In this lesson students will explore key concepts in public health, such as the definitions of “epidemic” and “intervention” and criteria for national and international emergencies. Using the film Survivors, students will learn about the science of the Ebola virus, including the symptoms of the disease and how it is spread. Finally, the class will examine local, national and international responses to the 2014-2016 Ebola epidemic in Sierra Leone and neighboring countries, and what those responses revealed about strengths and gaps in global public health policy.
