2015–2017年句容市国家级血吸虫病 监测点疫情监测

目的　通过对句容市国家级血吸虫病监测点的疫情监测，了解当地血吸虫病流行现状和防治效果，为制定防治措施提供科学依据。方法　按照《全国血吸虫病监测方案（2014年版）》要求，于2015–2017年对句容市空青村国家级血吸虫病监测点进行螺情和人、畜血吸虫病病情等监测。结果　2015–2017年句容市空青村国家级血吸虫病监测点有螺面积分别为0、0、0.63 hm2，活螺平均密度分别为0、0、0.19只/0.1 m2，未发现血吸虫感染性钉螺；本地居民血检阳性率分别为7.72%、7.45%、3.45%，流动人口血检阳性率分别为4.90%、3.47%、0.97%，未发现血吸虫感染病人和病畜。结论　句容市血吸虫病防治效果明显，但钉螺仍有复现；需进一步加强血吸虫病监测和控制力度，巩固已取得的防治成果。

Surveillance of schistosomiasis in a national surveillance site of Jurong City, 2015–2017

Objective　To understand the endemic situation and control effect of schistosomiasis through the surveillance in a national surveillance site of Jurong City, so as to provide the evidence for formulating the prevention and control measures. Methods　According to the National Schistosomiasis Monitoring Scheme (2014 Edition), the surveillance of schistosome infection in Oncomelania hupensis snails, residents and livestock was performed in the Kongqing Village, a national surveillance site of Jurong City, from 2015 to 2017. Results　The areas with snails were 0, 0, and 0.63 hm2 in 2015, 2016, and 2017 respectively; the average densities of living snails were 0, 0, and 0.19 snails/0.1 m2 in 2015, 2016, and 2017 respectively. No schistosome?infected snails were found. The positive rates of blood tests for schistosomiasis in the local residents were 7.72%, 7.45% and 3.45%, and the positive rates of blood tests in the floating population were 4.90%, 3.47% and 0.97% in 2015, 2016 and 2017, respectively. No positives were found in the schistosome etiology detection in the crowd and livestock. Conclusions　The effect of schistosomiasis prevention and control is obvious in Jurong City, but O. hupensis snails are still of recurrence. Therefore, the monitoring and control efforts should be strengthened to consolidate the achievements of schistosomiasis prevention and control.
