What is polio?
Polio, or poliomyelitis, is a disabling and life-threatening disease caused by the poliovirus. The virus can infect a person’s spinal cord, causing paralysis (can’t move parts of the body). Paralysis caused by poliovirus occurs when the virus replicates in and attacks the nervous system. The paralysis can be lifelong, and it can be deadly.
It most often sickens children younger than 5 years old.
What are the symptoms of polio infection?
Most people who get infected with poliovirus do not have any symptoms. Some people (25 people out of 100) will have flu-like symptoms. These symptoms usually last 2 to 5 days.
In rare cases, poliovirus infection can be very serious. About 1 out of 200 people will have weakness or paralysis in their arms, legs, or both. This paralysis or weakness can last a lifetime.
Is it serious?
The risk of lifelong paralysis is very serious. Even children who seem to fully recover can develop new muscle pain, weakness, or paralysis as adults, 15 to 40 years later.
About 2 to 10 children out of 100 who have paralysis from polio die because the virus affects the muscles that help them breathe.
How does polio spread?
Poliovirus is very contagious. It spreads through contact with:
- the stool (poop) of an infected person.
- droplets from a sneeze or cough of an infected person.
If you get stool or droplets from an infected person on your hands and you touch your mouth, you can get infected. Also, if your child puts objects, like toys, that have stool or droplets on them into their mouth, they can get infected.
An infected person may spread the virus to others immediately before and up to to 2 weeks after symptoms appear.
- The virus may live in an infected person’s stool for many weeks. He or she can contaminate food and water when they touch it with unwashed hands.
- People who don’t have symptoms can still pass the virus to others and make them sick.
Do people still get polio in the United States?
No, thanks to a successful vaccination program, the United States has been polio-free for more than 30 years, but the disease still occurs in other parts of the world. It would only take one person with polio traveling from another country to bring polio back to the United States.
Children who will be traveling to a country where the risk of getting polio is greaterexternal icon should complete the series of shots before leaving for their trip. If a child cannot complete the routine series before leaving, a polio accelerated schedule is recommended.
Follow the vaccine schedule
The Centers for Disease Control and Prevention, American Academy of Family Physicians, and American Academy of Pediatrics strongly recommend children receive all vaccines according to the recommended vaccine schedule.
