Please report any child less than 15 years of age with acute flaccid paralysis (AFP) in one or more limbs or acute onset of bulbar paralysis.
All cases are reviewed by the Polio Expert Panel and classified as: confirmed poliomyelitis; non-polio AFP; polio compatible or non-AFP.

It is important that stool specimens are collected from all patients with AFP, even when an alternative definitive diagnosis has been confirmed.

Please collect 2 stool samples, more than 24 hours apart and within 2 weeks of onset of paralysis and send them to your local laboratory who will forward them to the National Enterovirus Reference Laboratory, VIDRL, Doherty Institute, 792 Elizabeth Street Melbourne VIC 3000.

On the request form the patient must be identified as having AFP.

Please inform the laboratory that the specimens must be forwarded to VIDRL for exclusion of poliovirus.

All costs for transport and analysis will be borne by VIDRL.
Information regarding specimen transport can be obtained from the National Enterovirus Reference Laboratory at VIDRL on (03) 9342 9607 or https://www.vidrl.org.au/laboratories/poliovirus-reference/specimen-referral/
