The Short Answer

Let's look at a different word first: disease. Now, read it like this: Dis-ease. The prefix dis- means "not," while ease can mean "comfort," in the context of being healthy. Anything that makes you not healthy is a disease. However, there are both viruses and bacteria, especially the latter, that are good for you. You could not live without the good bacteria in your intestines, and some ancient viral DNA has been integrated into our own DNA to the extent that we cannot live without it. However, since they have no negative side effects, we do not call them diseases.
