What Defines An Epidemic?

An epidemic is something, generally a disease that spreads at a rapid speed through infection. It has ill effects on a lot of people in a location, for example an epidemic of cholera. The disease in question is always contagious, either through food, water or air.

An epidemic is defined as the happening of incidents involving the disease, at a surplus of normal expectations for a number of people for a certain time period.

An illness that is limited to a certain region may spread further and turn into an epidemic if preventive measures of immunisation are not taken.
