N: 1. When a disease is prevalent in an area over long periods of time, it is considered to be endemic in that area. When the prevalence of disease is subject to wide fluctuations in time, it is considered to be epidemic during periods of high prevalence. Epidemics prevailing over wide geographic areas are called pandemics.
An endemic disease is restricted to a place, as with malaria, or a people, as with Tay-Sachs. An epidemic disease may happen in a specific place, but it can spread beyond that place, as with asthma or AIDS.
2. A disease that is endemic is found in a certain geographic region or in a specific race of people. Malaria is endemic to parts of Africa because it’s hot and skeeters love it. Tay-Sachs is a genetic disease endemic to Jews and French Canadians. On the brighter side, a plant or animal can also be described as endemic to a region. If it’s in the system, it’s endemic.
