|What is a virus?
Well, a virus pretty much is a harmful message carried through cells.
How does a virus travel through cells?
You can break up the cycle of how they get into your cells into 6 steps.
1. Viruses invade host cells.
2. They give the message to the host cell.
3. The virus recruits "messengers" called enzymes.
4. The enzymes make more virus particles to send out the messages.
5. The particles overpower the host cell.
6. Then they break free from the host cell and spread out into other cells.
How is this like a school?
No school is perfect. The viruses are like bullies who try to overpower people. It doesn't always work because the white blood cells or the target's friends step in and make an end to it. The virus doesn't always go away quickly, but eventually it gets out.
