How does the government prevent the spread of contagious diseases?

The Centers for Disease Control and Prevention (CDC) is the US government agency responsible for identifying, tracking and controlling the spread of contagious disease. With the help of the CDC, state and local health departments have created emergency preparedness and response plans. In addition to early detection, rapid diagnosis and treatment with antibiotics or antivirals, these plans use two main traditional strategies—quarantine and isolation—to contain the spread of illness. These are common healthcare practices to control the spread of a contagious disease by limiting people's exposure to it.
