The formula to calculate the period prevalence rate is:
\[ PP = \frac{C}{P} \times 100 \]
Where:
Period prevalence refers to the proportion of a population that is affected by a particular disease or condition at any point during a specified time period. It is a measure of how widespread the condition is within the population at risk. This metric is useful for public health officials to understand the burden of a health problem within a community and to allocate resources accordingly.
Let's assume the following values:
Using the formula to calculate the period prevalence rate:
\[ PP = \frac{500}{50000} \times 100 = 1\% \]
The period prevalence rate is 1%.
