Which classification of disease is determined by its cause or origin?

The classification of disease determined by its cause or origin is known as etiology. Etiology focuses on identifying the specific factors that lead to the development of a disease, including infectious agents, genetic predispositions, environmental influences, and lifestyle choices. Understanding the etiology is crucial for diagnosis, treatment, and prevention, as it allows researchers and healthcare professionals to trace back the origins of diseases and address the underlying causes effectively.

Anatomical classification refers to identifying diseases based on the affected body structures or systems rather than their causes. Systemic diseases involve multiple systems or the entire body as opposed to affecting a localized area. Acute diseases are characterized by their rapid onset and severe symptoms but do not address the underlying cause of a disease. Thus, etiology stands out as the classification that directly correlates with the cause or origin of a disease.
