Computer virus vs biological virus

A virus is a piece of code that can hide inside other pieces of code.

Viruses can spread from person to person through close contact. For example, if someone sneezes on you, you can pass the virus to them. They can then pass it to someone else, and that person can pass it to you.

Bacteria, which include viruses, can also spread from person to person.

Sometimes, viruses can cause a disease. For example, colds often spread from person to person. Some people get a cold when they inhale the virus. Others get a cold from touching something that has the virus on it, such as a doorknob.
