What is the formula used to calculate the prevalence rate of a sexually transmitted disease?

• A. (# of people infected / total # of people) x 100
• B. (# of disease occurrences / total population) x 100
• C. (# of recovered patients / total # of cases) x 100
• D. (total population / # of new infections) x 100

Answer: (A)

The formula for calculating the prevalence rate of a sexually transmitted disease is derived from the concept of measuring the proportion of a population that is affected by the disease at a given time. This is expressed as the number of people currently infected divided by the total number of people in the population, multiplied by 100 to convert it into a percentage. Using this formula, you assess how widespread a sexually transmitted disease is within a defined population. The prevalence rate provides essential information about the burden of the disease, which can be critical for public health planning and resource allocation. The other options do not accurately reflect the definition of prevalence. For example, one option refers to disease occurrences without specifying whether they are current cases or new cases, which can lead to confusion regarding whether it represents prevalence or incidence. Another option involves recovered patients rather than current infections, which is not relevant to calculating prevalence. Finally, one could interpret another option as referring to a ratio that does not align with the standard definitions and calculations used in epidemiology.
