Infectious can be spread from person to person. This would include Viruses, Fungi, and STD's

Infectious Diseases are caused by pathogens , which are disease causing organisms. The major groups of pathogens are viruses, bacteria, fungi, protozoans and multi-cellular parasites.

Non-infectious diseases are not caused by pathogens but can be caused by physiological malfunction, environmental (or chemical) factors, heredity (e.g. faulty gene/chromosome combinations), unknown causes or a combination of factors.

This would mean that an illness you can 'catch' from some is contagious... such as influenza or an STD... but blood-poisoning or gangrene are non-contagious.
