WPV1 in Germany

Two wild poliovirus type 1 (WPV1) positive environmental samples have been reported from Hamburg on 7 and 13 October 2025. These samples are from the same collection site as the previously-reported WPV1-positive environmental sample collected on 6 October 2025. The isolates are closely genetically linked. There are no associated cases of paralysis and no evidence of local community transmission. Please see our Topics in Brief article for further details on polio.
