Infectious diseases are those diseases which are caused by infectious agents (which include microorganisms such as bacteria, fungi, protozoa and virus, as well as some multicellular animals such as worms) and hence they are the ones which can spread from one person to another. Non-infectious diseases are those diseases that are not caused by infectious agents and do not spread from one person to another.

This theory revolutionized our understanding of infectious diseases and laid the foundation for modern medicine and public health practices.
