==Description==
In epidemiology, an '''epidemic''' (επι (epi)- [[meaning]] "upon or above" and δεμος (demos)- meaning "people"), occurs when new cases of a certain [[disease]], in a given [[human]] [[population]], and during a given period, substantially exceed what is expected based on recent [[experience]]. The disease is not required to be communicable. An epidemic may be restricted to one locale, or it may be global, in which case it is called a [[pandemic]]. A few cases of a very rare disease may be classified as an epidemic, while many cases of a common disease (such as the common cold) would not.
