目的 了解江西省2016-2019年农村地区儿童蛲虫感染情况及变化趋势,为全省制订防治对策提供科学依据。方法 2016-2019年在江西省83个县（市、区）设立土源性线虫监测点,对各监测点3~9岁儿童采集粪样,用改良加藤厚涂片法（一粪二检）和胶带纸肛拭法检查蛲虫感染情况。采用SPSS 25.0统计软件对数据进行统计描述、比较和趋势分析。结果 2016-2019年共检测儿童32 587人,蛲虫感染率分别为10.2%（931/9 155）、12.8%（1 045/8 145）、13.1%（964/7 343）和10.5%（836/7 944）,呈先升后降趋势（P > 0.05）。新余、九江、赣州和抚州等4个市连续4年儿童蛲虫感染率均≥ 10%,其中新余4年均最高,感染率分别为17.4%（8/46）、24.0%（6/25）、32.3%（10/31）与22.2%（12/54）。男童与女童感染率接近,2016-2019年分别为10.1%（506/4 989）和10.2%（425/4 166）、13.0%（568/4 383）和12.7%（477/3 762）、13.3%（530/3 981）和12.9%（434/3 362）、10.3%（440/4 283）和10.8%（396/3 661）（P > 0.05）。除2016年散居儿童感染率最高为13.7%（83/606）外,其余年份感染率最高均为幼托儿童,感染率分别为13.8%（512/3 705）、16.3%（567/3 486）和12.3%（477/3 885）。4~7岁儿童感染率较高,且各年度感染率均≥ 10%。胶带纸肛拭法蛲虫感染检出率为11.4%（3 730/32 587）,高于改良加藤厚涂片法的1.2%（392/32 587）（P < 0.05）。结论 江西省2016-2019年儿童蛲虫感染率较高,4年间感染率的变化不明显,应加强对幼托儿童蛲虫感染的监测与精准防治。

Objective To understand the status and the changing trend of Enterobius vermicularis infection in children in Jiangxi Province during 2016-2019, and to provide scientific basis for formulating control strategies in the province. Methods Surveillance sites of soil-transmitted helminth (STH) were set up in 83 counties (cities and districts) in Jiangxi Province during 2016-2019. Children aged 3-9 years were examined for Enterobius vermicularis infection by the modified Kato-Katz thick smearmethod (two slide reading/one fecal sample) and the adhesive cellophane anal swab method. The SPSS 25.0 statistical software was used to perform statistical description, comparison and trend analysis on the data. Results A total of 32 587 children were examined in 2016-2019, revealing a prevalence of E. vermicularis infection of 10.2% (931/9 155), 12.8% (1 045/8 145), 13.1% (964/7 343) and 10.5% (836/7 944), respectively, in each year, showing a trend of first increase and then decrease (P > 0.05). The average infection rate in children remained ≥ 10% in 4 consecutive years in Xinyu, Jiujiang, Ganzhou and Fuzhou Cities, among them the Xinyu City had the highest infection in each year: 17.4% (8/46), 24.0% (6/25), 32.3% (10/31) and 22.2% (12/54), respectively. The infection rate was comparable between males and females [10.1% (506/4 989) and 10.2% (425/4 166) in 2016, 13.0% (568/4 383) and 12.7% (477/3 762) in 2017, 13.3% (530/3 981) and 12.9% (434/3 362) in 2018, 10.3% (440/4 283) and 10.8% (396/3 661) in 2019, respectively; P > 0.05]. The infection rate among nonboarding children was highest (13.7%, 83/606), whereas in all other years, the kindergarten children had the highest infection rate [13.8% (512/3 705), 16.3% (567/3 486) and 12.3% (477/3 885), respectively]. The infection rate was relatively higher in children aged 4-7, which remained≥ 10% in all years. The detection rate using adhesive cellophane anal swab method was 11.4% (3 730/32 587), significantly higher than the 1.2% (392/32 587) using Kato-Katz thick smear method. Conclusion A higher prevalence of E. vermicularis infection was found among children in Jiangxi Province in 2016-2019, with no significant difference between years. It is necessary to strengthen surveillance and appropriate control for kindergarten children.
