  • In Poland, a cVDPV2 was isolated from an environmental sample, collected from Warsaw on 22 October.  There is no evidence of local circulation.  Initial analysis suggests it is linked to the cVDPV2 emergence originating in Zamfara, northern Nigeria, which has this year been detected internationally, including recently also in Barcelona, Spain.  Poland has high vaccination coverage, estimated at above 90% with three doses of IPV, both national and in the affected subnational area.
