目的掌握四川省血吸虫病防治工作进展及疫情现状,为制定消除血吸虫病策略提供参考依据。方法收集2004-2015年四川省血吸虫病历史资料、血吸虫病防治工作报表、血吸虫病监测资料和血防能力资料,分析血吸虫病防治工作进展和流行现状。结果四川省11个市(州)63个县(市、区)流行血吸虫病,2015年全省达到血吸虫病传播阻断标准。全省现有钉螺面积2 537.54 hm2,现有晚期血吸虫病人1 769例。2004-2015年累计查螺433 065.80 hm2,药物灭螺251 259 hm2;人群血检2 601.714 4万人次,人群化疗789万人次;检查耕牛127.611 7万头次。2004-2015年全省血吸虫病人和病畜数、有螺面积逐年下降,自2010年至今未发现当地感染的病人和病畜,自2004年至今未发现感染性钉螺。部分地区血防专业技术人员较少,防治技术与硬件设备落后,血吸虫病防控能力较弱。结论四川省已于2015年达到了血吸虫病传播阻断标准;今后应进一步加强综合治理、提高能力建设、建立敏感有效的监测体系、实施精准血防,从而巩固全省血吸虫病传播阻断成果,力争早日消除血吸虫病。
Objective To master the progress of schistosomiasis control in Sichuan Province and the status quo of epidemic situation, so as to provide a reference for formulating the strategy of eliminating schistosomiasis. Methods The data of schistosomiasis history, schistosomiasis control, schistosomiasis monitoring data and blood-armor ability data from 2004 to 2015 were collected to analyze the progress and prevalence of schistosomiasis control. Results Schistosomiasis was endemic in 63 counties (cities and districts) in 11 cities (prefectures) in Sichuan Province. In 2015, the province reached the standard of blocking schistosomiasis transmission. The province has 2 537.54 hm2 snails and 1 769 advanced schistosomiasis patients. In 2004-2015, there were 433 065.80 hm2 of snail and 251 259 hm2 of snail. The blood test was 2 601.714 and the population of chemotherapy was 789 000. The inspection of cattle was 127.611 70000 times. From 2004 to 2015, the number of schistosomiasis patients and sick animals in the province declined year by year. Since 2010, no infected patients and sick animals have been found. No infectious snails have been found since 2004. In some areas, there are fewer blood-professional technicians, prevention and control technologies and hardware are backward, and schistosomiasis prevention and control is weak. Conclusion Sichuan Province has reached the standard of blocking schistosomiasis transmission in 2015. In the future, we should further strengthen comprehensive management, improve capacity building, establish a sensitive and effective monitoring system, and implement accurate blood-borne diseases so as to consolidate the achievements in the prevention and control of schistosomiasis transmission in the province, As soon as possible to eliminate schistosomiasis.
