When does an epidemic become a pandemic?

An epidemic is an event in which a disease is actively spreading. In contrast, the term pandemic relates to geographic spread and is used to describe a disease that affects a whole country or the entire world.

While casual use of epidemic may not require such nuance, it's important to know the differences between these two terms (and similar ones like outbreak and endemic) when considering public health news. In addition, from an epidemic standpoint, terms like these direct the public health response to better control and prevent a disease.
