Question

Quizplus · Accepted Answer

Incidence measures the number of new cases of a disease that develop in a population during a specific time period, while prevalence measures the total number of cases (both new and existing) at a particular point in time. A prevalent case includes individuals who were diagnosed before the start of the study period and may not be counted in the incidence measure if they were diagnosed earlier. Therefore, incidence is not always higher than prevalence; they measure different aspects of disease frequency.
