摘要
目的评价2004~2014年湖南省预防控制血吸虫病中长期规划实施效果,为制订下一阶段防治规划提供参考。方法采取以钉螺控制、人畜化疗、健康教育和传染源控制为主的综合防治措施,按照预防控制血吸虫病中长期规划要求的人畜查病和钉螺调查评价防治效果。结果 2004~2014年全省共血检查病761.6万人次,人群化疗507.1万人次,晚期血吸虫病救治3.57万人次。家畜查病127.9万头(只),家畜化疗171.8万头(只)。累计开展查螺88.52亿m2,药物灭螺17.02亿m2。累计封洲禁牧面积12.97亿m2,淘汰家畜8.2万头(只)。至2014年,人群血吸虫感染率降至0.51%,家畜(牛)感染率降至0.40%。全省垸内钉螺面积虽大幅度下降,但全省有螺面积维持在17.50亿m2上下,钉螺和感染性钉螺密度均显著下降。2015年全省以行政村为单位达到传播控制标准,其中15个县达到传播阻断标准,实现了预防控制血吸虫病中长期规划目标。结论实施以传染源控制为主的综合防治策略效果显著。
Objective To evaluate the end- term effectiveness following of medium- long- term program for schistosomiasis control in Hunan Province from 2004 to 2014 for evidence to plan controlling measures in following tasks. Methods Comprehensive measures were carried out in implementation of the program, including snail control, chemotherapy for residents and livestock, health education and control of the in? fectious sources. The end-term effectiveness was evaluated based on the schistosomiasis detection in population and livestock as well as survey on the prevalence status of snails in local area specified in the medium- and long- term program. Results From 2004 to 2014, schistosomiasis detection was given in 7 616 000 persontimes, chemotherapy in 5 071 000 person-times, and treatment in 35 700 individuals of advanced schistosomiasis. A total of 1 279 000 cattle were subjected to detection of the schistosome infection, and 1 718 000 cattle to chemotherapy. Snail survey and use of molluscicide covered an area of 885 200 hm2 and 170 200 hm2, respectively. Marshland isolation and farming prohibition in lake district were practiced in area of 129 700 hm2, and 82 000 livestock were eliminated. By 2014, the infection rate in population and cattle was reduced to 0.51% and 0.40% , respectively. The areas with snails within the embankment across the province were greatly re? duced, yet the areas with snail presence remained approximately 175 000 hm2. The density for living and infect? ed snails was remarkably declined. By 2015, criteria of transmission control, evaluated as individual administra? tive village, achieved across the province, where 15 counties reached the criteria of transmission interruption. Conclusion Hunan province has achieved the goal of schistosomiasis control specified in the medium- longterm program, and the effectiveness appears remarkable as a result of comprehensive measures on infection source control basis.
