OBJECTIVE
To explore the application of space-time scan statistics in the early warning of distribution of schistosome infected Oncomelania hupensis snails.
METHODS
The data of distribution of infected snails in Anhui Province from 2006 to 2012 were collected, and a spatial database was established by ArcGIS 9.3. The prospective spatial-temporal cluster analysis was done by SaTscan 9.1.1 at the village level.
RESULTS
Four space-time clusters, which were distributed over the Yangtze River and its branch rivers, were detected.
CONCLUSION
The space-time scan statistics could detect the distribution of infected snails early, and the space-time clusters found were the key and difficult points of schistosomiasis control in Anhui Province.
目的
探讨时空扫描统计法在日本血吸虫感染钉螺分布预警中的应用。
方法
收集2006 - 2012年安徽省感染钉螺分布数据，利用ArcGIS 9.3建立空间数据库。在村级水平上采用SaTscan 9.1.1进行前瞻性时空聚类分析。
结果
检测到4个时空聚集区，分布于长江及其支流。
结论
时空扫描统计法可早期发现感染钉螺的分布情况，所发现的时空聚集区是安徽省血吸虫病防治的重点和难点地区。
