EV71 infection can lead to severe clinical manifestations and even death. Other EVs, however, generally cause mild symptoms. Thus, early and accurate distinction of EV71 from other EVs for HFMD will offer significant benefits. A one\u2010step, single tube, duplex RT\u2010PCR assay is described in the present study to detect simultaneously EV71 and other EVs. The primers used for the duplex RT\u2010PCR underwent screening and optimization. The detection threshold was 0.001 TCID<jats:sub>50<\/jats:sub>\/ml for EV71 and 0.01 TCID<jats:sub>50<\/jats:sub>\/ml for other EVs. The positive rate of enterovirus detection in 165 clinical samples reached 68.5%, including 46.1% for EV71 and 22.4% for other EVs. Of all the severe HFMD cases, EV71 was responsible for 85.3% cases. The positive rate of EV71 fell markedly by day 8 after onset. In addition, sequencing of EV71 specific amplicons from duplex RT\u2010PCR revealed that C4a was the predominant subgenotype of EV71 circulating in Nanjing, China. The accuracy and reliability of the assay suggest strongly that the one\u2010step, single tube, duplex RT\u2010PCR will be useful for early diagnosis and monitoring of EV71 and other EV infections.
