摘要： 目的  评价2004~2015年南京市预防控制血吸虫病中长期规划效果，为制订下一步血吸虫病防控策略提供参考依据。 方法  收集2004~2015年南京市血吸虫病疫情资料进行统计分析。 结果    2004年以来，全市钉螺面积总体呈现下降趋势。钉螺面积由2004年的4 700.25hm2下降至2015年的    1 713.88hm2，降幅达63.54%。感染性钉螺面积下降显著，2009年至今，南京市均未查到阳性螺点。人群DDIA阳性率由2004年的4.04%降为2015年的0.88%，未发生急感病例。2008年以来未查到粪检阳性病例（2012年除外）2006年以来未查到病畜。截至2015年，全市11个血吸虫病流行区县中7个达到血吸虫病传播阻断标准，4个达到血吸虫病传播控制标准。 结论  通过实施钉螺控制和传染源控制并重的综合防治策略，南京市血吸虫病疫情防控效果显著，顺利完成血吸虫病规划目标。

Abstract:

Objective To evaluate the effectiveness of the medium-and-long-term program of prevention and control of schistosomiasis in Nanjing City from 2004 to 2015, so as to provide evidences for following strategies in prevention and control of schistosomiasis. Methods  The data were collected and statistically analyzed on the endemic schistosomiasis in Nanjing City from 2004 to 2015. Results  Areas with snails tended to decline in general throughout Nanjing after 2004, with a decline rate of 63.54%(decrease to 1 713.88hm2 in 2015 from 4 700.25hm2 in 2004). The decrease of infected snails was significant, and no positive snail habitats were detected in Nanjing area after 2009. Dipstick dye immunoassay(DDIA) indicated that the population infection was dropped to 0.88% in 2015 from 4.04% in 2004, and no acute schistosomiasis occurred in 10 years. There was no positive case by stool examination since 2008(exclusive in 2012), and no livestock infection after 2006. By 2015, seven of 11 administrative counties and districts under Nanjing City reached the criteria for transmission interruption of the schistosomiasis, and 4 counties and districts were up to the criteria of schistosomiasis infection control. Conclusion  The endemic situation in Nanjing City has been effectively controlled through comprehensive measures for control of the snail prevalence and infectious sources, suggesting that the medium-and-long-term program has been well fulfilled.
