pandemic 和epidemic有什么区别

pandemic是指疾病迅速蔓延、涉及地域广，在短期内可越过省界、国界、甚至洲界的情况。如流行性感冒和霍乱，历史上曾发生过多次世界性大流行。
主要侧重其流行程度
epidemic侧重疾病的传染性很大

pandemic是指大型的，造成严重后果的。很难控制的。全世界性的疾病。
epidemic指有传染性的疾病

Epidemic：An epidemic occurs when the incidence rate (i.e. new cases in a given human population, during a given period) of a certain disease substantially exceeds what is "expected," based on recent experience.
Pandemic： is an epidemic of an infectious disease that spreads through human populations across a large region, like a continent.
【Comparison】
Epidemic ：Disease outbreak that is concentrated in a particular region。
Pandemic：Disease outbreak that occurs over a wide geographic area and affects a very high proportion of the population.
故，Pandemic可理解为一种流行非常广的Epidemic。
