EN-DEM'IC, or EN-DEM'IC-AL, a. [or EN-DE'MI-AL. Gr. ενδημιος, εν, and δημος, people.]

Peculiar to a people or nation. An endemic disease, is one to which the inhabitants of a particular country are peculiarly subject, and which, for that reason may be supposed to proceed from local causes, as bad air or water. The epithet is also applied to a disease which prevails in a particular season, chiefly or wholly in a particular place.
