Info Edit

    Usually given as a percentage, HIV prevalence quantifies the proportion of individuals in a population who have HIV at a specific point in time. The terms prevalence and incidence should not be confused. Incidence only applies to the number of new cases, while the term prevalence applies to all cases, old and new.
