Sample Solution

The World Health Organization (WHO) recommends immunization for a variety of diseases, but some are particularly important due to their global prevalence and severity. Here are five immunizable diseases highlighted by WHO:

1. Diphtheria: This bacterial infection causes inflammation of the respiratory tract, leading to difficulty breathing, paralysis, and even death. Vaccination is highly effective and crucial for preventing outbreaks.

2. Measles: This highly contagious viral infection causes fever, rash, and respiratory symptoms. It can lead to severe complications like pneumonia, encephalitis (brain inflammation), and death. Measles vaccination is essential for global control and elimination.

3. Polio: This crippling viral disease attacks the nervous system, causing paralysis and lifelong disability. While close to eradication thanks to widespread vaccination, polio remains a threat in certain regions. Continued vaccination efforts are crucial to prevent its resurgence.

4. Tetanus: This potentially fatal bacterial infection causes painful muscle spasms, often leading to lockjaw. It can be contracted through wounds contaminated with tetanus spores. Tetanus vaccination is vital for both children and adults, especially those at risk through occupational hazards.

5. Yellow fever: This mosquito-borne viral infection causes fever, jaundice, and organ damage. It can be fatal if untreated. Vaccination is recommended for travelers visiting areas with high yellow fever risk and for residents in those areas.

These are just five examples, and the list of immunizable diseases is more extensive. WHO prioritizes these based on factors like:

• Global burden: High morbidity (illness) and mortality (death) rates.
• Transmission potential: Highly contagious and easily spread.
• Vaccine effectiveness: Proven and effective vaccines available.
• Cost-effectiveness: Vaccination offers significant cost savings compared to treating the disease.

Remember, vaccination is one of the most effective ways to prevent infectious diseases and protect yourself and your community. It's crucial to stay informed about recommended vaccines and follow immunization schedules for optimal health protection.
