2004-2015年湖北省阳新县预防控制血吸虫病效果分析

目的 评价2004-2015年阳新县预防控制血吸虫病的效果，为血吸虫病传播阻断和消除提供科学依据。方法 依据阳新县血吸虫病疫情层次和流行规律，采取综合治理的防治策略，持续实施卫生、水利、林业、农业等血防综合治理项目。分析比较2004-2015年该县血吸虫病疫情控制的效果。结果 阳新县实施血防综合治理整县推进后，全县推算病人数由2004年的22 240降至为2015年的1 471；人群感染率由2004年的8.57%降至2015年的0.16%；急性血吸虫感染（急感）病人由2004年的64例降至0，2009年以后未发生急感病例；耕牛感染率由2004年的8.87%降至0；钉螺面积和易感地带面积分别由2004年的3 446.21、1 111.59 hm2降至2015年的2 285.75、41.28 hm2；钉螺感染率由2004年的0.76%降至0。结论 自2004年实施血防综合治理整县推进的防治策略后，阳新县血吸虫病疫情显著下降，但要进一步巩固血防成果，仍需加大富河流域的治理力度，并强化家畜传染源的防控。

Effect of schistosomiasis control in Yangxin County,Hubei Province, 2004-2015

Objective To evaluate the effect of schistosomiasis control and prevention in Yangxin County from 2004 to 2015， so as to provide the evidence for improving the work of schistosomiasis transmission interrupted and elimination in the future. Methods According to the endemic types and endemic regularity of schistosomiasis in Yangxin County， the comprehensive control strategies were adopted， and the programs related to sanitation， water conservancy， forestry， and agriculture were implemented continuously. The schistosomiasis control effects in this county from 2004 to 2015 were analyzed and compared. Results After the implementation of the schistosomiasis comprehensive control strategies in Yangxin County， the calculated number of patients reduced from 22 240 in 2004 to 1 471 in 2015， the infection rate of residents reduced from 8.57% in 2004 to 0.16% in 2015， the number of patients with acute schistosome infection reduced from 64 in 2004 to 0， and no cases of acute schistosomiasis found since 2009. The infection rate of cattle decreased from 8.87% in 2004 to 0. The area with Oncomelania hupensis snails and the area of susceptible zone reduced from 3 446.21 hm2 and 1 111.59 hm2 in 2004 to 2 285.75 hm2 and 41.28 hm2 in 2015 respectively， and the schistosome?infection rate of snails reduced from 0.76% in 2004 to 0. Conclusions Since the comprehensive control strategy implemented from 2004， the endemic situation of schistosomiasis in Yangxin County has decreased significantly. However， the harness force of the Fu River as well as the control of infection source of livestock still should be strengthened to consolidate the control achievement.
