Dictionary definition~an outbreak of epidemic disease
Student definition~spreading of infectious disease in large numbers of people
An epidemic spread is also known as a plague. A plague is a disease that is spread throughout large numbers of peoples, to cities, and even states. This kind of case is terrifying, for at times when people are struck with poverty, and a plague arrives, many people don't have enough money to hire doctors. In this case, doctors don't have customers and lose money. When no one has money to buy food and supplies, stores and banks close. When a plague arrives, its just like the Great Depression all over again. But that was old times. In the modern times, there are rarely any plagues.
