目的了解沙市区2009-2013年血吸虫病综合治理效果,为防治策略的制定或调整提供依据。方法收集2009-2013年沙市区血吸虫病综合治理资料,分析人、畜病情及螺情变化。结果 2009-2013年,沙市区人群和耕牛血吸虫感染率分别由2.24%和1.92%下降到0.63%和0,分别下降了71.88%和100%;钉螺面积由760.40 hm2下降至715.08hm2,下降率为5.69%,活螺框出现率和活螺平均密度分别由26.32%和0.67只/0.1 m2下降到18.30%和0.53只/0.1 m2,分别下降了30.47%和20.90%。2012-2013年未查到感染性钉螺。结论以传染源控制为主的综合防治措施可显著降低人、畜感染率,能有效控制螺情。
Objective To understand the comprehensive treatment effect of schistosomiasis in Shashi District from 2009 to 2013 and provide the basis for the formulation or adjustment of prevention and control strategies. Methods The data of comprehensive treatment of schistosomiasis in Shashi district from 2009 to 2013 were collected to analyze the changes of human and livestock conditions and snail status. Results In 2009-2013, the infection rate of schistosomiasis in Shashi district decreased from 2.24% and 1.92% to 0.63% and 0, respectively, with a decrease of 71.88% and 100% respectively. The snail area decreased from 760.40 hm 2 to 715.08 hm 2, Was 5.69%. The incidence of live screw and average density of live snails decreased from 26.32% and 0.67 /0.1 m2 to 18.30% and 0.53 /0.1 m2 respectively, down by 30.47% and 20.90% respectively. Infectious snails were not detected in 2012-2013. Conclusion The comprehensive prevention and control measures based on infection source control can significantly reduce infection rate of people and livestock and effectively control the snail.
