四川省血吸虫病达到传播控制和阻断标准地区流行现状

Current Situation of Schistosomiasis in Transmission Control and Interrupted Areas of Sichuan

目的了解全省血吸虫病达到传播控制和传播阻断标准地区流行现状。方法分层随机抽样调查 2 0 %的流行村的居民、耕牛和钉螺。结果 :全省达到传播控制和阻断标准分别为 2 1个县和 2 5个县。传播控制区疫情大幅度回升 ,2 0 0 1年钉螺面积、急血、病人、病牛和感染钉螺分别占全省的 2 8.6 6 %、32 .0 8%、9.13%、17.5 4 %和 4 5 .98% ;传播阻断地区无病人、病牛和感染钉螺发生 ,但是其中 14个县仍残存钉螺 76 .4万m2 。结论传播控制区各级政府应加大血防经费投入 ,加强疾病监测力度 ,作到疫情早发现 ,早控制 ,尽快控制急性血吸虫病连续发生的势头。传播阻断区必须充分认识到血防的长期性、复杂性和艰巨性。坚持搞好监测巩固工作 ,减少残存螺面 ,防止传染源输入和钉螺扩散。

Objective To master current prevalence situation of schistosomiasis in transmission control and interrupted areas of Sichuan. Method Stratified random samples of villagers, cattle and snail in 20% original endemic villages were surveyed. Results 21 and 25 counties were classified as transmission control and interrupted counties. In transmission control areas, there was a big increase in prevalence situation and the snail habitat area, acute cases, infected human, cattle, and snail accounted for 28.66%, 32.08%, 9.13%, 17.54% and 45.98% respectively of the total of Sichuan in 2001. In transmission interrupted areas, no infected human, cattle and snail were detected out but there were 0.764 million m 2 of residue snail habitat areas in 14 counties. Conclusion It has been suggested by the authors that in transmission control areas,schistosomiasis control invastment should be increased, disease surveillance be strengthened so as to control the acute cases. In transmission interrupted areas, the surveillance and consolidation activities should be sustained and the residue snail areas be decreased and infectious reservoir and snail expantion be controlled.
