Endemic \En*de"mic\, Endemical \En*de"mic*al\, a. [Gr. ?, ?; ? +
? the people: cf. F. end['e]mique.] (Med.)
1. Peculiar to a district or particular locality, or class of
persons; as, an endemic disease.

Note: An endemic disease is one which is constantly present
to a greater or less degree in any place, as
distinguished from an epidemic disease, which prevails
widely at some one time, or periodically, and from a
sporadic disease, of which a few instances occur now
and then.

2. Belonging or native to a particular people or country;
native as distinguished from introduced or naturalized;
hence, regularly or ordinarily occurring in a given
region; local; as, a plant endemic in Australia; -- often
distinguished from {exotic}.

The traditions of folklore . . . form a kind of
endemic symbolism. --F. W. H.
Myers.
