AFP and poliomyelitis: The aim of PAEDS was to help maintain the annual detection rate of AFP for Australia (the World Health Organization [WHO] target is at least 1 nonpolio AFP case/100,000 children <15 years of age/year), improve stool collection (the WHO target for a polio-free country is 2 stool samples within 14 days of symptom onset for >80% of nonpolio AFP cases), and assist in excluding poliovirus infection.
