Polio - The old foe and new challenges: An update for clinicians

Area of Science:

• Virology
• Public Health
• Pediatrics

Background:

• The Global Polio Eradication Initiative (GPEI) has drastically reduced poliovirus impact since 1988.
• Two of three poliovirus strains eradicated in the last five years due to global vaccination and surveillance.
• Poliomyelitis is characterized by acute flaccid paralysis in children.

Purpose of the Study:

• To summarize the progress of the Global Polio Eradication Initiative.
• To highlight Australia's role in polio surveillance.
• To underscore the importance of recognizing non-polio enteroviruses causing polio-like paralysis in children.

Main Methods:

• Review of global polio eradication efforts and surveillance data.
• Description of Australia's contribution through the Australian Paediatric Surveillance Unit and Paediatric Active Enhanced Disease Surveillance Network.
• Emphasis on detecting acute flaccid paralysis in pediatric populations.

Main Results:

• Polio incidence reduced from global epidemics to endemic status in only two countries.
• Successful eradication of two poliovirus strains.
• Australia actively contributes to global surveillance for acute flaccid paralysis.

Conclusions:

• The polio endgame requires continued vigilance.
• Non-polio enteroviruses can cause polio-like paralytic diseases in children.
• Paediatric clinicians need increased awareness of these polio-like illnesses.
