Imagine a virus is like a tiny pirate who can't move on its own. It needs to sneak into a bacterium, which is more like a strong sailor who can sail through the sea of your body all by itself. Once inside, the virus takes over and makes the bacterium create more pirates, more viruses.
Examples
- A cold is usually caused by a virus, while an infection from a cut on your hand might be due to bacteria.
- A virus can make you sick quickly, but a bacterium might take longer to cause trouble.
- When you get the flu, it feels like your body is being taken over, that's a virus at work.
