摘　　要：目的连续系统监测四川省不同地区血吸虫病疫情变化,为制定防治策略提供科学依据。方法2000-2019年期间,在四川省平坝、丘陵和大山区3种亚型地区选取血吸虫病流行村,连续系统开展人畜血吸虫病病情、螺情监测工作。结果选取了广汉市、丹棱县和西昌市开展监测工作,全省3个监测点钉螺面积及查出有螺面积比例总体呈现减少态势,活螺密度从0.91只/0.11 m^2降至0.14只/0.11 m^2,2005年以后未发现感染性钉螺。3个检测点人群感染率从2000年的17.12%下降到2011年的0.17%,此后各年度未发现血吸虫病人。耕牛感染率从2000年9.93%下降到2005年的2.48%,2006年以后无病牛发现。结论2000-2019年四川省重疫区血吸虫病疫情持续下降,病情稳定,但有螺面积比例还较大,建议防止钉螺扩散和严防传染源的输入。Objective To systematically and continuously monitor changes of schistosomiasis epidemics in different areas of Sichuan Province so as to provide scientific basis for formulating control strategies.Methods During 2000-2019,schistosomiasis endemic villages in three subtypes of Plain,Hills,and Mountainous areas in Sichuan Province were selected.Continuous and systematic monitoring of human and animal schistosomiasis and snail epidemic situation was conducted.Results Guanghan,Danling and Xichang were selected for the epidemic surveillance.The area of oncomelania snails and the proportion of areas detected oncomelania snails showed a decreasing trend at three monitoring points.The density of living snails ranged from 0.91/0.11 m^2 to 0.14/0.11 m^2.No infectious oncomelania was found after 2005.The population infection rate in three sites decreased from 17.12%in 2000 to 0.17%in 2011.No schistosomiasis patients were found in the following years.The cattle infection rate dropped from 9.93%in 2000 to 2.48%in 2005,and no cattle were infected after 2006.Conclusion The prevalence of schistosomiasis has continued to decline from 2000 to 2019 in Sichuan Province,and the disease is stable,but the proportion of snail areas is still relatively large.It is recommended to prevent the spread of snails and prevent the input of schistosoma infection.
