Is Ebola a epidemic or pandemic?
Ebola has so far only affected African countries and occasional cases outside of the continent have been rapidly contained. But the virus could mutate to spread more easily between people, making it more of a pandemic threat.
Which diseases are endemic?
Examples of endemic diseases include chicken pox that occurs at a predictable rate among young school children in the United States and malaria in some areas of Africa. The disease is present in a community at all times but in relatively low frequency.

For example, in meningococcal infections, an attack rate in excess of 15 cases per 100,000 people for two consecutive weeks is considered an epidemic. Epidemics of infectious disease are generally caused by several factors including a change in the ecology of the host population, a genetic change in the pathogen reservoir or the introduction of an emerging pathogen to a hos
