The poliovirus invades the nervous system, infecting spinal motor neurons and/or brainstem nuclei. Initial symptoms are fever, fatigue, headache, vomiting, stiffness in the neck and pain in the limbs. Although polio paralysis is the most visible sign of polio infection, fewer than 1% of polio infections ever result in paralysis. Amongst those paralysed, 5%-10% die when their breathing muscles become immobilised. Read more: www.poliohealth.org.au/poliovirus/

Poliomyelitis (polio) is a highly infectious disease caused by a virus. There is no cure for polio, only prevention through vaccination. Polio is primarily spread through the oral-faecal route. Poliovirus enters through the mouth and multiplies in the intestine. People infected with the poliovirus can pass the virus on for 7–10 days before the onset of symptoms. In addition, they can continue to shed the virus in their stools for 3–6 weeks. Polio is still endemic in some countries. Read more: https://www.poliohealth.org.au/poliovirus/
