  • Three wild poliovirus type 1 (WPV1) cases were reported from South Sudan this week. Genetic sequencing is underway to determine the origin of the isolated viruses and possible relation to the ongoing Horn of Africa outbreak. The cases are from North Bahr El Gazal state (close to the border to Sudan) and Eastern Equatoria state (close to the border with Kenya and Uganda). The cases have triggered a full outbreak response from the Global Polio Eradication Initiative (GPEI) operational perspective.
