How is prevalence defined?

Prevalence is a statistical measure that refers to the number or proportion of individuals in a population who have a specific condition or disease at a given point in time. It is often used in public health research to describe the extent or burden of a particular health issue in a population. Prevalence is typically expressed as a percentage or a rate and is calculated by dividing the number of individuals with the condition by the total population size. This measure helps in understanding the magnitude of the problem and is used to inform healthcare planning, resource allocation, and policy decisions.
