Viruses are not cells, but have a protein coat or capsid, surrounding a nucleic acid. In some viruses the nucleic acid is DNA (eg hepatitis B virus), in others it is RNA (eg HIV). In some viruses, the capsid is surrounded by an envelope of liquid and proteins, derived from the plasma membrane of the previous host cell.

This is not true, what about all the bacteria in your mouth and inside your stomach?

Some do, some don't. Not ALL cause infection. Otherwise we'll all be dead.
