*EV, enterovirus; NA, not applicable.
†During phase I, human EV was detected and serotyped by using cell culture.
‡During phase II, human EV was detected by reverse transcription PCR (RT-PCR) and genotyped by sequencing of virus capsid protein (VP) 1 region.
§During phase III, human EV was detected by real-time RT-PCR and genotyped by sequencing of the VP1 region.
