Endemic region indicators
Non-polio acute flaccid paralysis rates
In endemic regions, to ensure even higher sensitivity of surveillance, at least two cases of non-polio acute flaccid paralysis (AFP) should be detected annually per 100 000 population aged less than 15 years.
Adequate stool collection rates
All acute flaccid paralysis (AFP) cases should have a full clinical and virological investigation with at least 80% of AFP cases having adequate stool specimens collected.
Adequate stool specimens are two stool specimens of sufficient quantity for laboratory analysis, collected at least 24 hours apart, within 14 days after the onset of paralysis, and arriving in the laboratory by reverse cold chain and with proper documentation.
