- The distinction between the terms outbreak, epidemic, and pandemic is often blurred, even among epidemiologists. Part of the reason for this is that some diseases become more widespread or lethal over time, while others become less, forcing the CDC to adjust the models it uses to describe them. Epidemiologists have to be cautious about how they des...

Still, the actual staging of an epidemic, which outlines when the disease spread is severe enough to take specific actions, can vary based on the pathogenesis (pathway) of a disease and numerous other factors. The one staging model used to direct the public health response specifically involves influenza (the flu). I…

Once the disease affects large po…
