目的 目的 掌握松滋市新江口镇血吸虫病流行状况。 方法 方法 收集松滋市新江口镇2004-2013年血吸虫病疫情资料， 分析血吸虫病病情、 螺情变化趋势。 结果 结果 2004-2013年全镇有螺面积在193.2～185.3 hm2 。感染性钉螺平均密度最高的 年份为2007年、 达0.000 70只/0.1 m2 ，2011年以后则未再查见感染性钉螺。2005年居民血检阳性率和血吸虫感染率分别 为9.46%和7.36%， 2013年则分别下降至3.27%和0.57%。2004年和2005年曾发生7例急性感染病例， 2006年以后则未再 发现。2004年耕牛血吸虫感染率为18.27%， 2007年起降至5%以下， 2013年则淘汰了全部耕牛。结论 结论 新口镇血吸虫病 流行已降至较低水平， 但要实现血吸虫病传播控制目标， 必须继续实施以传染源控制为主的综合防治措施。

Analysis of schistosomiasis epidemic situation in Xinjiangkou Township,Sonzi City,from 2004 to 2013

Objective To master the status of schistosomiasis transmission in Xinjiangkou Township,Sonzi City,from 2004 to 2013.

The positive rate of blood tests was 9.46%and schistosomiasis infection rate was 7.36%in 2005,and the posi-tive rate of blood tests was 3.27%and schistosomiasis infection rate was 0.57%in 2013. There were 7 cases of acute schistosomia-sis in 2004 and 2005,respectively,and there were no acute schistosomiasis patients after 2006. The schistosome infection rate of cattle was 18.27%in 2004,and after 2007,the infection rate decreased below 5%. In 2013,all the cattle were obsoleted. Conclu-sion The schistosomiasis transmission has reduced to a low level in Xinjiangkou Township.
