What are non infectious?

Non-infectious diseases are diseases that are not caused by infectious agents, such as bacteria, viruses, or fungi. They can be caused by a variety of factors, including genetic defects, environmental toxins, or autoimmune disorders.

Some examples of non-infectious diseases include:

* Cancer: Cancer is a disease in which cells in the body begin to grow out of control. It is the leading cause of death worldwide.

* Heart disease: Heart disease is a group of conditions that affect the heart and blood vessels. It is the leading cause of death in the United States.

* Stroke: A stroke occurs when the blood supply to the brain is interrupted. It is the fifth leading cause of death in the United States.

* Chronic obstructive pulmonary disease (COPD): COPD is a group of lung diseases that cause airflow blockage. It is the third leading cause of death in the United States.

* Diabetes: Diabetes is a disease in which the body does not produce enough insulin, a hormone that helps glucose get into cells. It is the seventh leading cause of death in the United States.

Non-infectious diseases can be prevented and treated in a variety of ways. Prevention methods include eating a healthy diet, getting regular exercise, avoiding tobacco smoke, and limiting alcohol intake. Treatment methods vary depending on the disease.

It is important to remember that non-infectious diseases are not contagious. They cannot be spread from person to person through contact with bodily fluids or surfaces.
