目前肠道病毒(简称EV)逐渐引起人们的关注,可致一系列临床疾病。还可引起暴发流行感染,尤其是围产期肠道病毒,是引起母婴感染的重要原因。肠道病毒感染根据EV在动物试验和细胞培养中的生长特性,可将EV归于4大类,即3型脊髓灰质炎病毒(pV),24型C_(ox)AV,6型C_(ox)BV和34型EchoV。目前又发现大量新株型,统称为新肠道病毒。EV感染后,可引起两次程度不同的病毒血症。扩散到靶器官如横纹肌、神经组织,
The current intestinal virus (referred to as EV) has gradually attracted people’s attention, can cause a series of clinical diseases. Can also cause outbreaks of epidemic infections, especially perinatal enterovirus, is an important cause of maternal and infant infections. Enterovirus infection According to the growth characteristics of EV in animal experiments and cell culture, EVs can be classified into 4 groups, namely poliovirus type 3 (pV), type 24 Cox (ox) AV, type 6 Cox (ox) BV and EchoV 34. Now found a large number of new plant types, collectively referred to as the new enterovirus. EV infection can cause two different levels of viremia.
