Difference Between Infectious and Noninfectious Disease

There is a substantial difference between infectious and noninfectious disease. Infectious disease is caused by a pathogen that enters the body and can be transferred from person to person. Noninfectious disease is not caused by a pathogen or organism carrying disease.

A good example is which is spread through sexual relations. The pathogen enters the body as a virus or in some cases bacteria. Some of these diseases will not even have any symptoms.
