WHO

WHO stands for the World Health Organization, a United Nations agency that works to improve health for people all over the world.

• What it does: WHO helps countries prevent diseases, control outbreaks, and improve everyday health services like vaccination, safe drinking water, and maternal care.
• Why it matters: Many health problems (like pandemics, air pollution, and malnutrition) cross borders, so countries need a common plan and shared information.
• Setting standards: WHO gives scientific guidelines on things like nutrition, medicines, and how to treat and track diseases, so doctors and governments can make better decisions.
• Emergency role: During outbreaks or disasters, WHO supports testing, supplies, and advice to reduce spread and save lives.
• Big idea behind the name: WHO looks at health as more than just “no disease” — it includes physical, mental, and social well-being, so health is connected to lifestyle and surroundings too.

In simple terms, WHO is like a global health “coach” that helps the world stay healthier through science, cooperation, and planning.
