Australia monitors its polio-free status by conducting surveillance for cases of AFP in children less than 15 years of age, as recommended by the WHO. Cases of AFP in children are notified to the Australian Paediatric Surveillance Unit or the Paediatric Active Enhanced Disease Surveillance System and faecal specimens are referred for virological investigation to the National Enterovirus Reference Laboratory. In 2018, no cases of poliomyelitis were reported from clinical surveillance and Australia reported 1.24 non-polio AFP cases per 100,000 children, meeting the WHO performance criterion for a sensitive surveillance system. Several non-polio enteroviruses, coxsackievirus A4, coxsackievirus B1, echovirus 9, echovirus 30, enterovirus D68 and enterovirus A71, were identified from clinical specimens collected from AFP cases. Australia also performs enterovirus and environmental surveillance to complement the clinical system focussed on children. In 2018, 33 cases of wild polio were reported with three countries remaining endemic: Afghanistan, Nigeria and Pakistan.
