【摘要】：目的探索2004-2011年湖南省居民血吸虫感染的时空特征和变化规律。方法基于2004-2011年湖南省乡(镇)血吸虫病病情数据库,对湖南省居民血吸虫感染的时空特征进行描述与分析。结果 2004-2011年湖南省居民血吸虫感染率由3.0%下降至0.8%,但部分乡(镇)居民血吸虫感染率仍处于较高水平(P_(90)=2.1%),有螺水系沿岸居民血吸虫感染率高于其他地区。全局自相关分析显示,2004-2011年湖南省居民血吸虫感染率Moran’s I指数为0.34~0.53,均高于期望值且具有统计学意义(Z8.71,P0.05);局部G统计量热点分析显示,2004-2011年正热点"高-高"聚集乡(镇)主要位于洞庭湖沿岸,聚集乡(镇)数量为30~70个。SaTScan空间扫描发现,2004-2011年聚集区域内血吸虫病流行乡(镇)数为145~183个。结论 2004-2011年湖南省居民血吸虫感染率下降明显,但部分乡(镇)居民血吸虫感染率仍处于较高水平。2004-2011年湖南省居民血吸虫感染率存在明显正向空间自相关和聚集性,正热点"高-高"聚集区域可确定为下一步血吸虫病防治工作的重点。
[Abstract]:Objective to explore the temporal and spatial characteristics of Schistosoma japonicum infection in Hunan Province from 2004 to 2011. Methods based on the database of schistosomiasis in Hunan province from 2004 to 2011, the temporal and spatial characteristics of Schistosoma japonicum infection among residents in Hunan province were described and analyzed. Results the infection rate of Schistosoma japonicum in Hunan Province decreased from 3.0% to 0.8% from 2004 to 2011, but the infection rate of Schistosoma japonicum in some townships (towns) was still high (P90 = 2.1%). The infection rate of Schistosoma japonicum in the coastal areas of snail water system was higher than that Global autocorrelation analysis showed that the Moran's I index of Schistosoma japonicum infection rate in Hunan Province from 2004 to 2011 was 0.34 脳 0.53, which was higher than expected value and had statistical significance (Z8.71, P0.05). The hot spot analysis of local G statistics shows that the "high-high" concentrated townships (towns) are mainly located along the Dongting Lake from 2004 to 2011, and the number of concentrated townships (towns) is 30 ~ 70. SaTScan spatial scanning found that, In 2004-2011, the number of schistosomiasis endemic townships (towns) in the concentrated area was 145 / 183. Conclusion the infection rate of Schistosoma japonicum in Hunan Province decreased obviously from 2004 to 2011, but the infection rate of Schistosoma japonicum in some townships (towns) was still at a relatively high level. There was significant positive spatial autocorrelation and aggregation of Schistosoma japonicum infection rate in Hunan Province from 2004 to 2011. The "high-high" concentration area of positive hot spots can be identified as the focus of schistosomiasis prevention and control in the next step.
