• An epidemic is characterized by a rapid and significant increase in the incidence of a disease beyond what is normally expected in a given population or geographic area. It's distinct from an 'endemic,' where a disease is regularly found among particular people or in a certain area, and a 'pandemic,' which is a global outbreak of a new disease.
