An epidemic is when a disease spreads quickly through a population, infecting a large percentage. Disease is spread by infection. When a person with a disease passes it to a new person, they 'infect' that new person. Some diseases travel from one person to the next very easily and the epidemic is very fast. For example, in 1919, Spainish Flu raced around the world killing maybe 20 million people in a couple of years. Spainish flu was very very 'contagious' and could jump from one person to the next very quickly. Sneezing projects the flu virus into the air and then it's breathed in by another person who becomes infected. This is an air-borne disease.
Other epidemics are slower. The AIDS virus cannot travel across the air in sneezes, AIDS is passed when an infected person has sex with another person. This is a sexually transmitted disease. So the AIDS epidemic travels more slowly.
Infected insects often trasmit disease by biting people and giving them the disease.
Dirty food and dirty water often spread disease. The largest cause of disease on the planet is probably dirty water. The World Health Organisation estimates 25 million people a year die because of infections from water-borne diseases.
In the end, disease is due to lack of hygiene. Clean water, clean food, clean hands and isolating infected people reduces the chance of epidemics.

How many people have to die before a disease is considered an epidemic?
None. An epidemic isn't considered on the amount of casualties, but in the ability of the disease to spread, and its ability to infect its host. While sadly, some diseases have to claim a few lives before it is recognized as an epidemic or pandemic, the mortality rate isn't the cause of it being labeled as such. For instance, Lice infestation could be considered an epidemic if it goes unchecked. However, no one that I have ever heard of has died from the infestation, but it can potentially become an epidemic.
How can an epidemic stop without medical intervention?
An epidemic that is caused by poor water quality or some other environmental cause can be stopped in time if the cause is corrected and remedied. An infectious or viral epidemic needs to have sick people isolated so that the healthy folk do not catch the disease. An example of intervention was for the ebola outbreak, where everyone was told to stay home to help stop the spread.
