【摘要】 目的评价安徽省规划达标地区血吸虫病疫情状况,为制定防治策略和措施提供科学依据。方法收集2008～2010年规划达标地区人畜筛查化疗、钉螺控制、传染源控制等防治工作资料和疫情监测点资料,评价防治效果,分析疫情变化趋势。结果通过防治策略的实施,至2010年,规控县人群感染率降至0.58%,较2008年下降了13.4%;耕牛感染率降至0.67%,较2008年下降了11.8%;钉螺面积上升至30156.34hm~2,较2008年上升了5.3%;活螺密度上升至0.81只/0.11m~2,较2008年上升了15.7%;感染螺密度0.00066只/0.11m~2,与2008年基本持平;急感发生例数分别为19、25和16例。规阻县人群感染率降至0.20%,较2008年下降了13.0%;耕牛感染率降至0.05%,较2008年下降了37.5%;钉螺面积上升至410.08hm~2,较2008年上升了2.1%;活螺密度上升至0.92只/0.11m~2,较2008年上升了95.7%;无急感和感染螺存在。结论 3年来,两类达标地区人畜感染率均进一步下降,钉螺面积和活螺密度均出现回升趋势:规控县感染螺密度和急感疫情未得到有效控制。更多还原

【Abstract】 Objective To evaluate the endemic situation of schistosomiasis in the counties of Anhui province programmed to reach the criteria of transmission control or interruption,and provide scientific basis for control strategies.Methods The data were retrospectively collected in the counties programmed to reach the criteria of transmission control or interruption that included the schistosomiasis diagnosis and chemotherapy of residents and livestock,snail survey and control,and infection source control from 2008 to 2010.The changes of epidemic situation and the effectiveness of control in the counties were analyzed and evaluated. Results In the counties programmed to reach the criteria of transmission control,the infection rates of population and cattle in 2010 reduced by 13.4%and 11.8%,compared with 2008,to 0.58%and 0.67%,respectively. In 2010,the areas with snails was 30 156.34hm2,rising by 5.3%compared with that of 2008;the density of living snails rose to 0.81/0.11m~2,15.7%higher than that in 2008;the density of infection snails was 0.000 66/ 0.11m~2,keeping almost unchanged.The number of acute cases in 2008,2009 and 2010 was 19,25 and 16, respectively.In the counties programmed to reach the criteria of transmission interruption,the infection rates of population and cattle in 2010 reduced to 0.20%and 0.05%,13.0%and 37.5%lower than those in 2008.respectively. The areas with snails rose to 410.08hnr in 2010,2.1%higher than that in 2008;the density of living snails rose to 0.92/0.11m~2,95.7%higher than that in 2008;no infected snails and no acute cases were found. Conclusion In the counties programmed to reach the criteria of transmission control or interruption,the infection rates of population and cattle reduced in past three years,but the areas with snails and the density of living snails taken a rising trend.In the counties programmed to reach the criteria of transmission control,the acute schistosomiasis and infected snails was not controled effectively.更多还原
