How to Calculate Prevalence Rate of Disease - Definition, Formula, Example

Definition:

Prevalence is a term which is used to denote the measurements of disease frequency. Prevalence of a disease is the proportion of population affected by a specific disease at a particular time.This tutorial explains you how to calculate the Prevalence rate of Disease.

Formula:

Prevalence Rate of Disease = (n / Total population) x 10 n Where n - All new & preexisting cases of specific disease
Example:

Consider that a hospital has 2 all new & preexisting cases of specific disease and total population 4. Calculate the Prevalence Rate of Disease.

Given,

All new & preexisting cases of specific disease (n) = 2 Total population = 4

To find,

Prevalence Rate of Disease

Solution:
Prevalence Rate of Disease = (n / Total population) x 10 n
= (2 / 4) x 10 2
= 0.5 x 100
= 50
