目的了解广西壮族自治区边境及省界地区,健康人群脊髓灰质炎(脊灰)抗体水平。方法采取多阶段随机抽样方法,从18个边境及省界地区县1～59岁常住人口中抽取902人,采集血清标本,检测脊灰中和抗体。结果脊灰Ⅰ、Ⅱ、Ⅲ型中和抗体阳性率分别是93.90%、97.67%、92.02%;几何平均滴度分别为1:53.22、1:66.51、1:20.01。结论广西壮族自治区边境及省界地区健康人群脊灰抗体水平良好。
Objective To understand the level of poliomyelitis (polio) antibody in healthy population in the border and provincial boundaries of Guangxi Zhuang Autonomous Region. Methods A multistage random sampling method was used to select 902 residents aged from 1 to 59 years old from 18 border areas and provincial districts and counties. Serum samples were collected for detection of neutralizing antibodies against polio. Results The positive rates of neutralizing antibodies of type Ⅰ, Ⅱ and Ⅲ were 93.90%, 97.67% and 92.02%, respectively. The geometric mean titers were 1: 53.22, 1: 66.51 and 1: 20.01, respectively. Conclusions The level of poliovirus in healthy population in border areas and provincial boundaries of Guangxi Zhuang Autonomous Region is good.
