How do health officials decide whether to declare an outbreak, epidemic, or a pandemic?
Public health officials differentiate between an outbreak, an epidemic, and a pandemic as follows:
• An outbreak is a sudden rise in the incidence of a disease.
• An epidemic affects an atypically large number of individuals within a population, community, or region at the same time.
• A pandemic occurs over a wide geographic area and affects an exceptionally high proportion of the population. Influenza pandemics tend to occur when disease-causing organisms that typically affect only animals adapt and infect humans, then further adapt so they can pass easily from human to human. The flu pandemic of 1918–1919 claimed half a million lives.
