摘要:

目的 了解江西省信丰县人群华支睾吸虫感染情况,为制订防治策略提供依据。方法 在信丰县按地理方位划分东、南、西、北、中等5个片区,每个片区随机抽取1个乡镇的1个村,分别为古陂镇余村、大塘埠镇樟塘村、正平镇正坳村、西牛镇黄泥村和嘉定镇焦坑村作为人群华支睾吸虫感染情况的国家监测点。2016-2019年,每个行政村每年整群抽样3周岁以上常住居民,调查人数不少于200人。采集粪样用改良加藤厚涂片法(一粪二检)检测华支睾吸虫感染情况。在每村受检人群中随机抽查150人以上进行问卷调查,内容包括华支睾吸虫病防治知识、态度和行为。采用χ2检验比较组间率的差异。结果 2016-2019年信丰县国家监测点人群华支睾吸虫感染率分别为9.3%(96/1 027)、8.9%(89/1 005)、5.2%(52/1 000)和6.4%(64/1 002)。2016-2019年最小感染者分别为3、11、26和27岁。男性感染率均高于女性(P < 0.01)。除2016年外,学龄前儿童均无感染,其他文化程度组4年均有感染者。问卷调查结果显示,2016-2019年居民吃“鱼生”的比例分别为14.4%(22/153)、16.6%(25/151)、9.3%(14/150)和18.8%(29/154)。居民听说过华支睾吸虫病的比例,从2016年的13.7%(2/153)上升到2019年的55.8%(86/154)。结论 江西省信丰县国家监测点人群华支睾吸虫感染率仍然较高,人群吃“鱼生”的比例4年间维持在一定比例。

Abstract:

Objective To understand the prevalence of Clonorchis sinensis infection in Xinfeng County, so as provide scientific basis for formulating control strategies. Methods The Xinfeng County was divided into 5 areas according to the geographical location, and in each area one village was selected from a township to serve as the surveillance site, including Yu Village of Gubei Town, Zhangtang Village of Datangbu Township, Zhengao Village of Zhengping Township, Huangni Village of Xiniu Township, and Jiaokeng Village of Jiading Township. During 2016 to 2019, no less than 200 permanent residents aged 3 years or above were cluster sampled from each administrative village each year for fecal examination using the modified Kato-Katz thick smrar method (two slide reading/one sample) to estimate the status of Clonorchis infection. In addition, no less than 150 examinees were randomly selected for questionnaire survey on the knowledge, attitude and behavior towards clonorchiasis. Comparison of infection rate between groups was analyzed by chi-square test. Results From 2016 to 2019, the infection rate of C. sinensis was 9.3% (96/1 027), 8.9% (89/1 005), 5.2% (52/1 000) and 6.4% (64/1 002), respectively in each year, and the youngest infected people was at the age of 3, 11, 26 and 27 years, respectively. The infection rate in males was higher than that in females (P < 0.01). No infection was found in preschool children except in 2016, while the infection occurred in all other groups of different education levels in all years. The questionnaire survey indicates that from 2016 to 2019, the proportions of residents eating raw fish was 14.4% (22/153), 16.6% (25/151), 9.3% (14/150) and 18.8% (29/154), respectively. The proportion of residents having heard of clonorchiasis increased from 13.7% (2/153) in 2016 to 55.8% (86/154) in 2019. Conclusion The infection rate of C. sinensis remains high in the national surveillance site in Xinfeng County, and the proportion of residents eating raw fish keeps persistent in the four years.
