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。
Objective To understand the epidemic situation and trend of schistosomiasis in Jiujiang City and provide a scientific basis for making the next prevention and control strategy. Methods The data of prevention and treatment of schistosomiasis in Jiujiang city from 2008 to 2014 were collected and the database was established. The changes of epidemic area, infection rate of human and livestock, acute and chronic outbreaks of schistosomiasis, and snail infectivity were analyzed. Results Compared with 2008, the prevalence of schistosomiasis in human and cattle decreased by 98.40% and 92.54%, respectively, and the area of infected snails decreased from 103.24 hm2 to 0, the incidence of snail box and live snail density decreased from 14.86% And 0.334 5 /0.1 m2 dropped to 6.89% and 0.126 5 /0.1 m2. In addition to 2011 and 2014, the annual schistosomiasis acute infection were found. Conclusion The prevention and cure strategies dominated by infection sources in Jiujiang City are significant. However, the risks of transmission of schistosomiasis still exist, and the implementation of risk control and prevention and control measures should be strengthened.
