More About Etiology

What does etiology mean?

The etiology of a disease is its cause or origin.

Etiology is also the name for the study of the causes of diseases. It can also refer to the study of the cause of things in other fields, such as philosophy and physics. But it is most commonly used in the context of medicine. In British English, it is spelled aetiology.

Example: The doctors have taken some samples and are working to determine the etiology of the disease.

Where does etiology come from?

The first records of etiology in English come from the mid-1500s. Etiology derives from the Greek aitiología, meaning “determining the cause of something.” This is formed from aitía, “cause,” and –logia, which is the basis of -logy, which indicates the study of something.

In medicine, etiology involves studying the factors that cause a disease. This is done for individual patients to determine how they became sick and to diagnose their illness. But it is also done on a broader scale to determine the origin of diseases. Epidemiologists study how diseases spread throughout large populations and try to detect the source and cause of epidemics.

When a cause of a disease is determined, this is called its etiology. For example, the etiology of cholera is known to be a bacterium that contaminates food and drinking water in places with poor sanitation.

Although etiology is most commonly used in medicine, it can also be used in the context of any field in which the causes of things are studied. An example of etiology in psychology is the study of the causes of mental disorders.
