Polio

 

 

Overview

Polio is a contagious viral illness that in its most severe form causes nerve injury leading to paralysis, difficulty breathing and sometimes death.

 

In the U.S., the last case of naturally occurring polio was in 1979. Today, despite a worldwide effort to wipe out polio, poliovirus continues to affect children and adults in parts of Asia and Africa.

 

The Centers for Disease Control and Prevention (CDC) advises taking precautions to protect yourself from polio if you're traveling anywhere there's a risk of polio.

 

Adults who have been vaccinated against polio who plan to travel to an area where polio is occurring should receive a booster dose of inactivated

poliovirus vaccine (IPV). Immunity after a booster lasts a lifetime.

 

Symptoms

 

Although polio can cause paralysis and death, the majority of people who are infected with the virus don't get sick and aren't aware they've been infected.

 

Nonparalytic polio

Some people who develop symptoms from the poliovirus contract a type of polio that doesn't lead to paralysis (abortive polio). This usually causes the same mild, flu-like signs and symptoms typical of other viral illnesses.

 

Signs and symptoms of nonparalytic polio which can last up to 10 days, include:

 

Fever

Sore throat

Headache

Vomiting

Fatigue

Back pain or stiffness

Neck pain or stiffness

Pain or stiffness in the arms or legs

Muscle weakness or tenderness

 

Paralytic syndrome

 

 

 

This most serious form of the disease is rare. Initial signs and symptoms of paralytic polio, such as fever and headache, often mimic those of nonparalytic polio. Within a week, however, other signs and symptoms appear, including:

 

Loss of reflexes

Severe muscle aches or weakness

Loose and floppy limbs (flaccid paralysis)

Post-polio syndrome

Post-polio syndrome is a cluster of disabling signs and symptoms that affect some people years after having polio. Common signs and symptoms include:

 

Progressive muscle or joint weakness and pain

Fatigue

Muscle wasting (atrophy)

Breathing or swallowing problems

Sleep-related breathing disorders, such as sleep apnea

Decreased tolerance of cold temperatures

 

When to see a doctor

Check with your doctor for polio vaccination recommendations before traveling to a part of the world where polio still occurs naturally or where oral polio vaccine (OPV) is used, such as Central and South America, Africa and Asia.

 

Additionally, call your doctor if:

 

Your child hasn't completed the vaccine series

Your child has an allergic reaction to the polio vaccine

Your child has problems other than a mild redness or soreness at the vaccine injection site

You had polio years ago and are now having unexplained weakness and fatigue

 

Causes

Poliovirus can be transmitted through direct contact with someone infected with the virus or, less commonly, through contaminated food and water. People carrying the poliovirus can spread the virus for weeks in their feces. People who have the virus but don't have symptoms can pass the virus to others.

 

Risk factors

Polio mainly affects children younger than 5. However, anyone who hasn't been vaccinated is at risk of developing the disease.

 

Complications

Paralytic polio can lead to temporary or permanent muscle paralysis, disability, bone deformities and death.

 

Prevention

The most effective way to prevent polio is vaccination.

 

Polio vaccine

Most children in the United States receive four doses of inactivated poliovirus vaccine (IPV) at the following ages:

 

Two months

Four months

Between 6 and 18 months

Between ages 4 and 6 when children are just entering school

IPV is safe for people with weakened immune systems, although it's not certain just how protective the vaccine is in cases of severe immune deficiency. Common side effects are pain and redness at the injection site.

 

Allergic reaction to the vaccine

IPV can cause an allergic reaction in some people. Because the vaccine contains trace amounts of the antibiotics streptomycin, polymyxin B and neomycin, it shouldn't be given to anyone who's reacted to these medications.

 

Signs and symptoms of an allergic reaction usually occur within minutes to a few hours after the shot. Watch for:

 

Difficulty breathing

Weakness

Hoarseness or wheezing

Rapid heart rate

Hives

Dizziness

If you or your child has an allergic reaction after any shot, get medical help immediately.

 

 

 

Adult vaccination

In the U.S., adults aren't routinely vaccinated against polio because most are already immune, and the chances of contracting polio are minimal. However, certain adults at high risk of polio who have had a primary vaccination series with either IPV or the oral polio vaccine (OPV) should receive a single booster shot of IPV.

 

A single booster dose of IPV lasts a lifetime. Adults at risk include those who are traveling to parts of the world where polio still occurs or those who care for people who have polio.

 

If you're unvaccinated or your vaccination status is undocumented, get a series of primary polio vaccination shots — two doses of IPV at four- to eight-week intervals and a third dose six to 12 months after the second dose.

 

Rotary International vs. Polio: A Timeline

Rotary is an international community that brings together leaders who step up to take on the world’s toughest challenges, locally and globally. The eradication of polio is one of their longest standing and most significant efforts. Along with their partners they have helped immunize more than 2.5 billion children against polio in 122 countries. They have reduced polio cases by 99.9 percent worldwide and we won't stop until we end the disease for good.
