Definition:

A virus is a small organism which can infect other biological organisms.

Viruses can only reproduce by invading and taking over cells as they lack the cellular machinery for self reproduction.

They cause diseases in human beings, animals, plants and bacteria.

Examples of human diseases caused by viruses include the common cold, influenza, small pox, AIDS, and cold sores.
