Lecture 2 Flashcards
Epidemiology
The study of analysis of disease occurrence, distribution, and outcome in a population
Incidence
The rate of occurrence over a specific period of time
Incidence equation
(# of new cases occurring during specific period of time)/(# of people at risk of developing disease during some time period in same population) x 100,000
Prevalence
The current number of all those affected at one point in time
Prevalence Equation
(total # of cases occurring in a population)/(total population) x 100,000
Mortality
the measure of fatality frequency in a population.
it is a crude measurement of how many people have died of a specific illness in a total population.
Mortality Equation
(total # of people who died of specific illness)/ (total population) x 100,000
Case Fatality Ratio (CFR)
a measurement of how many people have died of a specific illness out of all those who have the illness
CFR Equation
(total # of people who died of specific illness)/(total # of people diagnosed with that specific illness) x 100 = __%
