摘要：The Australian National Poliovirus Reference Laboratory (NPRL) is accredited by the World Health Organization (WHO) for the testing of stool specimens from cases of acute flaccid paralysis (AFP), a major clinical presentation of poliovirus infection. The NPRL, in collaboration with the Australian Paediatric Surveillance Unit, co-ordinates surveillance for cases of AFP in children in Australia, according to criteria recommended by the WHO. Clinical specimens are referred from AFP cases in children and suspected case of poliomyelitis in persons of any age. The WHO AFP surveillance performance indicator for a polio-free country such as Australia, is 1 non-polio AFP case per 100,000 children less than 15 years of age. In 2008, the Polio Expert Committee (PEC) classified 62 cases as non-polio AFP, or 1.51 non-polio AFP cases per 100,000 children aged less than 15 years. Poliovirus infection is confirmed by virus culture of stool specimens from AFP cases as other conditions that present with acute paralysis can mimic polio. While no poliovirus was reported in Australia from any source in 2008, the non-polio enteroviruses echovirus 25, coxsackievirus B2 and echovirus 11 were isolated from stool specimens of AFP cases. The last report of a wild poliovirus in Australia was due to an importation from Pakistan in 2007. With 4 countries remaining endemic for poliomyelitis– Afghanistan, India, Nigeria and Pakistan–and more than 1,600 confirmed cases of wild poliovirus infection in 18 countries in 2008, Australia continues to be at risk of further importation events.
