Abstract
Israel conducts routine environmental (15 sites) and acute flaccid paralysis (AFP) surveillance for poliovirus. During September 2021, increasing numbers of wastewater samples collected from more than one site in the Jerusalem region proved positive for ambiguous type 3 vaccine-derived poliovirus (aVDPV3), while environmental samples from remaining sampling sites were negative. In late February 2022, a VDPV3, genetically related to the Jerusalem environmental surveillance samples, was isolated from a stool sample collected from a non-immunodeficient, non-immunized child from Jerusalem who developed AFP, indicating that the aVDPV3s were circulating (cVDPV3s) rather than immunodeficiency-related VDPV3s (iVDPVs). In response to these isolations, the Israel Ministry of Health launched a catch-up immunization program.
