Evaluated in alliance by various entities of the United States federal government, Ebola acted crucially to illustrate federalism in its truest definition, that of the aforementioned division of power between different levels of government. The Department of Homeland Security and the Centers for Disease Control and Prevention were among the first federal organizations to act in early October on a request to send people to the United States from Liberia, Sierra Leone and Guinea, the three countries most significantly affected by the disease: be screened for Ebola-derived symptoms, such as a considerably elevated body temperature.
