A pandemic is when a sickness goes from one person to many people all over the world, like a game of tag that everyone plays at once.
Imagine you have a toy that can make you sneeze, and when you sneeze, it sends tiny invisible particles flying. If your friend touches the same toy, they might get sneezes too. That’s how a virus spreads, it jumps from person to person through things like coughs, sneezes, or touching doorknobs.
How it travels far and wide
A pandemic doesn’t stop at your school or neighborhood. It can travel on airplanes, buses, or even in the air. It's like when you send a letter, the sickness goes along with people who are moving around, and then it finds new friends to infect.
Why it grows quickly
When more people get sick, they spread the virus even faster. It’s like starting a chain reaction: one person sneezes, two people catch it, those two people each tell four others, and soon you have a whole room of sneezing people!
So, that's how pandemics happen, it all starts with a tiny germ doing a big dance across the world.
Examples
- A virus travels from one person to another when they sneeze or cough near each other.
- People moving from city to city carry diseases with them, spreading illness across the world.
- Germs can live on surfaces and be passed along when someone touches them.
