How They Jump
When someone with a virus coughs, tiny droplets go flying through the air. If someone else breathes them in, the virus finds its way into their body and starts playing tag too.
The Sneaky Ways
Viruses can also jump by touching, like shaking hands or sharing a glass of water. They’re so small that they can even travel on surfaces, waiting for another person to touch them.
Examples
- A virus jumps from one child to another when they share a toy in the playground.
- A virus hides on a doorknob, and then someone touches it and then their face.
