Explanation:

A disease or infection is categorized as an epidemic when it affects a relatively large number of members of a population or locality. The spread of epidemic diseases is usually associated with specific conditions such as entry of a new pathogen in the population, contaminated food or water supply, etc. For example, the supply of contaminated water may affect a large number of individuals present in that locality with cholera. In this case, cholera will be an epidemic.
