1988年世界卫生大会作出消除脊髓灰质炎(脊灰)的决定后,WHO建立了全球实验室网络,通过检测急性迟缓性麻痹(AFP)病人粪便,对脊灰病毒进行全球监测。本文总结了实验室网络近期的工作情况,描述了2002年1月～2003年6月期间脊灰野毒株(WPVs)和脊灰病毒疫苗株(VDPVs)的定位和特征。
Following the World Health Assembly’s decision to eradicate poliomyelitis (polio) in 1988, WHO established a global network of laboratories to globally monitor poliovirus by detecting faeces from patients with acute delayed paralysis (AFP). This article summarizes recent work on laboratory networks and describes the location and characterization of poliovirus (WPVs) and poliovirus vaccine strains (VDPVs) from January 2002 to June 2003.
