How do i describe a viruses physical appearance? How do I give a physical description of a virus NOT the symptoms that it causes in a person.

Well all viruses are different...

The most simple viruses have only two parts:  1) a genome (DNA or RNA) that is a blueprint with instructions for making more viruses and 2) a capsid protein shell that protects the genome. Viruses also often have proteins called receptors that stick out of the shell, and help the virus sneak inside cells.

Many viruses that infect humans and animals also have an envelope, something like a cell membrane, around the capsid and genome.
