尽管中国四川省过去几十年在血吸虫病控制方面取得了很大进展，但这种疾病在以前控制的地区重新出现。我们回顾了历史记录，发现到2004年底，血吸虫病在8个县重新出现，2001年报告的21个传播控制县中有7个县和25个传播中断县中有1个县被证实有当地疾病传播。平均“恢复时间”（从控制到重新出现）约为8年。复发的开始通常是由急性感染的发生标志的。我们的调查结果表明，环境和社会政治因素在重新出现中发挥了重要作用。主要的挑战是长期巩固和保持有效的控制，直到实现“真实的”根除。只有制定一个可持续的监督和控制制度，才有可能做到这一点。
Despite great strides in schistosomiasis control over the past several decades in Sichuan Province, China the disease has re-emerged in areas where it was previously controlled. We reviewed historical records and found that schistosomiasis had re-emerged in eight counties by the end of 2004 - seven of 21 counties with transmission control and one of 25 with transmission interruption as reported in 2001 were confirmed to have local disease transmission. The average "return time" (from control to re-emergence) was about eight years. The onset of re-emergence was commonly signalled by the occurrence of acute infections. Our survey results suggest that environmental and sociopolitical factors play an important role in re-emergence. The main challenge would be to consolidate and maintain effective control in the longer term until "real" eradication is achieved. This would be possible only by the formulation of a sustainable surveillance and control system.
