Since different diseases require different balances and interactions between these three factors, its critical to fully assess each component in order to develop effective control and prevention measures. Because the agent-host-environment model did not work well for many non-infectious diseases, several other models that attempt to account for the multifactorial nature of causation have been proposed. Those vertices are WebWelcome to the module on Epidemiology: Understanding the Spread of COVID-19. The activity also will help you teach about the scientific concept of the Epidemiologic Triangle using an infectious disease example. Riviers online degree programs allow you to learn in a dynamic, flexible environment that supports your professional goals while enabling you to work full-time and maintain your personal commitments.
