目的：考核与评价广西在基本消灭血吸虫病后监测钉螺措施的效果。方法：在清查疫区残存钉螺的同时，扩大对疫区县的非流行乡村和非流行县螺情调查结合抽查考核。结果：在原疫区及其外围查螺２００５７１１３９ｍ２，在原疫区发现残存螺点１３个，面积２０２６ｍ２，但未发现阳性钉螺。自１９９３年起已连续３年未发现钉螺。在环绕疫区的非流行县——平南和马山系统抽查了３８个乡村，查螺面积１８５５３６ｍ２，均未发现钉螺。结论：表明全区血吸虫病流行地区钉螺基本控制，巩固了血防成果。
Objective: To evaluate and evaluate the effect of monitoring snails in Guangxi after basically eliminating schistosomiasis. Methods: While checking the surviving snails in the affected areas, we expanded the investigation of non-endemic villages and the non-endemic counties in the epidemic-affected counties in combination with spot checks. Results: In the original endemic area and its surroundings, Zhaolou 200571139m2, there were 13 remaining snails found in the original endemic area with an area of 2026m2, but no positive snails were found. Snail has not been found for three consecutive years since 1993. In the non-endemic counties surrounding the epidemic area, Pingnan and Mashan, 38 villages were inspected, with an area of 185,536 square meters of snails. No snails were found. Conclusion: This indicates that the snail control in the endemic areas of schistosomiasis in the whole area has consolidated the results of blood-armor prevention.
