1.报告了1986年我市192名0～15岁的儿童百日咳抗体水平,阳性161人;阳性率为83.85%,抗体平均几何均数为685.44。2.抗体水平年龄越大,抗体阳性越高。3.不同性别之间百日咳的抗体水平无显著性差异数(P>0.05)。4.各年龄组的抗体阳性率与发病构成呈负相关(相关系 r=—0.9460)。抗体阳性率越高发病构成越低。0～5岁年龄组发病构成占69.22%,因此,对低年龄组的儿童加强百日咳的免疫,是预防百日咳发病和流行的重要环节。
1. reported in 1986 in our city 192 children aged 0 to 15 years of age with pertussis antibody levels, 161 were positive; the positive rate was 83.85%, the average geometric mean antibody was 685.44.2. Antibody level the older, the higher the antibody positive . There was no significant difference in antibody levels of pertussis among different sexes (P> 0.05). The antibody positive rate of all age groups was negatively correlated with the incidence of disease (r = -0.9460). The higher the positive rate of antibodies, the lower the incidence of disease. The incidence of onset and prevalence of whooping cough is 69.22% in the age group of 0 ~ 5 years. Therefore, strengthening the immunity of pertussis in children in the lower age group is an important part of prevention and control of the onset and prevalence of pertussis.
