korea from March 1973 to October 1975 by the use of intradermal screening test with Veronal buffered saline antigen. A total number of 7,352 (male 3,936; female 3,4l6) consisting of 3,447 primary school children, 2,689 middle school students, l,008 high school students of 9 Myuns out of 13 Myuns of this County and 208 residents of all age group in Kilgeong-Ri, Yangdo Myun were examined by the intradermal test with Paragonimus antigen. In order to detect Paragonimus egg, the sputum and the stool examinations were undertaken on the residents in Kilgeong-Ri.The infestation rate of crayfish with Paragonimus metacercaria was also examined in Konneung and Jeongha village in Kilgeong-Ri.

The following results were obtained in this survey:

1. As a whole, 16.6 per cent of the examiners showed positive reaction with sexual difference of 16.1% in male and 14.8% in female.

2. In age groups, the highest positive rate showed in middle school age group (17.1%) than primary school (14.0%) and high school age group (11.4%).

3. In regional differences of positive rates, the highest rate (28.4%) showed at Yangdo Myun followed by Kilsang Myun (27.0%), Hwado Myun (%), and Naega Myun(20.8%).

4. In the result of 208 residents Kilgeong-Ri, the positive of 36.1% in male and 20.2% in female. The highest positive rate showed in 10 to 19 age group (41.5%).

5. Among the residents in Kilgeong-Ri, Paragonimus eggs were detected in 11 residents by the sputum and the stool examinations.

6. The infestation rate of crayfsh with Paragonimus metacercariae was 100% (41 out of 41 crayfishes) in Konneung village, and 84.6% (9 out of 13 crayfishes) in Jeongha village, Kilgeong-Ri.

7. The fluctuation of the infection rate of crayfish with Paragonimus metacercariae was decreased in Konneung village in 2 years after the treatment with Bilevon against 10 paragonimiasis patients.
