A surveillance system has been put in place in the Zhejiang province since achieving there the criteria for transmission interruption of schistosomiasis japonica. Suspected patients and special high-risk groups (e.g. the so called 'floating population' and children under 14 years of age) are screened for Schistosoma japonicum using serological tests. Those with positive serological result are subjected to faecal examination and if S. japonicum eggs are found they are treated with praziquantel and followed by regular re-examination until complete cure, i.e. absence of S. japonicum eggs in faecal samples. Patients with advanced schistosomiasis japonica are continuously followed-up. Implementation of the surveillance system from 1995 to 2002 detected two S. japonicum-infected persons; one came from Anhui province and the other from Jiangsu province, but no new infection occurred among local residents. The number of patients with advanced schistosomiasis japonica decreased from 1524 in 1995 to 906 by the end of 2002; a reduction of 40.6%. However, post-transmission schistosomiasis still continues to weigh on the medial resources. We conclude that the surveillance system in Zhejiang province is effective and a useful means for monitoring the endemic situation of schistosomiasis. Hence, it is recommended to be pursued in the years to come.
自浙江省达到日本血吸虫病传播阻断标准以来，已建立了监测系统。使用血清学检测对疑似患者和特殊高危人群（如所谓的“流动人口”和14岁以下儿童）进行日本血吸虫筛查。血清学检测结果呈阳性者接受粪便检查，若发现日本血吸虫卵，则用吡喹酮治疗，随后定期复查，直至完全治愈，即粪便样本中无日本血吸虫卵。晚期日本血吸虫病患者持续接受随访。1995年至2002年实施监测系统期间，共检测出2例日本血吸虫感染者；1例来自安徽省，另1例来自江苏省，但当地居民中未出现新的感染病例。晚期日本血吸虫病患者数量从1995年的1524例降至2002年底的906例，减少了40.6%。然而，传播阻断后的血吸虫病仍然给医疗资源带来压力。我们得出结论，浙江省的监测系统是有效的，是监测血吸虫病流行情况的有用手段。因此，建议在未来几年继续推行。
