What is infection?

Infection is when tiny invaders take over your body and make you feel sick.

Tiny invaders are like little bugs or germs that can’t be seen with the naked eye. They’re so small, they're more like dust particles than actual bugs. You might find them on a doorknob, a toy, or even your own hands after you sneeze.

When you touch something with tiny invaders on it and then touch your mouth, nose, or eyes, they can get inside your body like tiny tourists. Once they're in, they start to multiply, just like how a single seed grows into a big tree.

Your body tries to fight them off, but sometimes the tiny invaders win for a little while. That’s when you feel sick: coughing, sneezing, or even getting a fever. It's like your body is in a tiny battle with these germs!

So next time you get sick, remember, it's just your body fighting off some tiny invaders from the outside world!
