The quality of AFP surveillance is monitored by 2 key indicators established by the World Health Organization (WHO): sensitivity of reporting (target: non–polio-associated AFP rate of ≥2 cases per 100 000 children aged <15 years) and completeness of stool specimen collection (target: 2 adequate stool specimens from ≥80% of all persons with AFP that are shipped to a WHO-accredited laboratory and arrive in good condition).
