cumulative incidence
person-time
attack rate
prevalence
The number of affected persons present in the population at a specific time divided by the number
of persons in the population at that time.
When different individuals are observed for different lengths of time, we calculate an incidence
rate (also called incidence density) in which the denominator consists of the sum of the units
of time that each individual was at risk and was observed.
The ongoing systematic collection, analysis, and interpretation of health data essential to the
planning, implementation, and evaluation of public health practice closely integrated with the
timely dissemination of these data to those who need to know
The incidence calculated using a period of time during which all of the individuals in the population
are considered to be at risk for the outcome
The number of people who were exposed and became ill over the total number of people who
were exposed. This is not truly a rate but a proportion.
The number of cases of a disease that occur during a specified period of time in a population at
risk for developing the disease.
