How Does a ‘Flu’ Spread and Why Is It So Contagious?

A flu is like a sneaky guest that jumps from one person to another and makes them feel sick.

When someone has the flu, they have tiny little helpers inside their body called germs. These germs are like tiny, invisible bugs that can travel through the air or on things people touch.

When a person with the flu coughs or sneezes, it sends out tiny droplets, like little bubbles filled with germs, into the air. If another person is nearby and breathes in those droplets, they can catch the flu.

Also, if someone touches something that has germs on it, like a toy, a doorknob, or even a phone, and then touches their face (like their nose or mouth), the germs can go inside them too.

The flu is very contagious because those tiny germs are really good at spreading. They can jump from one person to another quickly, especially in places where people are close together, like a classroom or a playground. That’s why the flu can turn into a big party of sickness in just a few days!
