Polio initially shows up as mild flu-like symptoms. In a minority of cases, more serious symptoms may appear including muscle pain, muscle weakness and, in extreme cases, paralysis.
Anyone can be infected with the polio virus. 80%-90% of cases appear in children under five years of age.
Polio is diagnosed by testing samples taken from the feces or the throat, and, if necessary, from the fluid around the spinal cord and brain.
Severe polio is treated by supportive treatment, including pain relief and physical therapy.
