To understand the schistosomiasis control progress and endemic situation, so as to provide the evidence for formulating the strategy of schistosomiasis elimination in Sichuan Province.
The schistosomiasis history data, working reports of schistosomiasis prevention and control, schistosomiasis surveillance data, and data of schistosomiasis prevention and control capacity were collected and analyzed for the schistosomiasis control progress and epidemic situation in Sichuan Province from 2004 to 2015.
There were 63 schistosomiasis endemic districts in 11 cities in Sichuan Province, and the standard of schistosomiasis transmission interruption was achieved in the whole province in 2015. Currently, the area with snails was 2 537.54 hm, and there were 1 769 advanced schistosomiasis patients. From 2004 to 2015, the accumulated survey area with snails was 433 065.80 hm, and the area of snail control by molluscicides was 251 259 hm. There were 26.017 144 million person-times of schistosomiasis blood tests and 7.89 million person-times of chemotherapy. There were 1.276 117 million head-times of cattle that received the schistosomiasis examinations. The schistosomiasis patients and livestock and the area with snails were decreased year by year. Since 2010, there were no local schistosome-infected residents and livestock and since 2004, there were no schistosome-infected snails. However, in some area, the professional personnel were less, the technology and hardware lagged behind, and the schistosomiasis prevention and control capacity was weak.
Sichuan Province achieved the standard of schistosomiasis transmission interruption in 2015. In the future, the comprehensive schistosomiasis prevention and control strategy still should be strengthened, including the promotion of schistosomiasis prevention and control capacity, establishment of sensitive early-warning surveillance system, and implementation of accurate schistosomiasis prevention and control, in order to consolidate the control achievements and realize the aim of schistosomiasis elimination as soon as possible.
了解四川省血吸虫病防治进展及流行现状，为制定全省血吸虫病消除策略提供依据。
收集2004 - 2015年四川省血吸虫病防治历史资料、防治工作报告、血吸虫病监测数据及防治能力数据，分析全省血吸虫病防治进展及疫情。
四川省11个市有63个血吸虫病流行区，2015年全省达到血吸虫病传播阻断标准。目前，有螺面积2537.54公顷，晚期血吸虫病患者1769例。2004 - 2015年，累计查螺面积433065.80公顷，药物灭螺面积251259公顷。血吸虫病血检2601.7144万人次，化疗789万人次。耕牛查病127.6117万头次。血吸虫病患者、病畜及有螺面积逐年下降。自2010年起无本地感染血吸虫的居民和家畜，自2004年起无感染血吸虫的钉螺。但部分地区专业人员少，技术和硬件落后，血吸虫病防治能力薄弱。
四川省2015年达到血吸虫病传播阻断标准。今后仍应强化血吸虫病综合防治策略，包括提升防治能力、建立灵敏的预警监测体系、实施精准防治，以巩固防治成果，尽快实现消除血吸虫病目标。
