Throughout history there have been outbreaks of infectious diseases. The well-known plague epidemic (Black Death) was a devastating global epidemic of bubonic plague that struck Europe and Asia in the mid-1300s, wiping out an estimated one-third of the population. Disease outbreaks, when large in scope, have been referred to as epidemics. More recently, epidemics that have involved or might involve the global population have been labelled as pandemics.

When does an epidemic become a pandemic? There is no single accepted definition of the term pandemic (ref: Journal of Infectious Diseases, Vol. 200:7, 1 October 2009). Some considerations for labelling an outbreak as a pandemic include outbreaks of diseases:

  • that extend over large geographic areas, e.g., influenza, HIV/AIDS
  • that have high attack rates and explosiveness, e.g., common-source acquisition and highly contagious diseases with short incubation periods
  • that affect populations with minimal population immunity
  • that involve a new or novel version of an infectious agent – the term pandemic has been used most commonly to describe diseases that are new, or at least associated with novel variants of existing organisms, e.g., influenza.
  • that are highly contagious. Many, if not most, infectious diseases considered to be pandemic by public health officials are contagious from person to person
  • that have severe health consequences. The term pandemic has been applied to severe or fatal diseases

For purposes of this paper, a pandemic is an epidemic occurring worldwide, or over a very wide area, crossing international boundaries and usually affecting a large number of people.(1)
