Poliomyelitis, also known as polio, is a highly contagious disease which is caused by a poliovirus that attacks the nervous system. Children younger than 5 years old are more likely to contract the virus than any other groups.
There are two kinds of poliomyelitis: non-paralytic polio and paralytic polio. Symptoms of non-paralytic polio can last from 1 to 10 days, which are sore throat, headache, vomiting, fatigue, meningitis, etc.
Symptoms of paralytic polio are severe spasms, muscle pain, deformed limbs, loss of reflexes, loose and floppy limbs on just one side of the body, etc.
It is estimated that most people who have contracted poliovirus are asymptomatic. However, even without symptoms, people infected with poliovirus can still spread the virus and cause infection in others.
