What is Polio?
Polio, or poliomyelitis, is a serious infectious disease caused by the poliovirus. This virus can invade the nervous system and cause paralysis, particularly affecting children. Before the development of the vaccine, many children suffered from polio, but thanks to vaccination, it is now nearly eradicated.
Causes and Transmission of Polio
The primary cause of polio is the poliovirus, which spreads through several routes:
- Fecal-Oral Route: The virus spreads through contaminated food or water.
- Unhygienic Conditions: It is more prevalent in areas with poor sanitation.
- Close Contact: The virus can spread through close contact with an infected person.
Symptoms of Polio
Polio is often asymptomatic or presents with mild symptoms, but severe cases can lead to serious consequences. The main symptoms include:
- Initial Symptoms: Fever, fatigue, headache, vomiting, neck, and back pain.
- Non-Paralytic Polio: Mild symptoms such as muscle aches, stiffness, and fatigue.
- Paralytic Polio: Severe cases can cause paralysis, and if respiratory muscles are affected, it can be life-threatening.
Importance of Polio Vaccination
Polio vaccination is a crucial preventive measure. Here are the key reasons for vaccination:
- Immunity Development: Vaccination helps build immunity against the poliovirus.
- Disease Eradication: Vaccination has nearly eradicated polio, preventing further spread.
- Public Health Improvement: Global vaccination programs prevent disease spread and improve public health.
Types of Polio Vaccines
There are two types of polio vaccines:
- Oral Polio Vaccine (OPV): A live attenuated vaccine administered orally, inducing immunity in the intestines.
- Inactivated Polio Vaccine (IPV): An inactivated vaccine administered via injection, inducing immunity in the blood.
Vaccination Schedule
In South Korea, the polio vaccination schedule is as follows:
- First Dose: At 2 months of age
- Second Dose: At 4 months of age
- Third Dose: At 6-18 months of age
- Fourth Dose: At 4-6 years of age
Side Effects of Polio Vaccination
Polio vaccination is generally safe, but some side effects may occur:
- Mild Side Effects: Fever, pain, and swelling at the injection site.
- Rare Side Effects: Allergic reactions, including anaphylaxis in severe cases.
If side effects occur, it is important to consult healthcare professionals for appropriate measures.
Necessity of Polio Vaccination
- Community Protection: Vaccination helps achieve herd immunity, protecting those with weaker immune systems.
- Global Eradication Goal: Polio still exists in some regions, requiring global vaccination efforts.
Conclusion
Polio is a preventable disease. Through vaccination, we can protect our children from polio. Parents should recognize the importance of vaccination and adhere to the recommended vaccination schedule. This not only safeguards the health of our children but also contributes to the global eradication of polio.
