What Is The Epidemiologic Triangle

Satisfactory Essays

The Epidemiologic Triangle is a model used to show the balance of health and disease as a united state of three factors: agent, host and environment. The agent or microbe is what causes the disease, the host is an organism harboring the disease or a population at risk for developing the disease, and the environment is the contributing external factors that cause or allow disease transmission This model helps us to understand how the agent, host and environment coexist with each other in a state of equilibrium or balance and then represents the spread of disease or injury when there is a shift to that equilibrium or balance
