SL1 Sabin-like poliovirus type 1, SL2 Sabin-like poliovirus type 2, SL3 Sabin-like poliovirus type 3, BMFS bag-mediated filtration system, WHO (World Health Organization) algorithm virus isolation on L20B and RD (human rhabdomyosarcoma) cells followed by ITD (intratypic differentiation), Concordant positive method sequentially collected BMFS sample results combined by considering discordant poliovirus results to be negative and by considering concordant poliovirus results as a single sample
