目的探索基于地理信息系统和BGS-trap监测数据的时空分析方法在登革热疫情蚊媒控制效果评估中的应用。方法 2015年中山市出现登革热暴发疫情的社区应用BGS-trap进行伊蚊成蚊密度监测,7月27日起至8月5日基于监测数据利用Satscan连续进行每日时空扫描分析,评估是否存在蚊媒的时空聚集;地图绘制和结果可视化展示由ArcGIS实现。结果 2015年中山市G社区发现登革热本地病例3例,疫情持续11d,Satscan时空扫描分析结果显示5天发现5个应重点处理的区域。结论在登革热疫情中,BGS-trap、地理信息系统以及时空扫描分析方法的联合应用能够及时的确定热点地区,从而为该地区的灭蚊工作提供针对性的指导。
Objective To explore the application of spatiotemporal analysis based on GIS and BGS-trap data in the evaluation of mosquito control in dengue fever epidemic. Methods Community-based dengue outbreaks in Zhongshan City in 2015 were monitored for density of Aedes albopictus using BGS-trap. From July 27 to August 5, Satscan was used for continuous daily space-time scan analysis to assess the presence of mosquitoes Media space-time aggregation; mapping and visualization of results are implemented by ArcGIS. Results Three cases of local dengue fever were detected in G community of Zhongshan City in 2015, and the epidemic continued for 11 days. The results of Satscan spatio-temporal scanning analysis showed that 5 areas should be treated in 5 days. Conclusion In the dengue outbreak, the combination of BGS-trap, GIS and spatio-temporal scanning methods can timely identify hot spots and provide guidance for the anti-mosquito work in this area.
