An epidemic is the name given to an infectious disease that rapidly spreads to a large number of people within a short period of time—usually two weeks or less. Epidemics have been happening for as long as there have been people living on Earth. They can be caused by several different factors, such as a virus being carried into an area, or changes in the way people live, like more people living in an area, which increases the chances of them coming into contact with a bacteria or virus.
