PHU 002: Epidemiological Triad or Triangle of Disease Causation

This is one triangle you don't want to miss.

The Epidemiological Triad or Triangle consists of:

• Agent
• Host
• Environment

Join me as we unpack this triad and fit the current COVID-19 pandemic into this triangle. 

You can further fit other infectious diseases into this triad and discover how each component interact and cause disease. By knowing how they interact and cause disease, we can better manage our risk of getting infected as well.
