Abstract: Objective To assess the schistosomiasis endemic situation in the national surveillance sites in Hubei Province， so as to provide the evidence for the prevention and control of schistosomiasis. Methods According to the national surveillance protocol，a longitudinal surveillance of endemic situation of schistosomiasis was carried out in 16 national surveillance sites from 2005 to 2010. Results In general，the positive rates of IHA，Kato?Katz technique and infection rates of Schistosoma japonicum decreased from 15.67%，10.93% and 1.71% in 2005 to 10.48%，8.54% and 0.90% in 2010，and declined by 33.12%，22.70% and 47.95%，respectively. The infection rates of S. japonicum of the male were higher than that of the female，and the peak infec? tion rates were in the groups aged above 30 years. The endemic situation of fishermen and farmers were relatively serious. The in? fection rates of S. japonicum in cattle decreased from 11.69% in 2005 to 1.41% in 2010，and declined by 88.01%（χ2 =298.79， P <0.001） . The areas with infected Oncomelania hupensis snails，the densities of living snails，the rates of infected snails and the densities of infected snails decreased by 90.88%，61.66%，80.00% and 92.00%，respectively. Conclusion The schistosomiasis endemic situation in the national surveillance sites in Hubei Province mitigates in 6 years，but the prevention is still a very daunt? ing task.

摘要： 目的 目的 分析湖北省血吸虫病国家监测点疫情流行趋势， 为全省血吸虫病防治工作提供科学依据。方法 方法 根据 《全国血吸虫病监测方案》， 对湖北省16个国家监测点开展血吸虫病疫情纵向观察， 并对监测数据采用统计软件进行分析 和疫情评估。结果 结果 2005-2010年， 16个监测点居民血检阳性率、 粪检阳性率和血吸虫感染率总体呈下降趋势， 分别由 2005年的15.67%、 10.93%和1.71%下降到2010年的10.48%、 8.54%和0.90%， 下降率分别为33.12%、 22.70%和47.95%； 男性 血吸虫感染率均高于女性； 居民血吸虫感染高峰主要在30岁以上人群， 渔民血吸虫感染率较高， 学生感染率较低。耕牛血 吸虫感染率也呈下降趋势， 由2005年11.69%下降到2010年的1.41%， 下降了88.01% （χ2 = 298.79， P < 0.001）。6年间， 监 测点感染性钉螺面积、 活螺平均密度、 钉螺感染率和感染性钉螺平均密度均呈下降趋势， 分别下降了90.88%、 61.66%、 80.00%和92.00%。结论 结论 湖北省国家监测点血吸虫病疫情总体呈逐年下降趋势， 但防治任务仍然十分艰巨。
