2008-2011年芜湖县血吸虫病防治效果

Effect of schistosomiasis control in Wuhu County from 2008 to 2009

目的观察芜湖县血吸虫病防治效果。方法收集2008-2011年芜湖县人畜血吸虫感染、钉螺和感染性钉螺分布等调查资料,以及逐年防治措施实施情况,分析疫情变化和防治效果。结果2008-2011年,全县流行区居民血吸虫感染率由0.73%下降至0.25%,家畜感染率由0.37%降至0;感染性钉螺面积和密度分别由2.58 hm2和0.005 4只/0.1 m2降至0.46 hm2和0.001 6只/0.1 m2。结论芜湖县通过实施以传染源控制为主的综合防治措施,血吸虫病疫情已得到有效控制,流行水平已处于较低水平。但今后仍应加强传染源控制和钉螺控制力度,以巩固防治成果。

Objective To evaluate the effect of schistosomiasis control in Wuhu County from 2008 to 2009.Methods The data of the investigation on schistosome infections of residents and domestic animals,and the control measures were collected and analyzed in Wuhu County from 2008 to 2009.Results The schistosome infection rates in residents decreased from 0.73% in 2008 to 0.25% in 2011;the rates in domestic animals decreased from 0.37% in 2008 to 0 in 2011.The areas of habitats of infected Oncomelania snails decreased from 2.58 hm2 in 2008 to 0.46 hm2 in 2011;the densities of the infected snails decreased from 0.005 4 snails/0.1 m2 in 2008 to 0.001 6 snails/0.1 m2 in 2011.Conclusions Through the comprehensive control measures based mainly on infectious source control,the schistosomiasis endemic situation is effectively controlled,and the prevalent level is low in Wuhu County.However,we still need to strengthen the infectious source control and snail control so as to consolidate the control effect.
