Progress Toward Poliovirus Containment Implementation - Worldwide, 2018-2019. MMWR Morb Mortal Wkly Rep. 2019 Sep 27;68(38):825-829 Authors: Moffett DB, Llewellyn A, Singh H, Saxentoff E, Partridge J, Iakovenko M, Roesel S, Asghar H, Baig N, Grabovac V, Gurung S, Gumede-Moeletsi N, Barnor J, Theo A, Rey-Benito G, Villalobos A, Boualam L, Swan J, Sutter RW, Pandel E, Wassilak S, Oberste MS, Lewis I, Zaffran M, MEng Abstract Among the three wild poliovirus (WPV) types, type 2 (WPV2) was declared eradicated globally by the Global Commission for the Certification of Poliomyelitis Eradication (GCC) in 2015. Subsequently, in 2016, a global withdrawal of Sabin type 2 oral poliovirus vaccine (OPV2) from routine use, through a synchronized switch from the trivalent formulation of oral poliovirus vaccine (tOPV, containing vaccine virus types 1, 2, and 3) to the bivalent form (bOPV, containing types 1 and 3), was implemented. WPV type 3 (WPV3), last detected in 2012 (1), will possibly be declared eradicated in late 2019.* To ensure that polioviruses are not reintroduced to the human population after eradication, World Health Organization (WHO) Member States committed in 2015 to containing all polioviruses in poliovirus-essential facilities (PEFs) that are certified to meet stringent containment criteria; implementation of containment activities began that year for facilities retaining type 2 polioviruses (PV2), including type 2 oral poliovirus ...
