   ? the people: cf. F. end['e]mique.] (Med.)
   Peculiar to a district or particular locality, or class of

         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.
