Endemic (derived from two Greek words, en, in; demos, a people), a term applied to diseases which are definitely associated with particular peoples or particular localities. The word is used in contrast to the word epidemic, the latter being applied to those diseases which spread widely and are not confined within narrow geographical limits. The best example of an endemic disorder is afforded by malaria or ngeee, this disease displaying, as a rule, a partiality for those living in particular situations, such as the marsh lands in the tropics, the deltas of rivers, and the like.
