Brazzaville, May 14, 2024 – Following thorough assessments in Malawi and Mozambique, an independent Polio Outbreak Response Assessment Team (OBRA) today recommended the closure of the wild poliovirus type 1 (WPV1) outbreak in Malawi and Mozambique, marking a significant milestone in the fight against polio in the African region.

The last WPV1 case in the African Region, linked to a strain circulating in Pakistan, was reported in Mozambique´s Tete Province in August 2022. A total of nine cases were detected in Mozambique and neighbouring Malawi, where the outbreak was declared in February 2022. In a coordinated response, more than 50 million children have been vaccinated to date against the virus in southern Africa.

The meticulous evaluation carried out by the OBRA team included two in-depth field reviews and supplementary data review, concluding that there is no evidence of ongoing wild polio transmission. The assessment considered the quality of the outbreak response, including the overall population immunity, supplementary immunization campaigns, routine immunization coverage, surveillance systems, vaccine management practices, and the level of community engagement.
