The flu is caused by a virus, just like the common cold, but it's a different virus, and it hits you harder. Imagine two types of invaders: one knocks you over with a punch, while the other just tugs at your arm. The flu feels worse because the virus spreads faster in your body and makes you feel sicker right away.
Examples
- A cold feels like being mildly annoyed by your neighbor, but the flu is like getting hit in the face with a brick.
- You can still walk to school with a cold, but the flu might keep you stuck in bed for days.
- Cold viruses are like little pranksters; flu viruses are like bullies.
