Circulating vaccine-derived poliovirus (cVDPV2) in Sudan — 4 confirmed AFP (acute flaccid paralysis) cases reported since the start of 2026, per the GPEI Global Polio Update (WHO HQ data as of 18 August 2026). Most recent case onset: 10 June 2026. This week's update flags 3 newly reported AFP case(s) in Gezira, North Kordofan and Red Sea. No African cVDPV activity was previously recorded in this database: this line closes a coverage gap identified via GPEI's own public update page, which HealthWatch Global already cited for Afghanistan and Pakistan without extracting the accompanying African country data.
