The prevalence of enterobiasis in children attending mobile health clinic of Huachiew Chalermprakiet University.

ABSTRACT

A cross sectional survey of Enterobius vermicularis was carried out in 808 children in the Bangkok metropolis and nearby provinces. This was accomplished in a mobile health clinic from Huachiew Chalermprakiet University provided for communities in the areas during April 1999 to May 2000. Children 5-10 years of age were investigated for infestation of Enterobius vermicularis. Diagnosis was done by means of the transparent tape swab technique to recover eggs in the perianal region for examination under a light microscope. The average infection rate in children was 21.91%. The highest infection rate (38.59%) was found in Ang Thong Province, while the lowest one (11.66%) was found in Chonburi Province. The rate of infection seemed to relate to household environmental factors. The infection rate was significantly higher (p<0.05) in agricultural areas and areas farthest from urban Bangkok. Industrial and urban areas had the lower rates of infection. There was no significant difference (p>0.05) in the incidence of infection between males and females.
