2010-2014年丹阳市人群血吸虫病监测及费用分析

目的 探索和评价血吸虫病传播阻断有螺地区人群传染源监测方法，并对所产生的费用进行评估。方法 2010-2014年采用主动监测和被动监测两种方法，连续观察人群病情变化情况，评估两种监测方法的费用。 结果 2010-2014年全市累计血检49 277人，发现阳性608例，血检阳性率为1.23%，未检出病原学阳性病例。主动监测和被动监测血检阳性率分别为1.61%、1.13%，差异有统计学意义（χ2]= 15.982，P < 0.05）。在不考虑组织动员和人工费用的前提下，每查治1例血检阳性者的平均费用，被动监测低于主动监测。结论 作为血吸虫病传播阻断有螺无病地区，在今后传染源监测工作中应采取主动监测与被动监测相结合的方式。

Schistosomiasis monitoring and its cost in population in Danyang City, 2010-2014

Objective To explore the monitoring method of the infection source of schistosomiasis in the population of the schistosomiasis transmission?interrupted area with Oncomelania hupensis snails. Methods The changes of schistosomiasis among the population were investigated by using the active and passive monitoring methods in Danyang City from 2010 to 2014， and the cost?effectiveness of the two monitoring methods was evaluated. Results Totally 49 277 persons were detected for schistosomiasis by dipstick dye immunoassay （DDIA） from 2010 to 2014 and 608 cases were positive， and the positive rate was 1.23%. There were no positive persons by etiology detections. The positive rates of active and passive monitoring methods were 1.61% and 1.13%， respectively and there was a significant difference between them （χ2]= 15.982， P < 0.05）. The average cost per positive case of the active monitoring was higher than that of the passive monitoring without considering the costs of the mobilization and labor. Conclusion In the schistosomiasis transmission?interrupted area with snails， the active and passive monitoring methods need to be combined in the future.
