Native and restricted to a particular geographic region; or a disease regularly found at stable levels within a community (as distinct from epidemic/pandemic)

Greek endemos, native (en = in + demos = people/land)

Native Indigenous Local (species) Resident (disease)
Exotic Invasive Cosmopolitan (species) Epidemic (disease)
"The Pygmy Hog is endemic to the grasslands of Manas National Park, found nowhere else in the wild except the Brahmaputra plains of Assam."

Critical distinction: endemic (always present at steady levels) vs. epidemic (sharp rise in cases) vs. pandemic (global spread). In biodiversity: endemic species have extreme conservation value because their extinction means global extinction. Frequently tested in Prelims (endemic species of Western Ghats, Andaman Islands). In health: COVID-19 transition to endemic status is a recurring current affairs theme.
