Microorganisms: Infectious diseases are caused by pathogenic microorganisms: bacteria, viruses, fungi, and parasites. Everything else is non-infectious (except for the "non-infectious" diseases that will turn out to be infectious once we figure out what really causes them).

Prevent/avoid them.: There are many differences in these broad topics, but one of the largest ones to me is that you can prevent/avoid infectious diseases, whereas it is a great deal more difficult to avoid non-infectious ones. Heart disease, for example, happens in many people no matter what they do to prevent it. Std's can be avoided, and treated, especially if they're caught in time.
