In 2025, despite funding cuts and operational challenges, polio environmental surveillance across the African Region demonstrated remarkable resilience and strategic adaptation. With over 500 active surveillance sites, environmental sampling accounted for 56% of poliovirus detections, and in four countries, it was the only source of outbreak detection.
Key optimization efforts, including field missions, capacity building in 16 high-priority countries, and integration with multipathogen surveillance initiatives, strengthened early detection systems.
Performance indicators show strong laboratory quality metrics, while highlighting areas requiring targeted improvement to meet global standards.
