I need help with my case assignments and SLP's on epidemiology

Before you begin this assignment, read through the Home page and the required readings.  Specifically, view the E-learning course – Introduction to epidemiology video. 

As a health officer, you have been asked to discuss the subject of epidemiology to high school students getting ready to enroll in Winterton College.

Your task is as follows:

1. Define to them the field of epidemiology.
2. Briefly list a historical evolution of epidemiology.
3. Explain the terms outbreak and epidemic.
4. The Introduction to epidemiology video discussed the Legionnaire’s disease outbreak in 1976.  Briefly describe the case in terms of time, place, and person; and, what should have been the first step the Pennsylvania Department of Health should have followed?

Length: 2–3 pages, excluding title page and references.
