长江中下游的江湖洲滩冬陆夏水，植被茂盛，适宜钉螺孽生，季节性水位起落，钉螺随水扩散蔓延，每年都有大批急性血吸虫感染发生。在总结经验教训，面对新的情况，因地制宜地采取多元化的对策是可取的。为此，我们于１９９２年初选择世业乡南滩，开展了血防综合治理试点工作。 In the middle and lower reaches of the Yangtze River, the rivers and lakes in winter are planted in the winter, with lush vegetation and luxuriant vegetation, which are suitable for snails, seasonal water level rise and fall, snail spread with the spread of water every year, a large number of acute schistosomiasis occurs. In summing up experience and lessons and facing the new situation, it is advisable to adopt a diversified response according to local conditions. To this end, we chose Shiye Township South Beach in early 1992 to carry out the pilot work on comprehensive prevention and control of schistosomiasis.
