脊髓灰质炎(脊灰)是由脊灰病毒(poliovirus,PV)引起的一种急性传染病,PV侵入血液循环系统,部分PV可侵入神经系统,造成肢体不可逆麻痹甚至死亡[1]。人对PV普遍易感,中国以1~5岁幼儿发病率最高,脊灰的流行严重危害儿童健康。“监测”是消灭脊灰的基本策略,其中包括病例监测、强化免疫和常规免疫监测等。提高整个人群的免疫力对PV可形成免疫屏障,可有效阻断PV的传播。为此,本研究对辽宁省2006—2011年来健康人
Polio (poliomyelitis) is an acute infectious disease caused by poliovirus (PV), which invades the blood circulation and some PV can invade the nervous system, resulting in irreversible paralysis and even death of limbs [1]. People are generally susceptible to PV, the highest incidence of children aged 1 to 5 years in China, the prevalence of polio seriously endangering children’s health. “Monitoring ” is the basic strategy for polio eradication, including case monitoring, intensive immunization and routine immunization surveillance. Improve the immunity of the entire population PV can form an immune barrier, which can effectively block the spread of PV. To this end, this study of healthy people in Liaoning Province from 2006 to 2011
