目的了解芦山县在血吸虫病传播控制达标后的血吸虫病流行现状。方法对芦山县三个村5岁以上的居住人群和所有耕牛部分狗进行血清流行病学调查,采取问卷调查血阳者疫水接触、既往病史、主诉症状和体征,开展钉螺调查。所有数据使用SPSS17.0分析。结果对4524人采血做ELISA检测,血检血阳者197人,血检阳性率4.36%,未发现粪检阳性病人;对12头家畜采血做金标法检测,血检阳性家畜为0,家畜血检阳性率0,未发现粪检阳性家畜。问卷调查血阳者179人,其中92.18%年内有疫水接触史,62.01%患过血吸虫病,67.60%接受过治疗,主要主诉症状和体征出现率为腹痛(53.63%)、腹胀(29.05%)、食欲减退(18.44%)、乏力(16.76%)、肝区痛(14.53%)、腹泻(11.17%)。对总面积6320m2的三个调查点在春秋季开展螺情调查共2次,平均活螺密度为0.52/0.02只/0.1m2,压碎法共解剖340只活钉螺,均未发现有感染性钉螺。结论芦山县血控达标后的防治工作成效稳固,血吸虫病疫情得到有效控制,同时应加强对人群血检阳性者和螺情的监测力度。
Objective To understand the prevalence of schistosomiasis after controlling for the spread of schistosomiasis in Lushan County. Methods Seroepidemiological investigation was conducted on the population of over 5-year-olds and all cattle in three villages of Lushan County.

A total of 6320m2 of the three survey points in the spring and autumn to carry out a total of 2 spiral surveys, the average live density of 0.52 / 0.02 /0.1m2, crushing total of 340 live snails were dissected, did not find infected snails . Conclusion The results of the prevention and treatment work after the blood control reached its standard in Lushan County are stable. The epidemic situation of schistosomiasis has been effectively controlled. At the same time, efforts should be made to monitor the blood test positives and snails.
