Definition of Endemic
Endemic: Present in a community at all times but in relatively low frequency. Something that is endemic is typically restricted or peculiar to a locality or region.
For example, malaria is endemic in some areas of Africa. And traffic in illicit drugs is endemic in some neighborhoods.
By contrast, there are the related terms "epidemic" and "pandemic":
The word "endemic" comes from the Greek "en-", "in" + "demos", "people or population" = "endemos" = "in the population." An endemic is in the people.
By contrast, "epi-" means "upon." An epidemic is visited upon the people. And "pan-" means "all." A pandemic affects all the people.
