摘　　要：目的掌握四川省血吸虫病流行趋势和疫情变化规律,为该省制定和调整血防策略提供科学依据。方法按照全国血吸虫病监测方案在四川省设立国家级监测点,2005-2009年连续开展血吸虫病监测工作。结果在四川省的蒲江、广汉、中江、涪城、东坡、丹棱、仁寿、西昌和德昌等县(市、区)设立了9个国家血吸虫病监测点。2005-2009年监测点钉螺总面积从351 853 m2下降到142 983 m2,活螺密度从0.70只/0.11 m2下降到0.33只/0.11 m2,钉螺感染率0.06%下降到0,钉螺主要分布在沟渠、稻田和旱地等环境。2005-2009年监测点人群血清血吸虫抗体阳性率从19.41%下降到7.11%,人群血吸虫感染率从1.93%下降到0.02%。2005-2009年监测点家畜血吸虫感染率从4.50%下降到0.45%。结论四川省血吸虫病已控制在较低水平,应做好监测工作,加强综合治理,巩固血防成果。Objective To understand the epidemic trend of schistosomiasis in Sichuan and provide scientific evidence for the development and revision of schistosomiasis prevention strategy.Methods According to the national schistosomiasis surveillance protocol,the national surveillance sites were selected in Sichuan.The schistosomiasis surveillance was carried on continuously from 2005 to 2009.Results Nine national schistosomiasis surveillance sites were established in Pujiang,Guanghan,Zhongjiang,Fucheng,Dongpo,Danling,Renshou,Xichang and Dechang counties.The snail area declined from 351 853 m^2 in 2005 to 142 983 m^2 in 2009.The snail density declined from 0.70/0.11 m^2 to 0.33/0.11 m^2.The snail infection rate declined from 0.06% to 0.The positive rate of human serum schistosoma antibody declined from 19.41% to 0.45%,and the human schistosoma infection rate declined from 1.93% to 0.02%.The livestock schistosoma infection rate declined from 4.50% to 0.45%.Conclusion The schistosomiasis epidemic remained at low level in Sichuan.To consolidate the schistosomiasis control achievement,the surveillance should be carried out continuously and the comprehensive control measure should be strengthened.
