The difference between an epidemic, a pandemic, an endemic and an outbreak?       

  • An EPIDEMIC is a disease that affects a large number of people within a community,
    population, or region.
  • A PANDEMIC is an epidemic that’s spread over multiple countries or continents.
  • ENDEMIC is something that belongs to a particular people or country.
  • An OUTBREAK is a greater-than-anticipated increase in the number of endemic cases. 
    It can also be a single case in a new area.  If it’s not quickly controlled, an outbreak can
    become an epidemic.
