南京市浦口区江滩综合治理控制血吸虫病效果

Effects of comprehensive schistosomiasis control in marshlands of Pukou District,Nanjing City

目的观察南京市浦口区江滩综合治理控制血吸虫病效果,为制定防治策略提供科学依据。方法收集2004-2013年浦口区血吸虫病疫情及防治措施资料,分析比较不同年份不同防治措施人群、家畜、钉螺血吸虫感染率变化。结果 2013年全区钉螺面积384.09 hm2,比2004年的1137.61 hm2下降了66.24%,2004年感染性钉螺面积572.02hm2,钉螺血吸虫感染率为0.18%,2008年后未查见感染性钉螺。2004年人群感染率为3.55%,2007年下降为0.02%,2008年后未再查到血吸虫病人。结论南京市浦口区实施血吸虫病综合治理措施后疫情稳定;但仍需对既往有螺环境进行监测及综合防治以巩固效果。

Objective To evaluate the effects of comprehensive schistosomiasis control in marshlands of Pukou District,Nanjing City so as to provide the evidence for developing the strategy of the disease control. Methods The information of the prevention and control of schistosomiasis was collected in Pukou District from 2004 to 2013. The variations of the infection rates of human,livestock and Oncomelania hupensis snails were analyzed. Results In 2013,the area with snails in the entire district was 384.09 hm2,which was 66.24% decrease compared to 1137.61 hm2 in 2004. Moreover,after 2008,no infected-snails and schistosomiasis patients were found,and both the density of live snails and serum positive rate of schistosomiasis declined with years. Conclusions After the comprehensive prevention and control is conducted,the schistosomiasis situation in Pukou District is stable. However,in order to consolidate the results,it is still essential to continue monitoring the previous infected snail environments and implementing the comprehensive prevention and control measures.
