Endemic \En*de"mic\, Endemical \En*de"mic*al\, a. [Gr. ?, ?; ? +
   ? the people: cf. F. end['e]mique.] (Med.)
   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.
