These diseases are not spread from person to person like infectious diseases.

How is a non infectious disease different from a infectious disease?
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.
A person with HIV infection gets diseases a healthy person would not get?
HIV effects the cells associated with immune function. Over time, a person with HIV may experience an inability to recover from infections due to decreased immune function. Once an individual has reached a certain degree of immune deficiency, they are susceptible to what is known as "opportunistic infections." Opportunistic Infections are diseases that people with normal immune function are not at risk of being infected by. Opportunistic infections are found in patients who suffer from a variety of disorders associated with immune function.
