Question

What is disease triangle? Explain different factors influencing diseases triangle with suitable example.

Answer 1

The disease triangle is a conceptual model that shows the interactions between the environment, the host and an infectious (or abiotic) agent.

                         These three elements, pathogen, host, and environmental conditions, make up the disease triangle. The disease triangle is a concept that illustrates the importance of all three elements—just as there are three sides to a triangle, there are three critical factors necessary for disease to develop.
