Abstract: Objective　To analyze the endemic situation of schistosomiasis in Wuhu City from 2009 to 2018, so as to provide evidence for adjusting and developing the control strategy. Methods　The data regarding the endemic situation were retrospectively collected and analyzed in Wuhu City from 2009 to 2018. Results　The prevalence of human Schistosoma japonicum infections reduced from 0.450% in 2009 to 0.035% in 2018 in Wuhu City, and a reduction rate of 92.22% (χ2 = 1 6128.307, P < 0.01), and the prevalence of S. japonicum infections decreased from 0.483% in 2009 to 0 in 2018 (χ2 = 27.570, P < 0.01) in livestock. The area of snail habitats increased from 1 501.07 hm2 in 2009 to 4 408.62 hm2 in 2018, with an increase of 193.70%. No infected snails were found in Wuhu City since 2012, and no egg positives were detected in humans and livestock since 2016. Conclusions　Currently, the endemic situation of schistosomiasis is at a low level in Wuhu City; however, there are still factors affecting schistosomiasis transmission. In the future, the integrated strategy with emphasis on the control of infectious source and the surveillance?response system should be intensified to consolidate the achievements of schistosomiasis control.

摘要： 目的　分析芜湖市2009–2018年血吸虫病疫情，为调整、制定防控策略和措施提供依据。方法　收集2009–2018年芜湖市血吸虫病疫情数据，并进行描述性分析。结果　2009–2018年芜湖市人群血吸虫病患病率从2009年的0.450%下降至2018年的0.035%，下降了92.22%（χ2 = 16 128.307，P < 0.01）；家畜血吸虫感染率从0.483%下降为0（χ2 = 27.570，P < 0.01）。有螺面积由2009年的1 501.07 hm2增加到2018年的4 408.62 hm2，增加了193.70%。自2012年起未查到血吸虫感染性钉螺，自2016年起未再发现粪检阳性血吸虫病病人和病畜。结论　目前，芜湖市血吸虫病疫情已处于低流行状态，但有关血吸虫病流行与传播的因素依然存在。今后仍应加强以传染源控制为主的血吸虫病综合防治策略，完善和加强监测体系和应急响应机制，以巩固血防成果。
