【摘要】：目的了解湖北省江陵县血吸虫病流行区野粪分布及阳性情况,并对其空间分布特征进行分析描述,以及时发现传染源,为制定相应的监测与响应措施提供科学依据。方法 2011年在江陵县血吸虫病流行区,将疫情按严重程度分为高、中、低3层,每层抽取5个自然村作为调查点,选取江滩和沟渠作为调查环境,收集野粪并采用尼龙绢袋集卵孵化法检查。此外,采用描述性分析和空间分析方法,对野粪进行空间分布特征描述和回归分析。结果现场调查共收集野粪701份,野粪平均密度为0.055 6份/100 m~2;检出阳性野粪82份,野粪阳性率为11.70%。回归分析结果表明,野粪阳性率与人群感染率、感染性钉螺面积和耕牛存栏数之间存在空间相关性,其模型的校正R2值为0.58。结论江陵县野粪阳性率与人群感染率、感染性钉螺面积及耕牛存栏数之间存在空间正相关关系,可以根据其空间分布特征进行重点防控。
[Abstract]:Objective to understand the distribution and positive situation of wild feces in endemic areas of schistosomiasis in Jiangling County Hubei Province and to analyze and describe the spatial distribution characteristics so as to find out the source of infection in time and provide scientific basis for making corresponding monitoring and response measures. Methods in 2011, in Jiangling County schistosomiasis endemic area, the epidemic situation was divided into three levels according to severity, 5 natural villages were selected from each layer as investigation points, and riverbanks and ditches were selected as investigation environment. The feces were collected and examined by nylon silk bag egg hatching method. In addition, descriptive analysis and spatial analysis were used to describe the spatial distribution characteristics and regression analysis of wild dung. Results A total of 701 samples of wild feces were collected, the average density of wild feces was 0.055 / 100mm2, 82 of them were positive, and the positive rate of wild feces was 11.70. The results of regression analysis showed that there was a spatial correlation between the positive rate of wild feces and the infection rate, the area of infected snails and the number of farm cattle. The corrected R2 value of the model was 0.58. Conclusion the positive rate of wild feces in Jiangling County is positively correlated with the infection rate of population, the area of infected snails and the number of farm cattle, which can be controlled according to its spatial distribution.
