为探索应用血清学方法对达到基本消灭和消灭血吸虫病标准的地区进行监测的可能性,本研究应用COPT对已达到基本消灭标准8～16年的5个试区中6～14周岁的儿童进行连续8年的纵向观察,结果提示,用COPT对低年龄组儿童检测可作为血清学监测的一种可行的方法;各试区低年龄组儿童人群的COPT的阳性率（阳性者指≥1％者）均不超过3％;出现反应者的环沉率均无≥5％者,这二项指标似可作为监测的观察指标。
In order to explore the possibility of using serological methods to monitor the area that basically eliminated and eradicated schistosomiasis, this study applied COPT to children aged 6 to 14 in 5 pilot districts that have reached the standard of 8 to 16 years The longitudinal observation for 8 consecutive years showed that COPT could be used as a feasible method for serological surveillance in children of the lower age group. The positive rate of COPT in the low-age group of children in each experimental group (positive≥1% ) Were not more than 3%; there is no ring reaction rate were ≥ 5%, these two indicators can be used as monitoring indicators.
