The CDC realizes disease outbreaks can and do happen. The CDC is continually investigating infectious diseases. They are on call 24/7 in the event of an outbreak, whether it is a single community affected, or the entire United States. The CDC is always preparing for an outbreak, with many trained scientists and laboratories involved. They conduct investigations, laboratory testing, patient care, and infection control. The goals of the CDC are to determine the cause and source of an infection, learn transmission routes, and learn how to break the cycle of transmission to prevent cases of disease. In the case of an outbreak, the CDC and other national and international agencies would deploy medical teams and first responders to affected areas (CDC, 2011). The CDC also works with state health departments and other organizations in order to control disease.
