A pandemic is an outbreak of a disease that occurs over a wide geographic area.

That definition was changed in 2009 to perpetuate the last pandemic hoax:

On June 11, 2009, WHO Director-General Margaret Chan declared H1N1 swine flu to be a global pandemic, triggering the dormant contracts and throwing the pharmaceutical and vaccine industry into high gear. Chan was able to make this declaration based on WHO’s official definition of a pandemic, which was updated just a month before declaring the H1N1 pandemic — WHO deleted its definition of a pandemic from the organization’s website and replaced it with a new, more flexible definition. Under the new definition, WHO no longer required that anyone die from an illness before the organization could declare a pandemic. The new definition stipulated only that infections be geographically widespread.
