Abstract:

Objectives To explore a new mode of malaria elimination through the application of digital earth system in malar? ia epidemic management and surveillance. Methods While we investigated the malaria cases and deal with the epidemic areas in Jiangsu Province in 2011，we used JISIBAO UniStrong G330 GIS data acquisition unit（GPS）to collect the latitude and longitude of the cases located，and then established a landmark library about early?warning areas and an image management system by using Google Earth Free 6.2 and its image processing software. Results A total of 374 malaria cases were reported in Jiangsu Province in 2011. Among them，there were 13 local vivax malaria cases，11 imported vivax malaria cases from other provinces，20 abroad imported vivax malaria cases，309 abroad imported falciparum malaria cases，7 abroad imported quartan malaria cases（Plasmodi? um malaria infection），and 14 abroad imported ovale malaria cases（P. ovale infection） . Through the analysis of Google Earth Mapping system，these malaria cases showed a certain degree of aggregation except the abroad imported quartan malaria cases which were highly sporadic. The local vivax malaria cases mainly concentrated in Sihong County，the imported vivax malaria cases from other provinces mainly concentrated in Suzhou City and Wuxi City，the abroad imported vivax malaria cases concentrated in Nanjing City，the abroad imported falciparum malaria cases clustered in the middle parts of Jiangsu Province，and the abroad im? ported ovale malaria cases clustered in Liyang City. Conclusion The operation of Google Earth Free 6.2 is simple，convenient and quick，which could help the public health authority to make the decision of malaria prevention and control，including the use of funds and other health resources.

摘要：

目的 目的 通过数字地球系统应用于疟疾疫情管理和监测， 探索消除疟疾的新模式。方法 方法 对2011年江苏省疟疾病例进行个案调查和疫点处置， 同时利用集思宝 UniStrong G330 GIS数据采集器采集患者居住地的经纬度， 再利用数字地球系统 （Google Earth）Free 6.2及其图片管理软件， 建立疟疾病例预警点地标库和图片管理系统。结果 结果 2011年江苏省共报告疟疾374例。其中本地感染间日疟13例， 国内外省输入性间日疟11例， 国外输入性间日疟20例， 国外输入性恶性疟309 例， 国外输入性三日疟7例， 国外输入性卵形疟14例。从Google Earth制图可以清晰地发现， 除输入性三日疟呈高度散发外， 其他疟疾病例都有一定的聚集性。本地感染间日疟病例主要集中在泗洪县， 国内外省输入性间日疟主要集中在苏州市和无锡市， 国外输入性间日疟主要集中在南京市， 国外输入恶性疟主要集中在苏中地区， 国外输入性卵形疟主要集中在溧阳市。结论 结论 Google Earth应用于疟疾疫情管理操作简便快捷， 图文直观清晰， 能为卫生主管部门合理配置疟防资源、 消除疟疾决策提供技术支撑参考。
