中文摘要：

目的分析2005—2010年江苏省8个国家级血吸虫病监测点疫情状况，掌握各监测点的疫情变化趋势，为制定防治对策提供参考依据。方法根据《全国血吸虫病监测方案》，在江苏省设立8个监测点，开展病情、螺情等疫情纵向观察。结果2005—2010年8个监测点居民血吸虫血检阳性率、感染率整体呈下降趋势，分别由2005年的9．04％和0．22％下降至2010年的4．34％和0．02％，下降率分别为51．99％和90．91％；农民、渔民和商业服务等职业人群感染率较高，低年龄组学生感染度相对较高，未发现本地急性感染者。共调查7466．46hm^2环境，分别查出钉螺与感染螺面积2213．98hm^2和247．91hm^2，活螺密度和感染螺密度逐年下降，2010年未发现感染性钉螺，总体钉螺面积仍维持在较高水平。结论江苏省居民感染率处于较低水平，并呈逐年下降趋势；但对钉螺和传染源的监测和控制仍需进一步加强。

英文摘要：

Objective To understand the endemic situation of national surveillance sites in Jiangsu Province from 2005 to 2010,so as to provide the evidence for the prevention and control of schistosomiasis. Methods According to the national surveil？ lance protocol,a longitudinal surveillance on endemic situation of schistosomiasis was carried out in 8 national surveillance sites from 2005 to 2010. Results In general,the positive rates of blood tests and infection rates of Schistosoma japonicum decreased from 9.04% and 0.22% in 2005 to 4.34% and 0.02% in 2010,and the rates of decline were 51.99% and 90.91%,respectively.The endemic situation of farmers,fishermen and business men were relatively serious,and the infection degree of the low？aged group of students was relatively serious. No local acute schistosomiasis case was detected. A total of 7 466.46 hm2 of environmental sites were investigated,and the areas with living Oncomelania hupensis snails and infected snails were 2 213.98 and 247.91 hm2,respectively,the densities of living snails and infected snails decreased gradually,and no infected snail was found in 2010. However,the total areas with living snails and infected snails still keep a relative high level,and the density of infected snails rebounded in special sites. Conclusion The endemic situation of the national surveillance sites is under control,and the infection rate of human keeps at a low level in Jiangsu Province. The surveillance and control of snails and infection source should still be strengthened.
