Acute flaccid paralysis can be caused by many members of the enterovirus genus, most notably the three poliviruses types 1 to 3. We report the case of acute flaccid paralysis caused by echovirus 19. The Western Pacific region has been declared polio free by the WHO since 2000. Australia is now using inactivated polio vaccine in the National Immunization Schedule. This vaccine does not carry the extremely rare risk of vaccine associated acute flaccid paralysis but it does leave our newly vaccinated population open gastrointestinal infection with polioviruses and the risk of circulation of the wild-type virus. Continued surveillance of cases of acute flaccid paralysis is to detect polioviruses is essential until poliovirus is completely eradicated.
