Polio and Post-Polio Syndrome

What is polio?

From: MedlinePlus, National Library of Medicine

Polio, or poliomyelitis, is a disease that spreads from person to person. It is caused by the poliovirus. The virus attacks the nervous system. In serious cases, it can cause paralysis (where you can't move parts of the body). The paralysis may be lifelong and can sometimes be life-threatening.

Because of vaccines, polio is rare in the United States. But polio does occur in some parts of the world, and travelers can spread the virus.

How does polio spread?

From: MedlinePlus, National Library of Medicine

The poliovirus is very contagious. It spreads through contact with:

This contact can happen if:

People who have the infection can spread it to others just before and up to several weeks after the symptoms appear. People who don't have symptoms can still spread the virus to others and make them sick.

• The stool (poop) of person who has the infection
• Droplets from a sneeze or cough of someone who has the infection
• You get contaminated stool or droplets on your hands and then touch your mouth
• A child puts contaminated toys or other objects into their mouth
• You share food or utensils with someone who has the infection

Who is more likely to develop polio?

From: MedlinePlus, National Library of Medicine

Polio mainly affects children under age 5. But people of any age (including adults) who are unvaccinated are at risk of developing polio. People who live in or travel to areas where there is polio are more likely to get polio.

What are the symptoms of polio?

From: MedlinePlus, National Library of Medicine

Most people who get infected with poliovirus do not have any symptoms. But one out of four people who get polio will have flu-like symptoms. These symptoms usually last 2 to 5 days, and they include:

In rare cases, polio can be very serious. It can lead to:

• Sore throat
• Fever
• Fatigue
• Nausea
• Headache
• Stomach pain
• Meningitis, an infection of the covering of your spinal cord and/or brain.
• Weakness or paralysis in your arms, legs, or both. This paralysis or weakness can last a lifetime. It is possible for the paralysis to become life-threatening if it affects the muscles that you use to breathe.
• Post-polio syndrome (PPS), which happens later in life.

What is post-polio syndrome (PPS)?

From: MedlinePlus, National Library of Medicine

Post-polio syndrome (PPS) is a condition that affects polio survivors many years after they recovered from polio. It usually happens 15-40 years later. It is not contagious.

People who get PPS start having new weakening in muscles that were previously affected by the polio infection. Symptoms may range from mild to serious. The symptoms of PPS include:

• Muscle weakness
• Muscle atrophy (wasting away of muscles)
• Loss of muscle function
• Mental and physical fatigue
• Joint pain
• Curving of the spine (scoliosis)

PPS is rarely life-threatening, but the symptoms can interfere with your daily life.

How is polio diagnosed?

From: MedlinePlus, National Library of Medicine

If you think you or someone in your family has symptoms of polio, call your healthcare provider right away or go to an emergency room.

To find out if you or your child has polio, the provider:

• Will do a physical exam.
• Will take a detailed medical history, including your vaccination history and history of any recent travel.
• Will collect samples of body fluids, such as stool, saliva, blood, urine, and spinal fluid. Poliovirus is most likely to be detected in stool specimens.
• May do an MRI to look at pictures of the spinal cord.

What are the treatments for polio and post-polio syndrome (PPS)?

From: MedlinePlus, National Library of Medicine

There is no cure or specific treatment for polio. For a mild case, getting rest and drinking plenty of liquids may help with some of the symptoms.

If the polio is more serious, you or your child may need:

There is no cure for PPS. Treatments may help you manage your symptoms. They include:

• Physical or occupational therapy to help with arm or leg weakness. The earlier therapy is started, the better.
• Pain relievers to help with pain and treat fever. If your child is sick, do not give them aspirin unless their provider tells you to.
• A ventilator to help with breathing if the breathing muscles are weak or paralyzed.
• Non-fatiguing exercises (exercises that do not cause pain or fatigue that lasts more than 10 minutes). These exercises may improve muscle strength and reduce tiredness. Your provider can help you figure out which exercises are best for you.
• Mobility aids.
• Ventilation equipment.
• Lifestyle changes, such as eating a healthy diet, getting enough sleep, and not smoking.

Can polio be prevented?

From: MedlinePlus, National Library of Medicine

There are two types of vaccine that can prevent polio:

Children in the United States get four doses of PV as part of their routine childhood immunizations. Most adults in the United States were vaccinated against polio as children.

There is a one-time IPV booster. It may be given to adults who have completed their polio vaccinations but are at higher risk of contact with poliovirus. You may be at higher risk if you are:

Another way to help prevent the spread of polio is to wash your hands often with soap and water. Alcohol-based hand sanitizers will not kill poliovirus.

• Inactivated poliovirus vaccine (IPV) given as an injection in the leg or arm, depending on how old you are. Since 2000, this has been the only polio vaccine used in the United States.
• Oral poliovirus vaccine (OPV) is given as drops in the mouth. It is still used throughout much of the world.
• Traveling to a country where the risk of getting polio is greater
• Working in a laboratory or healthcare setting and handling samples that might contain polioviruses
• A healthcare worker who has contact with patients who could have polio

Which doctor should you see?

The suggested department for discussing Polio and Post-Polio Syndrome is Orthopaedics, with a orthopaedic specialist as the relevant type of clinician. General physician / Family Medicine; paediatrician for children. Referral depends on symptoms.

This is an editorial referral starting point. The appropriate clinic depends on the person’s age, symptoms, previous diagnosis and local services. The first clinician can decide whether another specialty or a team is needed; a department label does not confirm the diagnosis.

How to prepare for an assessment

Bring a short timeline of the main symptoms: when they first appeared, whether they are constant or episodic, what seems to change them, and how they affect daily activities. Include previous reports, discharge summaries, current medicines and supplements, allergies, and any relevant family history. A dated record is more useful than trying to match every feature in an online article.

Ask the clinician what is already established and what remains uncertain. If a test is suggested, ask what question it answers, what its limitations are and how the result would change the next step. The information here is not an instruction to arrange every possible test. In children, bring growth, developmental and school information if it is relevant to the concern.

• What explains the change in pain, movement or function?
• Which activities need adjustment while the diagnosis is being clarified?
• What are the roles of rehabilitation, observation and surgery in this situation?

Treatment discussions and follow-up

Where the source describes treatments, these are an overview of possible care, not a prescription for an individual. Ask which option applies to the confirmed diagnosis, what benefit is expected, what adverse effects to watch for and how progress will be assessed. Availability, approvals and local practice can differ from the country described in the source.

Before leaving the appointment, clarify the next review date, who will communicate results, and whom to contact if the situation changes. Discuss difficulties with sleep, work, school, mobility, eating or emotional wellbeing when these are relevant. Practical support may require coordination between the treating clinician and other services.

When to seek emergency help

Severe breathing difficulty, collapse, new stroke-like symptoms, a seizure that is prolonged or repeated without recovery, uncontrolled major bleeding, or an immediate risk of self-harm require emergency help. In India, call 112 or reach the nearest emergency department. This is a general, non-exhaustive warning list; it is not a condition-specific triage tool.
