Calculate Prevalence Rate



Formula

The formula to calculate the Prevalence Rate (P) is:

\[ P = \left( \frac{TC}{TP} \right) \times 100 \]

What is Prevalence?

Prevalence is defined as the portion or percentage of a population that has contracted a certain disease. It is calculated by dividing the number of cases by the population size, then multiplying the result by 100. This measure helps in understanding the extent of a disease within a population at a given time.

Example Calculation

Let's assume the following values:

Using the formula to calculate the Prevalence Rate:

\[ P = \left( \frac{500}{50000} \right) \times 100 = 1\% \]

The Prevalence Rate is 1%.
