How Does Movement of virus in human body Work?

Viruses are tiny travelers that move through our body like little bugs on a playground.

Imagine your body is like a big city, and viruses are like kids who want to go from one part of the city to another. They start at the door, which could be your nose or mouth, just like when you walk into a new place. Once they're inside, they ride along with the trains (like the air we breathe) or get on buses (like our blood). These trains and buses take them from one part of the city to another, helping them reach places like your lungs or your stomach.

• Trains (air): When you breathe in, viruses can ride along with the air, it's like being on a train that goes all over the body.
• Buses (blood): Once inside, some viruses get into our blood and travel through veins and arteries, which are like roads for the blood.

Sometimes these tiny travelers cause trouble by making your city feel sick. But they're just doing what any kid would do, exploring new places in the body city!
