我们比较了世界银行贷款项目（WBLP）结束后和结束后六年中国西南地区血吸虫病空间聚集的变化，该项目的控制策略集中于大规模化疗。寄生虫学数据是通过 1999-2001 年和 2007-2008 年进行的标准化调查获得的。使用两种替代空间聚类方法来识别案例的空间聚类：Anselin 的局部 Moran’s I 检验和 Kulldorff 的空间扫描统计。 WBLP结束后发现血吸虫病负担大幅减少，但整个研究区域的血吸虫病空间范围并未减少。两时期空间集群持续出现在成都平原、长江流域、澜沧江流域三个区域，并经常涉及5个县。这些研究结果表明，尽管负担显着减轻，但中国西南丘陵山区仍面临血吸虫重新出现的风险。我们的结果有助于突出综合控制计划可以重点关注的具体地点，以加快消除中国的血吸虫病。
We compared changes in the spatial clustering of schistosomiasis in Southwest China at the conclusion of and six years following the end of the World Bank Loan Project (WBLP), the control strategy of which was focused on the large-scale use of chemotherapy. Parasitological data were obtained through standardized surveys conducted in 1999–2001 and again in 2007–2008. Two alternate spatial cluster methods were used to identify spatial clusters of cases: Anselin’s Local Moran’s I test and Kulldorff’s spatial scan statistic. Substantial reductions in the burden of schistosomiasis were found after the end of the WBLP, but the spatial extent of schistosomiasis was not reduced across the study area. Spatial clusters continued to occur in three regions: Chengdu Plain, Yangtze River Valley, and Lancang River Valley during the two periods, and regularly involved five counties. These findings suggest that despite impressive reductions in burden, the hilly and mountainous regions of Southwest China remain at risk of schistosome re-emergence. Our results help to highlight specific locations where integrated control programs can focus to speed the elimination of schistosomiasis in China.
