Living with Poliomyelitis

A viral disease that can affect nerves and cause muscle weakness or paralysis; many infections cause few or no symptoms.

Understanding Poliomyelitis

Poliomyelitis (polio) is a viral disease that can affect nerves and lead to partial or full paralysis.

It is caused by the poliovirus, which spreads by direct contact, by contact with infected mucus from the nose or mouth, or by contact with infected feces. There are three patterns: subclinical, nonparalytic and paralytic. Symptoms range from none to partial or full paralysis. Since the polio vaccine was developed, the disease has become much less common.

Signs & symptoms

Symptoms depend on the pattern of infection. GARD lists these among the most common:

  • Fever
  • Headache
  • Tiredness (fatigue)
  • Muscle aches and joint pain
  • Muscle weakness, especially in the legs
  • Muscle shrinking and floppiness

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include brain and nervous system specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    Post-Polio Health International may keep lists of experts for this condition.
