Define etiology.

Define etiology.

• A. The anatomical location of a disease
• B. The clinical signs of a disease
• C. The cause of a disease; includes all factors contributing to its development
• D. The treatment for a disease

Answer: (C)

Etiology is the cause or origin of a disease, including all factors that contribute to its development. It covers the immediate cause (such as a pathogen) as well as other influences like genetics, environment, lifestyle, and interactions between factors that raise risk or drive progression. This distinguishes etiology from where a disease occurs (anatomical location), what it looks like clinically (signs and symptoms), or how it is treated. For example, an infectious disease has a specific etiologic agent, but the full etiology may also involve host susceptibility and environmental conditions; multifactorial conditions involve several contributing factors rather than a single cause.
