You can't describe a virus as a living organism...it's not living!

A virus needs a host to survive and replicate itself to create a illness. It invades a cell by attaching itself onto it and injects its DNA into the cell. Afterwards, the cell bursts and creates the new virus replica. Every cell that is affected by a virus always dies.
