Due to the success of the national schistosomiasis control programme in China, transmission has been sufficiently reduced in many areas to severely limit identification of areas at risk by conventional snail surveys only. In this study, we imported Google Earth technology and a Global Positioning System (GPS) into the monitoring system for schistosomiasis surveillance of the banks of the Yangtze River in Jiangsu Province, China.
A total of 45 sites were selected and the risk was assessed monthly by water exposure of sentinel mice at these sites from May to September in 2009 and 2010. The results were assembled and broadcast via the Google Earth platform.
The intensity of schistosomiasis transmission showed peaks of risk in June and September of 2009, while there was only one small peak in June in 2010 as the number of detected positive transmission sites dropped dramatically that year thanks to improved mollusciciding. River ports were found to be areas of particular risk, but ferry terminals and other centres of river-related activities were also problematic.
The results confirm that the surveillance system can be rapidly updated and easily maintained, which proves the Google Earth approach to be a user-friendly, inexpensive warning system for schistosomiasis risk.
由于中国全国血吸虫病控制规划的成功，在许多地区的传播已得到充分减少，仅通过常规钉螺调查来识别有风险的地区已严重受限。在这项研究中，我们将谷歌地球技术和全球定位系统（GPS）引入中国江苏省长江岸线血吸虫病监测系统。
共选择了 45 个地点，并于 2009 年和 2010 年 5 月至 9 月每月通过在这些地点暴露哨鼠来评估风险。结果通过谷歌地球平台进行汇总和广播。
2009 年 6 月和 9 月的血吸虫病传播强度显示出风险高峰，而 2010 年 6 月仅出现一个小高峰，因为当年由于改进了灭螺工作，检测到的阳性传播地点数量急剧下降。发现河港是特别危险的地区，但渡口和其他与河流相关的活动中心也是有问题的。
结果证实该监测系统可以快速更新且易于维护，这证明谷歌地球方法是一种用户友好且经济实惠的血吸虫病风险预警系统。
