Introduction:
Polio, short for poliomyelitis, is a highly infectious viral disease that primarily affects young children, although it can also impact adults. While polio has been nearly eradicated in many parts of the world due to widespread vaccination campaigns, it remains a health concern in some regions. Understanding the symptoms of polio, methods of prevention, and the critical importance of vaccination can help ensure that this disease does not resurface as a global threat.
What Is Polio?
Polio is caused by the poliovirus, which spreads from person to person, typically through contact with contaminated water or food. The virus invades the nervous system and can cause paralysis in a matter of hours. In more severe cases, polio can lead to irreversible muscle damage, paralysis, and even death.
Polio mainly affects children under five, but anyone who has not been vaccinated is at risk. Thanks to the effectiveness of vaccines, the number of polio cases has dropped significantly over the years, but the threat is not entirely gone.
Symptoms of Polio
Most people infected with the poliovirus do not show visible symptoms, which makes it easier for the virus to spread unknowingly. However, for those who do exhibit symptoms, they are categorized into two main types: non-paralytic polio and paralytic polio.
Non-Paralytic Polio
Non-paralytic polio refers to cases where the virus causes mild flu-like symptoms without leading to paralysis. These symptoms generally last for 1-10 days and include:
- Fever
- Sore throat
- Fatigue
- Headache
- Vomiting
- Neck pain or stiffness
- Muscle pain or stiffness
- Abdominal pain
These symptoms are often mistaken for other viral infections, which can delay diagnosis.
Paralytic Polio
Paralytic polio, though rare, is the more severe form of the disease. It occurs when the virus spreads to the spinal cord and brain, leading to paralysis. Symptoms include:
- Sudden onset of weakness in limbs
- Loss of reflexes
- Severe muscle aches and spasms
- Difficulty breathing or swallowing
Paralysis is typically permanent and can affect any part of the body, especially the legs. In severe cases, paralysis of the respiratory muscles can be life-threatening.
Post-Polio Syndrome
Years after recovering from polio, some individuals may develop Post-Polio Syndrome (PPS). Symptoms of PPS include muscle weakness, fatigue, and joint pain. While it is not contagious, it can significantly affect the quality of life for those who had polio earlier.
Prevention of Polio
Polio prevention revolves around two main strategies: vaccination and maintaining good hygiene.
Vaccination: The Most Effective Defense
The most effective way to prevent polio is through vaccination. There are two types of polio vaccines:
- Oral Polio Vaccine (OPV): Administered orally, this vaccine contains weakened poliovirus strains that stimulate an immune response. OPV has been key in eradicating polio in many countries because it not only protects the individual but also reduces community transmission.
- Inactivated Poliovirus Vaccine (IPV): This vaccine is administered via injection and contains inactivated (killed) poliovirus. IPV is commonly used in areas where polio has been eradicated to ensure that the virus does not return.
Vaccination is usually given in multiple doses, starting from infancy. It is crucial to complete the entire series of vaccinations to ensure full protection against the disease.At Vasavi Hospitals, our expert team of physicians, including the best ortho in Bangalore and general physician in Kumaraswamy Layout, stress the importance of maintaining up-to-date vaccinations to safeguard against polio and other preventable diseases.

Hygiene and Sanitation
Since the poliovirus is primarily spread through contaminated water and food, good hygiene practices are critical in preventing its transmission. Steps such as washing hands regularly with soap and ensuring access to clean drinking water can help reduce the risk of infection.
Why Vaccination is Still Critical Today
Although polio has been eliminated from most countries, it remains endemic in some regions, and the virus could easily spread again if vaccination rates drop. Here are key reasons why continued vaccination is vital:
1. Global Travel Increases Risk
With international travel becoming more accessible, the potential for polio to spread across borders remains a concern. Even if polio is eradicated in one country, unvaccinated individuals can bring the virus back from regions where it still exists. This makes maintaining high vaccination coverage globally essential to prevent outbreaks.
2. Herd Immunity is Fragile
Polio vaccination provides “herd immunity,” meaning that when enough people are vaccinated, the virus has fewer opportunities to spread. However, if vaccination rates drop below a certain threshold, herd immunity weakens, and the risk of a resurgence increases. For polio, maintaining herd immunity is essential to protect those who cannot be vaccinated due to medical reasons.
3. Vaccine-Derived Poliovirus
While rare, cases of vaccine-derived poliovirus (VDPV) can occur in areas where OPV is used. In some instances, the weakened virus in the OPV can mutate and regain strength, leading to outbreaks. The solution to this issue is not to stop vaccinations but to transition from OPV to IPV in areas where polio has been eradicated, as IPV does not carry the same risk.
4. Re-Emergence of Polio
Even in regions where polio has been eradicated, re-emergence is a genuine concern if vaccination efforts are not maintained. The world has already seen small outbreaks of vaccine-derived polio in countries where vaccination campaigns have slowed. Continued vaccination is the only way to ensure that polio does not regain a foothold.
