Trainer Attachment 13B: Definition of rates

Incidence Rate	- In surveillance feedback is a report that interprets the data collected and is distributed to those who have collected it. The number of new cases of a specified disease diagnosed or reported during a defined period of time as the numerator, and the number of persons in a stated population in which they occur as the denominator. A rate is the average risk of disease in that time interval.
Mortality rate	- A rate calculated in the same way as an incidence rate using as the numerator the number of deaths occurring in the population during the stated period of time.
Prevalence Rate	- The numerator is the number of persons sick or portraying a certain condition in a stated population, at a particular time, regardless of when that illness or condition began, the denominator is the number of persons in that population.
