What is an example of a non-communicable disease?

Diabetes serves as a prime example of a non-communicable disease because it is not caused by infectious agents and cannot be transmitted from person to person. Instead, diabetes is primarily a chronic metabolic disorder characterized by elevated blood sugar levels, which can result from either the body's inability to produce adequate insulin or the cells' resistance to insulin's effects.

Non-communicable diseases, such as diabetes, often stem from a combination of genetic, environmental, and lifestyle factors, and they typically develop over a long period. Their management focuses on lifestyle changes, medication, and monitoring rather than isolation or containment, which are necessary for infectious diseases. In contrast, options like influenza, HIV/AIDS, and tuberculosis are all infectious diseases that can spread from person to person through various forms of contact or exposure.
