Specializes in Infectious Disease

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).
