摘要
江陵县用微量凝集试验对1987年、1989年和1990年健康人群血清383份进行副百日咳抗体水平检测,阳性率为55.61%,抗体几何平均滴度(GMT)为1:6.99。1989年和1990年阳性率和 GMT 高于1987年。10岁以下儿童的阳性率(48.89%)及 GMT(1:5.08)最低,10～19岁达高峰。20岁后趋于恒定。研究结果表明,我县不但有副百日咳感染存在,且流行程度不亚于百日咳。
This paper reports the results of a serological investigation of para-pertus- sis infection in 383 sera samples from healthy persons collected from 1984 to 1990 in Jiangiing county by means of the microagglutination test.The positive rate of para-pertussis antibody was 55.61% and the GMT was 1:6.99,both showing a rising tendency for different age groups during the 3-year period.The positive rate (48.89%) and GMT (1:5.08) in children less than ten years of age were the lowest,and the highest rate occurred at the ages of 10-19 years(64.55% and 1:9.11) while at fhe age above 20 years were in the range of 50-56.14% and 1:6.32-7.58 respectively.The results showed that para-pertussis infection is an infectious disease,and its spread is as extensive as pertussis in Tiangling county.
