We're allowed to address one question per post, so I can
get you started in the right direction.
An epidemic is an
outbreak of a disease in a localized area, usually a city or region. So if flu season
were upon us, and a large number of influenza cases were being reported in New England
or Boston, for example, that would be an epidemic. Epidemics also usually reoccur each
season, in expected numbers and strengths.
A pandemic is a
particular strain of virus that has spread throughout the world. In the year following
World War I, 1919, an influenza outbreak circled the globe in a pandemic that killed
more people than the war itself did. It was a similar strain of flu virus, H1N1 or
Swine flu, that mimicked rather closely the 1919 strain, and that's one reason why
people were afraid it could go pandemic.
Governments in the
industrialized world have low cost, widespread immunization programs, and they
innoculate the most vulnerable, children and the elderly, first.
