Prevalence includes which of the following?

Explanation:
Prevalence measures how widespread a disease is at a specific time by counting all people who currently have the condition, regardless of when it started. That means it includes those who were diagnosed recently (new cases) and those who have had it for some time (existing cases). So it reflects both new and existing cases. Incidence, in contrast, counts only new diagnoses over a period. This makes prevalence the best choice for describing the total burden at a moment in time.
