达到消灭血吸虫病标准的地区,应用粪检法查病,敏感性较差,很难查出低感染度的残存或和新感染者。血清试验检测人群血清抗体的灵敏度显著高于粪检病原。我们应用酶联免疫吸附试验（ELISA）对基本消灭和消灭地区不同人群血清进行血吸虫抗体水平的纵向观察,探讨对可疑的新感染及残存感染者的应用价值。 Achieve the standard of eliminating schistosomiasis in the area, the application of fecal examination disease detection, poor sensitivity, it is difficult to detect residual or low infection and new infections. Serum tests to detect serum antibody sensitivity was significantly higher than the stool pathogen. We used enzyme-linked immunosorbent assay (ELISA) for the longitudinal elimination of schistosoma japonicum antibody levels in different groups of people who were basically eliminated and eliminated, and explored the value of suspicious new infections and residual infection.
