我省鄱阳湖区是血吸虫病重流行区,也是全国血防工作难点之一。由于现有灭螺方法的局限性,目前尚不可能消灭如此广阔草洲的钉螺,以至血吸虫病的流行远未得到控制,疫情仍较严重。为寻找湖区经济、有效的血防新对策,我们于1983年初至1985年初在余干县晚湖地区采用化疗对策,即使用吡喹酮普治上晚湖草洲的人群和牛、猪等动物宿主,以期切断传染源,控制血吸虫病流行。经过两年纵向观察,疫情基本得到控制。本文就晚湖试点情况予以描述和分析。
Poyang Lake in our province is endemic area of schistosomiasis, but also one of the difficulties of national blood work. Owing to the limitations of the existing methods for controlling snails, it is not possible to eliminate the snails on such a broad grassland so far that the epidemic of schistosomiasis is far beyond control and the epidemic is still serious. In order to find a new and effective countermeasure for the economic and effective prevention and treatment of schistosomiasis, we adopted a chemotherapy strategy in the late lake area of Yugan County from early 1983 to early 1985, that is, using praziquantel to treat the population of late lakes and lakes and animal hosts such as cattle and pigs, With a view to cut off the source of infection, control of schistosomiasis epidemic. After two years of longitudinal observation, the epidemic basically got under control. This article describes and analyzes the situation of the pilot in the lake.
