目的观察化疗措施控制湖区血吸虫病的长期效果。方法以湖沼地区８个不同类型的血吸虫病流行区实施以化疗为主的防治措施，观察人群病情和草洲螺情的变化。结果连续９年的观察显示，湖区洲岛型超重疫区化疗措施可使居民感染率从３Ｏ％以上降至１５％左右：流行严重的垸内水网型疫区，可使居民感染率从２０％降至１０％左右：洲垸型疫区居民感染率从１５％左右控制在１０％以下。１９９６、１９９７年洪涝灾害后出现了血吸虫感染率的反弹、灾后次年，血吸虫感染率有缓慢的下降。结论化疗措施可以降低居民血吸虫感染率、感染度．不失为湖区血吸虫病病情控制的有效方法。虽然化疗措施可将病情控制在一定水平，但化疗措施仍无法阻断血吸虫病的传播。
Objective To observe the long-term effects of chemotherapy in controlling schistosomiasis in the lake. Methods To control the prevalence of schistosomiasis in eight different types of schistosomiasis endemic areas in lakes and mountains, and to observe the changes of the population and the status of the turf snail. Results Nine consecutive years of observation showed that the infection rate of residents living in the island-type of pandemic outbreaks in the lake area could be reduced from over 30% to over 15%: the most prevalent epidemic area in the embankment could reduce the infection rate from 20 % Down to about 10%: continent embankment type infected area residents infected rate controlled at about 15% below 10%. In 1996 and 1997, there was a rebound in the infection rate of schistosomiasis after floods and floods. After the disaster the following year, the infection rate of schistosomiasis decreased slowly. Conclusion Chemotherapy can reduce the infection rate and infection rate of residents. After all, an effective method for controlling schistosomiasis in the lake area. Although chemotherapy can control the disease to a certain level, chemotherapy still can not stop the spread of schistosomiasis.
