目的了解全国血吸虫病流行状况,为制订血吸虫病防治对策提供科学依据。方法依照《全国血吸虫病监测方案》,开展全国血吸虫病疫情监测点工作,统计与分析2005年监测结果。结果80个全国监测点人群血检阳性率17．22%;人群粪检阳性率2．04%,人群感染度几何均数0．52:牛、羊和猪的感染率分别为10．59%、3．05%和0．55%;活螺平均密度0．77只/0．11m~2,感染螺平均密度0．002 0只/0．11m~2,钉螺感染率0．26%。结论一、二类流行村疫情严重,需要加强传染源控制。渔船民和农民的感染率较高,应根据防治目标,选择重点人群,实施人群健康教育与查治病措施。低度流行区疫情不稳定,应加强监测巩固和综合治理工作。

Report of the result of ntional surveillance for schistosomiasis in China, 2005

Objective To understand the whole national endemic situation of schistosomiasis,so as to provide scientific evidence for making out prevention and control measures for it.Methods To carry out the whole national surveillance work of schistosomiasis according to the national surveillance protocol, and to analyze the surveillance results.Results Among 80 national surveillance sites,the average positive rate,with sera-test,of the resident was 17.22%,the average positive rate,with stool examination,of the resident was 2.04%,the geometrical mean of EPG of the residentt was 0.52.The infection rate of the cattles,goats and pigs was 10.59%,3.05% and 0.55%,respectively.The average density of the living snail was 0.77/0.11m2,the average desity of the positive snail was 0.0020/0.11m2,the snail infection rate was 0.26%.Conclusion Schistosomiasis was seriously endemic in the endemic villages with first and second level, the control of infection sources should be enhanced.The infection rate of fisher and farmer was relatively very high.so health education and examination and treatment should be carried out for them as the focal people.The situation in low endemic areas was instable, surveillance and comprehensive management should be strengthened in these areas.
