PV1 to -3, poliovirus serotypes 1 to 3.
VDPV, vaccine-derived poliovirus; WEAF-B1, West Africa B1 genotype; SOAS, South Asia genotype; iVDPV2, immunodeficient vaccine-derived poliovirus (16 iVDPV2 virus isolates were used for assaying PV2 rRT-PCR only); WPV AFR, wild poliovirus African genotype; WPV SOAS, wild poliovirus South Asia genotype. IPV isolates of serotype 1 (Mahoney) and serotype 3 (Saukett) were positive in both EV and PanPV assays. The Mahoney strain was positive in the Sabin 1 assay and Saukett in the Sabin 3 assay (data not shown).
NPEV, nonpolio enterovirus, including coxsackievirus A4 (CV-A4), CV-A9, CV-A21, CV-B4, and CV-B5, echovirus 6 (E-6), E-9, E-11 (n = 2), and E-12, enterovirus A71 (EV-A71), EV-D68, and EV/rhinovirus, rhinovirus A47, and unknown NPEV (n = 1).
