摘　　要：对135例慢性血吸虫病患者进行检测,IHA≥1︰10判为阳性,阳性者再用Kato Katz法或尼龙绢集卵孵化法进行病原学检测,并结合疫水接触史调查,每年剔除观察对象中的再感染者。结果第4年转阴率为93.65%。血吸虫病连续监测过程中,IHA检测人群抗体水平可作为判定疫情是否出现反弹的重要指标之一。A total of 135 chronic schistosomiasis patients were investigated with indirect hemagglutination assay（IHA） kit for schistosomiasis issued by the national authority,and the titer ≥1︰10 was deemed as positive.The IHA positive patients were investigated with Kato-Katz technique and the hatching method,and the water contact survey was performed every year and the re-infection patients were excluded.In the fourth year,93.65%o of the patients became IHA negative.In conclusion,the schistosome antibody levels of the population by IHA test can be one of important indexes to judge whether the epidemic situation relapses in the process of continuous schistosomiasis surveillance.
