Status of Enterobius vermicularis infection in preschool children in rural areas of Ningxia during 2015-2016

Abstract

Abstract:

To investigate the status of Enterobius vermicularis infection in preschool children in rural areas in Ningxia, 48 villages were selected in 13 counties （cities） as spots using the stratified cluster sampling method. A transparent adhesive tape test was performed in 3-6 years children to examine the eggs of Enterobius vermicularis. Results showed an overall prevalence of 1.3%（12/911）. The infections were detected only in Jingyuan, Longde and Pingluo counties, with prevalence of 14.3% （5/35）, 4.6% （5/110） and 3.0% （2/67）, respectively （P < 0.05）. There was no significant difference in prevalence between boys （1.7%, 8/472） and girls （0.9%, 4/439）（P > 0.05）, or between Han （1.4%, 7/499） and Hui （1.2%, 5/412） ethnicities （P > 0.05）. The prevalence showed a trend of decrease with age （P < 0.05）, being highest among 3-year-old children （2.9%, 4/173）. The results suggest a clear regional bias of prevalence among preschool children in rural areas of Ningxia. Efforts should be made to take measures specifically in these areas.
