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 epidemiological trend of schistosomiasis and the epidemic situation in Sichuan Province and to provide a scientific basis for the formulation and adjustment of blood-control strategy in this province. Methods According to the national schistosomiasis surveillance program, a national monitoring point was set up in Sichuan Province, and the monitoring of schistosomiasis was carried out continuously in 2005-2009. Results Nine national schistosomiasis surveillance sites were established in Pujiang, Guanghan, Zhongjiang, Fucheng, Dongpo, Danling, Renshou, Xichang and Techang counties (cities and districts) in Sichuan Province. From 2005 to 2009, the total snail snail area decreased from 351 853 m2 to 142 983 m2, and the live snail density decreased from 0.70 /0.11 m2 to 0.33 /0.11 m2. The snail infection rate decreased from 0.06% to 0, and snails were mainly distributed in the canals , Paddy fields and drylands and other environments. In 2005-2009, the positive rate of serum schistosomiasis serogroups decreased from 19.41% to 7.11% at the monitoring sites, and the infection rate of schistosoma in the population decreased from 1.93% to 0.02%. In 2005-2009, the infection rate of domesticated schistosomes decreased from 4.50% to 0.45%. Conclusion The schistosomiasis in Sichuan Province has been controlled at a relatively low level. Monitoring work should be done to strengthen comprehensive management and consolidate blood-disease prevention achievements.
