Background:

The STRIDES program (Strengthening Infectious Disease Detection Systems), funded by the U.S. Department of State, supports countries to strengthen surveillance systems critical to global health security and polio eradication. As part of its polio portfolio, STRIDES is supporting efforts to improve the quality and performance of Acute Flaccid Paralysis (AFP) surveillance and environmental surveillance (ES) systems in alignment with Global Polio Eradication Initiative (GPEI) standards.

Despite ongoing partner support, persistent gaps remain in AFP case detection, investigation, specimen collection and transport, ES functionality, reporting pathways, and data quality in select geographic areas. A rapid, multi-partner surveillance system assessment is required to identify root causes of underperformance and inform targeted, evidence-based interventions in priority counties. This assessment will directly support STRIDES’ objective to strengthen surveillance systems and improve early detection of poliovirus transmission.
