On Monday 7 March 2022, a case of circulating vaccine-derived poliovirus type 3 (cVDPV3) was confirmed in an unvaccinated girl aged three years and nine months in Israel. The girl had developed acute flaccid paralysis and upon testing of her stool, poliovirus was confirmed.
Further testing of the poliovirus isolated from the girl revealed genetic links to VDPV3-strains detected in environmental samples collected from sites in in Israel and the occupied Palestinian territory between September 2021 and January 2022. These isolates, previously classified as ambiguous VDPV3, have now been reclassified as circulating VDPV3 (cVDPV3). This confirms an outbreak of cVDPV3 in both Israel and the occupied Palestinian territory.
In addition, the Israel Ministry of Health reported Thursday (computer translated):
