  • Answer: A disease that cannot be spread is also known as a non-infectious disease. This is a disease that may be caused by the environment (e.g. skin cancer from radiation from the Sun), or lack of food (e.g. scurvy from lack of Vitamin C), genetic disorders, or any source other than an infection. They can also be caused by drugs and carcinogens (cancer-causing agents).

    Non-infectious diseases cannot be spread from person to person as in infectious disease, but can be passed down genetically in some cases. It is important to note that non-infectious diseases are not caused by bacteria, viruses, fungi or parasites; diseases caused by these organisms are infectious diseases.

    Examples of non-infectious diseases include:
    • Cardiovascular disease
