An epidemic (from Greek epi- upon + demos people) is a disease that appears as new cases in a given human population, during a given period, at a rate that substantially exceeds what is "expected", based on recent experience (the number of new cases in the population during a specified period of time is called the "incidence rate".

Simply put: an epidemic is when the infectious disease is more or less localized to a certain region of the world (e.g. malaria). A pandemic is when the disease has the potential to spread to all parts of the world (e.g. avian bird flu).
