  • Outbreak – (localized epidemic) – more cases of a particular disease than expected in a given area or among a specialized group of people over a particular period of time.
  • Epidemic – large numbers of people over a wide geographic area affected.
  • Pandemic -An epidemic occurring over a very wide area (several countries or continents) and usually affecting a large proportion of the population.
  • Cluster –an aggregation of cases over a particular period esp. cancer & birth defects closely grouped in time and space regardless of whether the number is more than the expected number. (often the expected number of cases is not known.)
