Enteroviruses (EVs) are RNA viruses that can cause many clinical syndromes including acute flaccid paralysis (AFP). Within the global polio laboratory network, EVs are categorized either as polioviruses or non-polio enteroviruses (NPEVs). Specific NPEVs have been described in polio-like residual paralytic events in AFP patients. Retrospective analysis of 112 NPEV isolates from AFP patients was performed and thirty one NPEV types were identified of which 91% were Enterovirus B and 9% were Enterovirus A species. The NPEVs were distributed across the country with most patients in the eastern region (41/89; 46.1%). The highest proportion of patients were children less than 5 years (77/89; 86.5%) and male patients were more common (54/89; 60.7%). Echovirus 11 (11/89; 12.4%) was frequently observed and phylogenetic analysis of these sequences revealed high diversity. Coxsackievirus B5 (CV-B5), CV-B6, E21, and EV-B69 were only seen in patients with residual paralysis. Analyses of the EV-A71 sequence indicated a unique genogroup.
肠道病毒（EVs）是一种 RNA 病毒，可以引起多种临床综合征，包括急性弛缓性麻痹（AFP）。在全球脊髓灰质炎实验室网络中，EVs 分为脊髓灰质炎病毒或非脊髓灰质炎肠道病毒（NPEV）。在 AFP 患者类似脊灰的残留麻痹事件中，已经描述了特定的 NPEV。对 112 例 AFP 患者的 NPEV 分离株进行了回顾性分析，鉴定出 31 种 NPEV 型，其中 91%为肠道病毒 B 型，9%为肠道病毒 A 型。这些 NPEV 分布在全国各地，大多数患者在东部地区（41/89；46.1%）。患者中比例最高的是 5 岁以下的儿童（77/89；86.5%），男性患者更为常见（54/89；60.7%）。经常观察到肠道病毒 11 型（11/89；12.4%），这些序列的系统发育分析显示出高度多样性。柯萨奇病毒 B5（CV-B5）、CV-B6、E21 和 EV-B69 仅见于残留麻痹的患者。对 EV-A71 序列的分析表明存在一个独特的基因群。
