摘要 目的了解健康人群肠道病毒携带状况,探讨健康人群肠道病毒携带率与手足口病传播的关系及危害。方法 2011—2012年采集健康人群粪便标本500份。粪便提取核酸后应用实时荧光RT-PCR技术检测人肠道病毒(HEV)、肠道病毒71型(EV71)和柯萨奇病毒A16型(CA16),按照年龄、职业、季节分别进行带毒情况分析。结果 500份标本中,HEV通用引物阳性57份(11.40%),其中EV71、CA16和其他肠道病毒阳性标本分别为9份(1.80%)、7份(1.40%)和41份(8.20%)。各个年龄段肠道病毒携带率差异无统计学意义(P>0.05)。医生、幼儿园工作人员和其他人群的EV71、CA16及其他肠道病毒携带率差异有统计学意义(P<0.05)。按月份分布来看,检出EV71和CA16的标本75.00%分布在5—9月份,检出其他肠道病毒的标本48.78%分布在11月—次年1月份。结论健康人群中肠道病毒携毒率相对较高,EV71和CA16的检出季节分布与手足口病发病的季节分布吻合;医生和幼儿园工作人员等人群病毒携带率较普通人群高,其在手足口病的传播中可能具有重要作用。
