Question

An endemic disease is best described as a disease that __________.

Answer 1

An endemic disease is one that is continuously present in the population, often because there is a non-human reservoir for the microbe that causes it. Examples would be malaria (in tropical countries) or histoplasmosis (in America).
An epidemic disease is one that spreads in a sudden, massive surge within a population that is largely without immune protection. An obvious example is influenza, that tends to cause epidemics each time a new virus strain emerges.
An example of a disease that maybe endemic or epidemic is cholera - it can be endemic locally in areas with poor sanitation but can spread violently if sanitation breaks down in disaster areas.
