Definition

What is a noncommunicable disease?

A noncommunicable disease (NCD) is a condition that does not spread from one person to another. NCDs usually develop slowly and last a long time, which is why they are often called chronic diseases, and they arise from inherited, physiological, environmental and lifestyle influences acting together. The four main groups are heart and blood vessel diseases, including heart attack and stroke; cancers; long-term lung diseases such as COPD and asthma; and diabetes.

NCDs are the leading cause of death worldwide, responsible for roughly three in four deaths outside of pandemics, and many of these deaths occur before age 70 in low- and middle-income countries. Much of the burden traces to a handful of modifiable risk factors: tobacco, physical inactivity, unhealthy diets, harmful use of alcohol and air pollution. These in turn drive metabolic changes such as raised blood pressure, high blood sugar, high blood lipids and obesity, which lead on to disease.

Because NCDs are not caught from others, they are tackled mainly through prevention and long-term management rather than by breaking chains of transmission: tobacco taxes, healthier food environments, screening, early treatment and palliative care. The boundary is not always sharp, since some cancers, such as cervical and liver cancer, are triggered by infections.
