摘　　要：目的揭示血吸虫病的流行特征和不同监测点的流行特点。方法应用Barbour双宿主模型计算传播动力学指标。结果各监测点人和耕牛的基本繁殖率均较低,血吸虫对牛的传播速率明显高于对人的传播速率,表明牛宿主或病牛在血吸虫病的传播中起着更重要的作用,各监测点亦表现出不同的传播特点。结论Barbour双宿主模型较之其他单终宿主模型复杂,但更能反映日本血吸虫病传播的情况。Objective To reveal the epidemiological characteristics of schistosomiasis and the differences among the surveillance sites. Method In four surveillance sites of Sichuan Province, Barbour＇s two-host model was used to estimate the indices of the transmission dynamics. Result In each schistosomiasis surveillance site, the net reproductive number was much less. The cattles＇ transmission capacity was much higher than human＇s indicated that cattle was much more important in the transmission of schistosmiasis. In addition, each site had different epidemiological characteristics. Conclusion Barbour＇s two-host model is more complicated than other single-host models and can further demonstrate the situation of schistosmiasis japonica.
