WHO Confirms Five African Countries Have Ended Poliovirus Type 2 Outbreaks

The WHO Regional Office for Africa confirmed in August 2026 the closure of poliovirus type 2 outbreaks in five countries - Burundi, Ghana, Guinea-Bissau, the Republic of the Congo and Uganda - after an Independent Outbreak Response Assessment (OBRA) conducted between January and June 2026. The OBRA reviewed surveillance systems, laboratory evidence, epidemiological data, population immunity and vaccination campaign performance. Burundi's outbreak dated to March 2023, the Republic of the Congo's last detection to December 2023 and Uganda's to May 2024, while Guinea-Bissau has reported none since July 2021. Africa was certified free of wild poliovirus in 2020, so these were vaccine-derived type 2 outbreaks.
