prevalence
total number of cases of disease occurring within a pop at any one given point in time
how do you calculate incidence rate?
( number of new cases of a disease within a pop in a given time period / number of persons exposed to risk of developing the disease in the same time period ) x 1000
difference between prevalence and incidence
prevalence; who has it and who doesnt at a given time vs incidence only looking at new cases
in a steady state situation; prevalence is equal to
incidence x duration of disease
What does epidemic imply?
a larger number of cases over a wide geographic area
What does the term cluster refer to?
an aggragate of cases in a given area over a particular period in time without regard the whether the number of cases is greater than expected
common source
everyone's exposed to same thing
point source
the exposure occurs all at once
intermittent or continuous
the exposure continues over a period of time
propagated
disease spreads gradually from person to person
primary case
person initially infected from a point source
secondary cases
person to person transmission from primary cases to others

Holoendemic (notes)
endemic in most of the children in a population, with the adults in the same population being less often affected
Epidemic (notes)
a disease occuring suddenly in numbers far exceeding those attributable to endemic disease; occuring suddenly in numbers clearly in access of normal expectancy

of, or related to a rapidly spreading and widely diffused disease affecting large numbers of animals in a given region.
Primary level of prevention
