2014年湖北省血吸虫病国家监测点疫情分析

目的  分析湖北省2014年国家级血吸虫病疫情监测点疫情变化，了解湖北省血吸虫病流行现状，为制定血吸虫病防治对策提供科学依据。 方法  根据《全国血吸虫病监测方案（2011年修订版）》的要求，16个监测点开展了人群及家畜病情、螺情和相关因素调查，采用SPSS19.0软件统计分析监测结果。 结果  湖北省16个监测点居民感染率为0.18%，耕牛感染率为0，活螺平均密度为0.230只/0.11m2，活螺框出现率为7.987%，未发现感染性钉螺。 结论  湖北省血吸虫病国家监测点人畜感染率呈现持续下降，但钉螺面积依然维持在较高水平，血吸虫病传播风险仍在，应加强控制措施，防止疫情反弹。

Analysis of schistosomiasis prevalence trend from the national surveillance sites in Hubei Prov-ince in 2014

Objective  To investigate the endemic status and trend of schistosomiasis from the national surveillance sites in Hubei province in 2014 in order to provide the scientific basis for planning comparable prevention and control strategies. Methods  According to the national surveillance protocol(Revision in 2011), we conducted surveys on the incidences of schistosomisis in population and livestock as well as the prevalence of Oncomelania snails and risk factors associated with the infection in the 16 national surveillance sites in Hubei province, and the results were analyzed with software SPSS version 19.0. Results   The infection rate for residents and cattle was 0.18% and 0, respectively. The mean density of living snails was 0.230/0.11 m2.  The occurrence rate of frames with living snails was 7.987%, and no infected snails were found. Conclusion  Although endemic schistosomiasis in human and livestock tends to decline in the national surveillance sites in Hubei province, yet the areas with living snails are still large, suggesting that this situation should be managed with great efforts in order to minimize the risks of resurgence.
