A Vaccine Preventable Illness
What is poliomyelitis?
History of Polio
Signs and Symptoms of Polio
- Sore throat
- Stomach pain
These symptoms last 2-5 days and then go away on their own.
When poliovirus affects the brain or spinal cord, the following more serious symptoms occur:
- Feeling of pins and needles in the legs
- Meningitis (1 in 25 will experience this infection of the covering of the spinal cord and/or brain)
- Paralysis (1 in 200 people affected) if paralysis of the muscles that allow a person to breathe occurs, death will follow
Transmission of Polio
Complications of Polio
Post-polio syndrome can occur in those originally infected with poliovirus, with paralysis and muscle weakness up to 40 years after the initial infection.
Control Measures for Polio
About 99 out of 100 children who get the four recommended doses of the vaccine are protected from polio.
The Unites States has been polio free for over 30 years, but poliovirus is still seen globally.
Around the world, efforts are being made to eradicate polio. In 1988, some 350,000 cases of infection by polio were seen, down to 402 in 2013. That is a 99% decrease!
