AFP and Paralysis: According to WHO recommendations, there are two main AFP quality indicators: the first is ‘non-polio AFP rate’ which indicates that a sensitive surveillance system should detect at least one case of non-polio AFP each year for every 100,000 children under 15 years of age; the second is ‘adequate stool specimen collection’ which requires that ≥80% of AFP cases have two stool specimens collected 24–48 h apart, both within 14 days of paralysis onset, and that these specimens arrive in good condition at a WHO-accredited laboratory [2,7].
