Egg detection rates of Enterobius vermicularis in children

ABSTRACT

The cello-tape anal swab specimens from 936 primary school children in Seoul, 308 primary school children in a rural area and 92 children in Nanjido, were examined for Enterobius vermicularis eggs. Out of 936 specimens from a primary school in Seoul, E. vermicularis eggs were detected in 114 specimens, the egg detection rate being 12.2 percent. In 308 specimens from a primary school in a rural area, 77 (25.0 percent) were positive for E. vermicularis eggs. Among 92 specimens from Nanjido children in Seoul, egg positive rate of E. vermicularis was 28.3 percent. The egg detection rate of primary school children in Seoul was significantly lower than that of primary school children in a rural area and of Nanjido children. The egg detection rate in boys was lower than that of girls. As the age of children increased, the egg detection rate decreased.
