Abstract

Objective: To investigate the Oncomelania hupensis snails spread and its spatio-temporal clustering characteristics in Suzhou City, Jiangsu Province from 2016 to 2023, so as to provide insights into precision control of O. hupensis snails in the City.

Methods: O. hupensis snail surveillance data in Suzhou City from 2016 to 2023 were collected, and the areas of O. hupensis snail spread and areas of emerging and re-emerging snail habitats were retrieved. The spatial distribution characteristics and clustering types and locations of environments with O. hupensis snail spread were investigated using global and local spatial auto correlation analyses with the software ArcGIS 10.7, and the clustering and cluster areas of O. hupensis snail spread were identified in Suzhou City using spatio-temporal scans with the software SaTScan 10.0.2.

Results: O. hupensis snail spread covered an area of 677 171 m² in Suzhou City from 2016 to 2023, including 376 230 m² emerging snail habitats and 300 941 m² re-emerging snail habitats. Global spatial autocorrelation analysis showed overall clustering of O. hupensis snail spread in Suzhou City from 2016 to 2023 (Moran's I = 0.066, P = 0.007), and there were spatial clustering of areas with O. hupensis snail spread in 2019 (Moran's I = 0.086, P = 0.001) and 2021 (Moran's I = 0.045, P = 0.003). Local spatial autocorrelation analysis showed clusters of O. hupensis snail spread in Suzhou City from 2016 to 2023, with high-high clusters in Guangfu Township and Dongzhu Street, and the high-high clusters of O. hupensis snail spread were mainly distributed in southwestern Suzhou City. Spatio-temporal scans identified two clusters of areas with O. hupensis snail spread and areas of re-emerging snail habitats in Suzhou City from 2016 to 2023, with large clustering areas found in Guangfu Township, Dongzhu Street, Tong'an Township and Wangting Township [relative risk (RR) = 22.34, log likelihood ratio (LLR) = 163 295.32, P < 0.001] and small clustering areas in Xukou Township, Mudu Township and Xiangshan Street (RR = 2.73, LLR = 921.92, P < 0.001).

Conclusions: There was spatial clustering of O. hupensis snail spread in Suzhou City from 2016 to 2023. Improved quality of O. hupensis snail control and intensified management of environments at a high risk of O. hupensis snail spread are recommended in Suzhou City.

[2016 - 2023年江苏省苏州市钉螺传播时空分布特征]。

目的：了解2016 - 2023年苏州市钉螺分布及时空聚类特征，为苏州市钉螺精准防控提供依据。方法：收集2016 - 2023年苏州市钉螺监测资料，检索苏州市钉螺流行区、新出现和再出现钉螺生境区。利用ArcGIS 10.7软件进行全局和局部空间自相关分析，调查苏州市钉螺传播环境的空间分布特征、聚类类型和分布位置；利用SaTScan 10.0.2软件进行时空扫描，确定苏州市钉螺传播的聚类和聚类区域。结果：2016 - 2023年苏州市钉螺传播面积为677 171 m2，其中新出现钉螺栖息地376 230 m2，再出现钉螺栖息地300 941 m2。全球空间自相关分析显示，2016 - 2023年苏州市钉螺传播总体呈聚类（Moran’s I = 0.066, P = 0.007）， 2019年（Moran’s I = 0.086, P = 0.001）和2021年（Moran’s I = 0.045, P = 0.003）钉螺传播区域呈空间聚类。局部空间自相关分析显示，2016 - 2023年苏州市湖北钉螺传播呈聚集性分布，高-高聚集在广府乡和东渚街，高-高聚集型主要分布在苏州市西南部。时空扫描结果显示，2016 - 2023年苏州市有2个钉螺传播区和钉螺再出现区，其中大聚集区在广福乡、东珠街、同安乡和望亭乡[相对危险度(RR) = 22.34，对数似然比(LLR) = 163 295.32, P < 0.001]，小聚集区在徐口乡、木都乡和象山街[RR = 2.73, LLR = 921.92, P < 0.001]。结论：2016 - 2023年苏州市钉螺传播存在空间聚集性。建议提高苏州市钉螺控制质量，加强钉螺传播高风险环境管理。
