Schistosomiasis control effect of county promotion and comprehensive control interventions in lake and marshland regions

目的评价荆州市整县推进、综合治理控制血吸虫病效果。方法采用回顾性调查方法,收集2006-2010年荆州市9个县(市、区)血吸虫病疫情资料。2010年11月抽查考核评估人群、耕牛血吸虫感染情况。结果 2006-2010年荆州市血吸虫病疫情呈下降趋势。2010年全市人群血吸虫感染率为2.22%,比2006年(5.15%)下降了56.89%,未发现急性血吸虫病病例,连续5年未发生突发疫情。2010年耕牛血吸虫感染率为1.87%,较2006年(8.04%)下降了81.72%;实有钉螺面积31070.61hm2,比2006年减少了1187.15hm2(3.68%)。感染性螺点面积321.70hm2,比2006年减少了795.45hm2(71.20%);感染螺密度和钉螺感染率分别比2006年下降了63.76%和64.74%。结论荆州市实施整县推进、综合治理项目以来,血防工作取得了明显成效,疫情得到了有效控制。

Objective To evaluate the schistosomiasis control effect of county promotion and comprehensive control interventions in Jingzhou City.Methods The data of schistosomiasis endemic situation of 9 counties（cities,districts） in Jingzhou City from 2006 to 2010 were collected by a retrospective survey method,and the schistosome infection situation of residents and cattle were selectively examined in November,2010.Results The endemic situation in Jingzhou City from 2006 to 2010 presented a decline tendency.Compared to the infection rate of residents in 2006（5.15%）,that in 2010（2.22%） decreased by 56.89%,and no acute schistosomiasis cases were found.No sudden epidemic happened in the consecutive 5 years.The infection rate of cattle dropped from 8.04% in 2006 to 1.87% in 2010,with a reduction rate of 81.72%.The snail area and area with infected snails in 2010 were 31 070.61 hm2 and 321.70 hm2,respectively,with reduction rates of 3.68% and 71.20%,respectively,compared to those in 2006.Compared to 2006,the snail density and infection rate of snails in 2010 decreased by 63.76% and 64.74%,respectively.Conclusions After the implementation of the project with county promotion and comprehensive control interventions in Jingzhou City,the schistosomiasis control work has obtained obvious achievement,and the endemic situation has been controlled effectively.
