Non-paralytic polio: can last from one to 10 days
signs and symptoms can be flu-like and can include:
95 to 99 percent of people who contract polio virus are asymptomatic- this is known as subclinical polio.
Even without symptoms, people infected with poliovirus can still spread the virus and cause infection in others.
One percent of polio cases can develop into paralytic polio.
Paralytic polio leads to :
-paralysis in the spinal cord (spinal polio), brainstem (bulbar polio), both (bulbospinal polio).
Initial symptoms are similar to non-paralytic polio. But after a week, more severe symptoms will appear. These symptoms include:
-loss of reflexes
-severe spasms and muscle pain
-loose and floppy limbs, sometimes on just one side of the body
-sudden paralysis, temporary or permanent
-deformed limbs, especially the hips, ankles, and feet
Post-polio syndrome (PPS)
It’s possible for polio to return even after you’ve recovered. This can occur after 15 to 40 years. Common symptoms of post-polio syndrome (PPS) are:
-continuing muscle and joint weakness
-muscle pain that gets worse
-becoming easily exhausted or fatigued
-muscle wasting, also called muscle atrophy
-trouble breathing and swallowing
-sleep apnea, or sleep-related breathing problems
-low tolerance of cold temperatures
-new onset of weakness in previously uninvolved muscles
-trouble with concentration and memory
