Status of Enterobius vermicularis Iifection in primary school children, Yongyang-Kun, Kyongbuk Province
Sŏn Hŏ and Chan Byong Park
Yongyang-gun Health Center, Kyongbuk 660-40, Korea.

An epidemiological study was undertaken to estimate the prevalence of Enterobius vermicularis infection among the primary (and infant) school children in Yongyang-gun, Kyongsangbuk-do. During the period from 2 to 14 December 1983, a total of 2,227 school children in 13 schools were examined one time by means of scotch-tape anal swab technique with a simple questionaire study on perianal itching, enuresis and school record.

The results are as follows:

1. The overall egg positive rate was 64.1 percent and the rate ranged from 46.6 to 86.7 percent by schools.

2. The egg positive rates of boys and girls were 60.5 and 68.0 percent respectively and the difference was statistically significant (p<0.005).

3. There was noted a tendency of decrease in prevalence by increase of the age of children.

4. It was revealed that perianal itching and school record were significantly correlated with E. vermicularis infection (p<0.05) while not in case of enuresis (p>0. l).
