贵阳市自1955年建立传染病报告制度以来,脊髓灰质炎(下称脊灰)流行最高峰是1963年,发病率为31.0/10万。同年底在儿童中普遍进行脊灰活疫苗免疫以后,取得十分明显的预防效果。1973年发病率0.63/10万,比1963年的病例数下降97.4%。1983年只报告了1例(0.08/10万)。在连续免疫廿余年间,人群免疫状况如何过去未做过系统调查。为此,我们于1986年3月对本市不同年龄组部份人群进行了抗体水平及肠道病毒带毒情况调查,其结果报告如下。
Since the establishment of an infectious disease reporting system in Guiyang in 1955, the highest prevalence of poliomyelitis (hereinafter referred to as polio) was 1963, with an incidence rate of 31.0 per 100 thousand. At the end of the same year, universal immunization of poliovirus in children has achieved a very clear preventive effect. The incidence was 0.63 / 100,000 in 1973, down 97.4% from 1963. Only one case was reported in 1983 (0.08 / 100,000). In the past 20 years of continuous immunization, how the population’s immune status has not been systematically investigated in the past. To this end, we conducted a survey of antibody levels and enterovirus infection in some of the population in different age groups in our city in March 1986 and the results are reported below.
