While endemic vs epidemic vs pandemic affects people, there are differences amongst them.

An endemic can be a disease OR a plant or animal. Whichever it is, it’s local and common to that area.

An epidemic is also local — within a community, population, or region, but definitely refers to a disease affecting a large number of people. In that area.

A pandemic is a global epidemic that encompasses the world.
