摘要: 目的 结合地理信息系统(Geographic information system,GIS)分析2017年武汉市血吸虫病疫情,为今后血吸虫病防治工作提供参考。方法 根据2017年武汉市血吸虫病防治年报数据建立疫情资料空间数据库,使用ArcMap 10.2进行核密度分析。结果 2017年武汉市593个血吸虫病流行村主要分布在长江及其支流附近。核密度分析显示,流行村密度最高的3个区域分别位于蔡甸区西面(侏儒街道)、汉南区东面(纱帽街道)和新洲区西南角(阳逻街道);血吸虫病血检阳性人群密集分布于蔡甸区西面(侏儒街道),占全市血检阳性人口总数的34.23%;蔡甸区洪北街道东干村存栏牛数达492头,密度较高;实有钉螺面积密度较高的地区分布在蔡甸区西南角(消泗街道),占全市实有钉螺总面积的31.22%。2017年复现有螺面积36.60 hm2,其核密度较高的地区位于蔡甸区侏儒街道。活螺密度较高的地区位于汉南区的中部(洪北大队),平均密度为0.36只/0.1 m2。结论 武汉市血吸虫病疫情处于低流行水平,且在空间上分布不均匀;局部区域历史疫情较重,高危因素较集中,需加强监测。

Abstract: Objective To analyze the endemic sitaution of schistosomiasis based on geographic information system (GIS) in Wuhan City in 2017, so as to provide the reference for further schistosomiasis control activities. Methods According to the data of the annual report on the prevention and control of schistosomiasis in Wuhan City in 2017, the spatial database regarding the endemic situation of schistosomiasis was established and analyzed by ArcMap 10.2. Results The 593 schistosomiasis?endemic villages in Wuhan City were mainly located in the Yangtze River and its major tributaries. Kernel density analysis showed that the endemic villages of three regions with the highest density was located in the west of Caidian District (Zhuru Street), the east of Hannan District (Shamao Street) and the southwest corner of Xinzhou District (Yangluo Street). The sero?positive population was densely distributed in the West of Caidian District (Zhuru Street), which accounted for 34.23% of all seruo?positives in the city. There were 492 farming cattle fenced in Donggan Village in Hongbei Street of Caidian District. A higher density of the area with Oncomelania hupensis snails was located in the southwest region of Caidian District (Xiaosi Street), accounting for 31.22% of the total area with snails. In 2017, the re?emerging area with snails was 36.60 hm2. The high kernel density region with snails was located in Zhuru Street of Caidian District. The region with high density of living snails was located in the central region of Hannan District (Hongbei Production Brigade), the average density of living snails was 0.36 snails/0.1 m2. Conclusions The endemic situation of schistosomiasis is at a low level in Wuhan City, and the spatial distribution is not uniform. In some local areas, the historical endemic situation of schistosomiasis is serious and the high risk factors are more concentrated. It is necessary to strengthen the surveillance of schistosomiasis.
