湖北省4个达到消灭血吸虫病标准的江滩流行县1996年底全部出现螺情复燃，继而出现阳性螺，内源性急性血吸虫感染病人。复燃原因主要是通过江水漂浮成为上游螺源接受地，钉螺漏查，引种芦苇及常规灭螺效果不易巩固等。复燃特点符合长江上游戏江对岸有螺源地，江水变缓或江滩延伸，江滩环境复杂等。汛期江水淹没江滩是造成钉螺扩散的主要条件。夕对原因，提出了防制对策措施的建议。
Four endemic counties in Hubei Province, which reached the standard of eradicating schistosomiasis, all reappeared at the end of 1996, followed by positive snails and endogenous acute schistosomiasis. The reason for the resurgence is mainly due to the floating of the river to become the upstream screw source, the snail leakage inspection, the introduction of reeds and the conventional snail killing effect are not easy to consolidate. Rejuvenation features in line with the Yangtze River on the other side of the Spiraea glacier, slowing the river or stretches of rivers and lakes, riverside complex environment. The flooding of river banks in the flood season is the main condition that causes the snail to spread. On the etiology, we put forward some suggestions on prevention and control measures.
