目的：研究湖沼垸内型血吸虫病流行区血吸虫病疫情变化与经费投入和防治费用的关联性，为优化血吸虫病防治策略提供参考。方法选择江陵县为研究区，采用直线相关与回归法分析当地2006-2013年血吸虫病疫情；采用两阶段最小二乘法与路径递归模型分析经费投入与防治费用对当地疫情变化的可能影响。结果2006-2013年，江陵县人群校正感染率、耕牛存栏数与钉螺面积分别下降了77.42%、76.34%和19.43%；钉螺感染率与人群血检、粪检阳性率及耕牛感染率均呈显著相关，且与耕牛感染率呈直线回归关系（P均<0.05）。各级投入与人群血检和粪检阳性率、耕牛和钉螺感染率，以及各类费用与人群粪检阳性率、耕牛和钉螺感染率的回归模型均有统计学意义（P均<0.05），但各类费用与人群血检阳性率回归模型无统计学意义（P>0.05）；影响人群血检阳性率、人群粪检阳性率、耕牛感染率和钉螺感染率的分别为县级投入、综合治理费用、人工费用与查治病费用、国家级投入与查治病费用（P均<0.05）。结论2006-2013年，江陵县血吸虫病疫情变化与各级投入、防治费用均有关联；各疫情指标相互显著相关的现象提示应开展综合性监测体系研究。

Objective To investigate the correlations between inputs and costs and endemic situation of schistosomiasis in inner embankment,so as to provide the references for the strategy optimization of schistosomiasis control. Methods Jiangling County was selected as the study field. The correlation and regression analyses were applied to analyze the endemic situation of schistosomiasis in Jiangling County from 2006 to 2013. The methods of two?stages least squares and path analysis were applied to analyze the impacts between costs and inputs and endemic situation of schistosomiasis. Results The adjusted infection rate of population,number of bovines and Oncomelania hupensis snail areas reduced by 77.42%,76.34%and 19.43%,respectively in Jiangling County from 2006 to 2013. The correlations between the infection rate of snails and the population positive rates of blood and fecal exams,and the infection rate of bovines were significant(all P<0.05);and there was a significant linear regres? sion between the infection rates of snails and bovines(P<0.05). There were statistically significant regressions between inputs at different levels and the population positive rates of blood and fecal exams,and the infection rates of bovines and snails,as well as between the costs and the population positive rate of fecal exams and the infection rates of bovines and snails(all P<0.05),whereas there was no statistically significant regression between the costs and the population positive rate by blood exams (P>0.05). The inputs at county level had an impact on the population positive rate of blood exams;the costs of comprehensive treatment had an impact on the population positive rate of fecal exams;the costs of human labor and measures for exams and treatments had an impact on the infection rate of bovines;the inputs at national level and the costs of measures for exams and treatments had an impact on the infection rate of snails(all P<0.05). Conclusion The inputs and costs of schistosomiasis con?trol were related to the epidemic situation of schistosomiasis in Jiangling County from 2006 to 2013;therefore,it is necessary to develop a comprehensive surveillance system as substitute for the current indexes on schistosomiasis control.
