When a co-worker shows up to work sick and a few days later everyone else is sick, you surely know who to blame. But not every disease can be caught from someone else. Diseases that are not contagious are called non-infectious or non-communicable diseases because they can't be spread from one person to another. So there's no vector for them to move from one host to another, no virus, no bacteria, no pathogen.

Instead, these diseases are caused by other factors, such as genetics, environment, and lifestyle behaviors. Some can be prevented, while others are completely out of your control. Let's take a closer look at what these diseases are, how you get them, and what you can do about them once you have them.

Examples of Non-Infectious Diseases

Many non-communicable diseases are linked to our genes, such as autoimmune diseases. These are diseases that cause the body to attack itself instead of simply fighting off foreign intruders. Rheumatoid arthritis, multiple sclerosis, lupus, and celiac are all diseases that turn the body on itself.

Cancers are non-communicable diseases, and the causes of different cancers vary widely. Cancers arise from a genetic mutation that doesn't stop those cells from growing out of control. Sometimes these mutations occur naturally, but they may also be triggered by things such as sun exposure, smoking, and other harmful activities.
