摘　　要：目的了解云南省楚雄市血吸虫病传播阻断后疫情趋势，评估防治效果。方法收集楚雄市1994—2012年血吸虫病疫情资料，分析人畜病情和螺情的变化，比较逐年血吸虫病疫情指标变化趋势。结果楚雄市1993年达到血吸虫病传播阻断标准后，无新感染血吸虫病患者、病畜和感染性钉螺发现，活螺密度明显下降，分别由1994年的0．69只／0．1m。降至2012年0．0075只／0．1m22；但钉螺面积回升，有螺面积在2．45—28．04hm2，最严重时出现在2004年和2005年，2012年仍有钉螺面积6．17hm2。结论楚雄市达血吸虫病传播阻断标准后病情稳定，但螺情形势严峻，今后应加大外来传染源监测和钉螺控制力度，以巩固防治成果。Objective To study the epidemic trend in Chuxiong city of schistosomiasis after transmission bloc- king, and to evaluate the control effect. Methods Epidemic data of schistosomiasis in Chuxiong city during 1994 - 2012 were collected, and the annual change trend indicators of schistosomiasis was compared. Re- suits After achieved the blocking standards of schistosomiasis transmission in 1993, no newly infected pa- tients, livestock or snails were reported; the live snail density decreased from 0. 69/0. 1 m2 in 1994 to 0. 0075/0. 1 m2 in 2012. However, the snails area rebounded with a range of 2.45 - 28.04 hm2, peaked in 2004 - 2005 and remained at 6. 17 hm2 in 2012. Conclusion After achieved the blocking standard, the epidemic situation of schistosomiasis stayed stable, yet the snail situation is still severe and thus surveillance on imported infection source and control on oncomelania should be both strengthened to consolidate the achievements.
