This is the first report of persistent oropharyngeal mucosal infection with type 2 poliovirus (iVDPV2) in a primary immune deficient patient (PID) after wild type 2 poliovirus eradication. The iVDPV2 also established persistence in the gut. iVDPV2 at both loci evolved independently. Persistent oral infections present a potential risk for oral-oral as well as fecal-oral poliovirus transmission during transition to a poliovirus 2-free world.
这是首例原发性免疫缺陷患者(PID)在野病毒 2 型脊灰(WPV2)根除后发生 2 型脊灰病毒(iVDPV2)持续口咽黏膜感染的报告。该 iVDPV2 也在肠道中持续存在。两个部位的 iVDPV2 均独立进化。在向无脊灰病毒 2 型世界过渡期间,持续的口腔感染可能会增加病毒经口-口及粪-口传播的风险。
