How the Flu Virus Infects Your Body?

The flu virus is like a tiny sneaky guest that wants to stay in your body and make you feel sick.

Imagine your body is a big house, and each cell is like a room. The flu virus is like a tiny key that can open the door to one of those rooms, your cells. When someone who has the flu coughs or sneezes, they send out little tiny bubbles full of viruses into the air.

If you're near them, some of those bubbles might float over to your nose or mouth and stick there, like a piece of gum on the floor. Then, the virus slips inside, finds its way into your cells, and starts to make copies of itself, it's like having a tiny factory inside each cell!

Once that factory is working hard, your body feels tired and achy because all those factories are making more viruses, and your body is trying to fight them off. That’s why you might feel like you've been run over by a truck, but don’t worry, it's just the flu virus having its fun inside you!
