Polio vaccine
Poliomyelitis (Polio): A Serious Nervous System Disease.
Poliomyelitis, commonly known as polio, is a viral infection that affects the central nervous system and can lead to paralysis in severe cases. The virus spreads through contaminated food or water and direct contact with an infected person.
While polio has been largely eradicated in many parts of the world, cases still occur in some African and Asian countries.
Signs & Symptoms
Around 95% of individuals who contract polio experience no symptoms. However, in cases where symptoms do develop, they can vary in severity, ranging from:
Mild illness – with fever and fatigue
Meningitis-like symptoms – inflammation of the brain lining
Paralysis – in severe cases, which can be life-altering
How do you catch Polio
Polio, or poliomyelitis, is a highly contagious viral infection caused by the poliovirus. It spreads primarily through person-to-person contact, making good hygiene and vaccination essential for prevention.
How Polio Is Contracted:
Fecal-Oral Transmission – The most common way polio spreads is through contaminated food or water, often due to poor sanitation or hygiene.
Direct Contact – Although less common, the virus can also spread through respiratory droplets from an infected person when they cough or sneeze.
Contaminated Surfaces – Poliovirus can survive on objects or surfaces, and touching these before touching the mouth, nose, or eyes can lead to infection.
Polio’s Hidden Risk – Many infected individuals show no symptoms but can still spread the virus to others. While anyone can contract polio, children under five are the most vulnerable and at greater risk of severe complications.
How is at risk from it
Polio can affect individuals of all ages, but certain groups are more vulnerable to infection and severe complications. Understanding these risks is crucial for prevention.
High-Risk Groups:
Unvaccinated Individuals – Those who have not received the polio vaccine or have incomplete immunization are at a greater risk of contracting the virus.
Children Under Five – Young children are the most susceptible to polio and are more likely to develop severe symptoms, including paralysis.
Individuals with Weakened Immunity – Those with HIV/AIDS, malnutrition, or other medical conditions that weaken the immune system are more vulnerable to infection.
Travelers to High-Risk Areas – People visiting or returning from regions where polio remains endemic or where outbreaks occur face an increased risk of exposure. Up-to-date vaccinations are essential for travel safety.
Healthcare & Laboratory Workers – Medical professionals and lab personnel handling poliovirus specimens may be at **higher risk of exposure** if proper safety measures aren’t followed.
Prevention Is Key
Widespread polio vaccination has dramatically reduced cases worldwide. Routine immunization, alongside good hygiene and access to clean water, plays a crucial role in preventing the spread of polio and protecting vulnerable populations.

Symptoms
Polio, or poliomyelitis, can range from no symptoms at all to severe complications such as paralysis or even death. Many infected individuals do not experience any symptoms and may unknowingly carry the virus. However, when symptoms do occur, they can vary in severity.
Non-Paralytic Polio (Most Common Form) This milder form of polio typically presents with:
Flu-like symptoms – Fever, headache, sore throat, fatigue, and muscle aches.
Gastrointestinal issues – Nausea, vomiting, abdominal pain, and diarrhea.
Meningitis-like symptoms – Stiff neck, light sensitivity, and irritability.
Paralytic Polio (Rare but Severe Form)
A small percentage of cases progress to paralytic polio, which can cause:
• Early symptoms – Fever, headache, sore throat, and muscle stiffness, similar to non-paralytic polio.
• Muscle weakness or paralysis – Often affecting one or more limbs asymmetrically, with potential impact on breathing and swallowing muscles.
• Loss of reflexes – Diminished or absent deep tendon reflexes.
• Floppy limbs & reduced muscle tone – Leading to long-term weakness.
• Permanent disability – In severe cases, paralysis can be irreversible, affecting mobility and daily life.
Polio Prevention: Vaccination Is Key
While most polio infections are mild or symptom-free, severe cases can lead to life-changing complications. If any polio-related symptoms appear, immediate medical attention is crucial.
Routine polio vaccination has been highly effective in reducing global cases. Continued immunization, surveillance, and monitoring are essential to eliminating polio worldwide.
