Epidemiology Investigation Concepts

The video provides an introduction to epidemiology, explaining its role in public health and the methods used by epidemiologists. It covers the public health approach, including surveillance and intervention strategies, and delves into the practical application of epidemiology through case studies and data analysis. Key concepts such as descriptive and analytic epidemiology, study designs, and outbreak investigation steps are discussed.

What is the first step in the public health approach to solving a health problem?

How is a rate in epidemiology calculated?

• Number of cases multiplied by the time period
