An endemic disease always has a steady, predictable number of people getting sick, but that number can be high (hyperendemic) or low (hypoendemic), and the disease can be severe or mild. [3] [4] Also, a disease that is usually endemic can become epidemic. [3] For example, chickenpox is endemic in the United Kingdom, but malaria is not.
The word endemic is from Neo-Latin endēmicus, from Greek ἔνδημος, éndēmos, "native". Endēmos is formed of en meaning "in", and dēmos meaning "the people".

Endemic is a frequently misunderstood and misused word outside the realm of epidemiology. Endemic does not mean mild, or that COVID-19 must become a less hazardous disease.

Today, many of the remaining endemic species of plants and animals in the Hawaiian Islands are considered endangered, and some critically so. Plant species are particularly at risk: out of a total of 2,690 plant species, 946 are non-indigenous with 800 of the native species listed as endangered. [4]
In many places of Asia and Africa, hepatitis B has become endemic. [24] In addition, a person is sometimes infected with both hepatitis B virus (HBV) and HIV, and this population (about 2.7 million) accounts for about 1% of the total HBV infections. [23]
An endemic disease is one with a continuous occurrence at an expected frequency over a certain period of time and in a certain geographical location. Two terms are used when the degree of transmission or infection of an endemic disease is high: hyperendemic and holoendemic .
An Endemic Bird Area (EBA), a term devised by BirdLife International, is a geographical (rather than political) region of the world that contains two or more restricted-range (of no more than 50,000 km 2) species, while a "secondary area" contains one restricted-range species.
