Describe the traditional epidemiology triangle.

Question

What will be an ideal response?

Answer 1

One of the key concepts of epidemiology is the traditional epidemiology triangle, a graphic demonstration of the relationship between the agent, environment, and individual as a function of time.  The triangle is composed of three parts: agent (what causes the disease), host (personal characteristics of those affected by the disease), and environment (external factors that cause or allow disease to be spread).  Another important part that ties into the elements of the triangle and is crucial in understanding disease transmission is time.  The traditional epidemiology triangle is most appropriate for the study of infectious diseases.
