本文对１２个县（市）的１９个流行村６３８０人进行了ＣＯＰＴ检测，并对检测人群进行了体征调查。结果：人群ＣＯＰＴ阳性率为４７５％，肝右叶、肝左叶、脾脏肿大的百分率分别为７０５％、９７５％和２４０％；进一步分析显示：ＣＯＰＴ阳性人群肝、脾肿大的百分率明显高于ＣＯＰＴ阴性人群（Ｐ均＜００５）。结果表明：在低度流行地区人群的体征，可作为评价血吸虫病防治效果的候选指标之一。对２４个县的４４个流行村晚期血吸虫病调查显示：江苏省晚期血吸虫病患病率已降到００７％，以巨脾型患者最多，占病例的８０％，且未控制地区和基本消灭地区，江滩、山区和水网三种不同类型地区晚期血吸虫病患病率之间无显著差异（Ｐ均＞００５）。表明：江苏省晚期血吸虫病病情稳定，并呈逐渐下降态势 In this paper, 6,380 people from 19 popular villages in 12 counties (cities) were tested for COPT, and physical examinations were performed on the tested population.

Further analysis showed that: , The percentage of splenomegaly was significantly higher than that of COPT negative (P <005).
