Seroepidemiological Survey on Echinococcosis among Children in Ningxia Hui Autonomous Region in 2012

Abstract

Abstract:

【Abstract】 According to the population structure， a stratified cluster sampling was carried out in 22 counties/cities/disticts of Ningxia Hui Autonomous Region from June to August 2012. Serum anti-echinococcus IgG was detected by ELISA. Among 22 995 sampled children from 91 primary schools， the sero-positive rate was 2.9%. The rate in males and females was 2.8% (333/11 840) and 3.0% (337/11 155), respectively (χ2=0.88, P>0.05). Higher serum positive rate occurred in Yuanzhou District (10.6%, 169/1 602), Yanchi County (9.1%, 74/810), and Zhongning County (7.1%, 96/1 350) (χ2=1826.51, P﹤0.05). The rate in rural schools (3.1%, 371/11 963) was higher than that of urban ones (2.7%, 368/13 834) (χ2=4.30, P﹤0.05), and higher in Hui nationality(3.3%, 302/9 127) than that of Han nationality (2.7%, 368/13 834) (χ2=8.17, P﹤0.05). The highest positive rate was found in the group of 7 to 9 years (3.2%, 180/5 662) and of 12 years (3.3%, 254/7 694) (χ2=4.11, P﹤0.05).
