2008-2014年九江市血吸虫病疫情及防控策略分析

目的 了解九江市血吸虫病疫情状况及变化趋势，为制定下一步防控策略提供科学依据。 方法 收集2008-2014年九江市血吸虫病防治数据，建立数据库，分析流行区范围变化、人畜感染率、血吸虫急性感染和突发疫情、感染性钉螺环境等指标。 结果 2014年与2008年相比，人、耕牛血吸虫病感染率分别下降了98.40%、92.54%，感染性钉螺面积从103.24 hm2下降为0，有螺框出现率与活螺密度分别从14.86%和0.334 5只/0.1 m2下降至6.89%和0.126 5只/0.1 m2。除2011年及2014年外，各年度均有血吸虫急性感染病例发现。 结论 九江市以传染源控制为主的防治策略效果显著，但血吸虫病传播风险仍然存在，仍需加强风险控制及防控措施的落实。

Analysis of epidemic situation and control strategy of schistosomiasis in Jiujiang City from 2008 to 2014

Objective To understand the epidemic situation of schistosomiasis in Jiujiang City， so as to provide the evidence for formulating further control strategy. Methods The data of schistosomiasis control were collected in Jiujiang City from 2008 to 2014. and the indicators including the annual schistosome infections of human and cattle， acute schistosome infection， outbreak of schistosomiasis endemic， schistosome infected Oncomelania hupensis snails were analyzed statistically. Results Compared with 2008， in 2014， the infection rates of schistosomiasis declined by 98.40% and 92.54% in human and cattle respectively. The area of schistosome infected snails decreased from 103.24 hm2 to zero. The occurrence rate of frames with snails and density of living snails declined from 14.86% and 0.334 5/0.1 m2 to 6.89% and 0.126 5/0.1 m2， respectively. The acute schistosomiasis infection cases occurred except 2011 and 2014. Conclusion The control strategy emphasizing on infection sources control is effective in Jiujiang City， but the risk of schistosomiasis still exists， and the risk control and schistosomiasis control strategy should be strengthened
