Which measure indicates existing cases at a given point in time?

Explanation:
Prevalence is the measure that represents the number or proportion of people who already have a condition at a specific point in time. It provides a snapshot of the existing disease burden in a population, which is different from incidence, the rate of new cases over a period. Prognosis refers to the expected course or outcome for an individual, and etiology concerns the cause of the disease. So, to indicate existing cases at a given moment, prevalence is the best measure.
