The course will cover a brief history of infectious disease and its impact on Western Civilization, particularly in the past 500 years. We will discuss the scientific contributions of some significant figures like Pasteur, Jenner and Fleming who made major advances in the treatment of disease. A second focus will be on diseases that effect us today including flu, AIDS and hepatitis. The course will also cover a small amount of layman's science related to these disease areas. We will conclude with a look at some emerging diseases that may become the next plague and what, if anything, you might be able to do to protect yourself in the future. Lecture (plus questions).
