Which of the following is false with regard to prevalence ?
Correct Answer: It is a rate.
Description: Prevalence:
Prevalence is defined as "the total number of all individuals who have an attribute or disease at a particular time (or during a particular period) divided by the population at risk of having the attribute or disease at this point in time or midway through the period.
Although referred to as a rate, prevalence rate is really a ratio.
Prevalence is of two types :
(a) Point prevalence
(b) Period prevalence
When the term "prevalence rate" is used, without any further qualification, it is taken to mean "point prevalence".
