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.
an epidemic
An outbreak of an infectious disease is called an epidemic if a lot of people in one area become infected. But if the disease is very widespread, international and many people need treatment, it is called a pandemic.
EPIDEMIC (noun)The noun EPIDEMIC has 1 sense:1. a widespread outbreak of an infectious disease; many people are infected at the same time• EPIDEMIC (adjective)The adjective EPIDEMIC has 1 sense:1. (especially of medicine) of disease or anything resembling a disease; attacking or affecting many individuals in a community or a population simultaneousl
An epidemic disease that covers a widespread area such as a country or continent and lots of people get the disease.
a reactivation of an earlier infection with epidemic typhus. It affects people years after they have completely recovered from epidemic typhus.
An epidemic occurs when the rate of a disease (incidence) rises above the prevalence of a disease in a certain area. I.e. if you have 20 cases of TB reported every year for every 1000 people, it would be an epidemic if it raised to 30.
The terms used are epidemic or pandemic if the disease suddenly appears and spreads throughout the population (example plague or influenza). However some diseases (dental caries, arthritis, malaria, etc.) are wide spread and always present in many people. These are called endemic diseases.
an epidemic
An epidemic is when new cases of a given disease spread throughout a given population at a rate that is greater than would normally be expected. The disease in question doesn't have to be contagious to fit the definition of epidemic. As far as a pandemic goes, you might say it is an epidemic on steroids. By that I mean, that when an epidemic spreads over a large area--over a continent, several continents, or even global--it becomes a pandemic. If the number of people who are becoming sick with the epidemic disease is stable (meaning the disease is spreading over a great distance, but the number of people who are sick at any given time is remaining relatively the same), then it is not a pandemic. Finally, for a disease to meet pandemic criteria, it must be infectious.

You put this in taxonomy, so i guess you were asking for a binomial nomenclature? Epidemics are natural disasters, not animals...so the scientific name for epidemic is therefore: an epidemic.
