摘要
目的探索序贯实施"土地整理和以机代牛"措施控制血吸虫病的效果。方法选择潜江市熊口农场和运粮湖农场为试区,序贯实施土地整理和以机代牛措施,观察血吸虫病疫情变化。结果 2012年人群血吸虫感染率比2008年下降了78.90%,其中血检阳性率下降47.88%(χ2=368.58,P<0.01),粪检阳性率下降了55.88%(χ2=29.92,P<0.01);2008年耕牛感染率为2.54%,此后成为无牛区。有螺面积下降54.78%;活螺框出现率下降76.49%(χ2=11.34,P<0.01);活螺平均密度下降72.63%(χ2=12.86,P<0.01);2009年起,未查到感染性钉螺。结论序贯实施土地整理和以机代牛措施,可有效控制血吸虫病传播。
Objective To evaluate the schistosomiasis control effect of sequential farmland consolidation and replacing bo- vine with machine. Methods Two farmlands of Qianjiang City were selected as experimental districts, and the sequential imple- menting farmland consolidation and replacing bovine with machine were carried out. The schistosomiasis epidemic situation was ob- served continuously. Results From 2008 to 2012, the human schistosome infection rate decreased by 78.90%, in which the sero- positive rate decreased by 47.88%（ X2 = 368.58, P 〈 0.01） and the stool positive rate decreased by 55.88% （ X2 =29.92, P 〈 0.01 ）. The schistosome infection rate of cattle was 2.54% in 2008, but from 2009, there were no cattle in the area. The Oncomela- nia snail area decreased by 54.78%, and the rate of frames with living snails and the mean density of living snails decreased by 76.49% and 72.63% （ X2 = 11.34, 12.86,P 〈 0.01） respectively. Since 2009, no infected snails were found. Conclusion The se- quential implementing farmland consolidation and replacing cattle with machine can effectively control the transmission of schisto- somiasis.
