Launching an outbreak investigation requires planning and strategy. In public health epidemiologists and other public health experts use a series of steps to answer 3 key questions, “what is the problem?, what is the cause? and what can we do about it?”. They use information and data to make decisions throughout an outbreak investigation. Sometimes, the data is not easy to read. So, experts use a variety of strategies and studies to try to identify the source of an outbreak and what works to control it. Because every scenario is different, it is important for them to think critically about how to interpret and use results to solve the problem.
In this section, students use research, engineering, and communication strategies to respond to outbreak scenarios like a disease detective.
Students will learn how to:
•Synthesize empirical data for the purpose of assessing need and risk
•Develop evidence-based explanations regarding cause and effect
•Prioritize operational tasks to achieve solutions
Mar 20, 2020 · When a disease outbreak like this occurs, a team of epidemiologists and other medical specialists is often sent to investigate and to identify the cause of the disease.

Learning Objectives. After successfully completing this section, the student will be able to: Define the terms outbreak, epidemic, endemic, and pandemic. List the steps in the investigation of an outbreak. Given the initial information of a possible disease outbreak, describe how to determine whether an epidemic exists.
As a class, walk through the section of the case study and answer questions together. Hand out NERD Outbreak, Step 4. As a class, walk through the section of the case study and answer questions together. Continue this process until all five sections of the case study are complete. Use the NERD Outbreak, Answer Key.
Outbreak investigations, an important and challenging component of epidemiology and public health, can help identify the source of ongoing outbreaks and prevent additional cases. Even when an outbreak is over, a thorough epidemiologic and environmental investigation often can increase our knowledge of a given disease and prevent future outbreaks.
