Quizplus · Accepted Answer

Prevalence refers to the total number of cases of a disease or condition within a particular time period, while incidence refers to the number of new cases that develop within a specific period of time. Therefore, Option C is correct as it explains that prevalence is the total number of cases, while incidence is the total number of new cases within a period of time. Option A is incorrect as it states that prevalence is the number of new cases, which is incorrect. Option B is incorrect as it suggests that prevalence only counts new cases over a period, but it actually includes both new and existing cases. Option D is incorrect as it incorrectly suggests that prevalence and incidence only apply to psychiatric or physical illness.
