The prevalence rate is the fraction or proportion of a group possessing a disease or condition at a specific time, whereas the incidence rate is the fraction or proportion of a group initially free of a disease or condition that develops the disease or condition over a period of time. By calculating and comparing rates, epidemiologists can determine the strength of the association between risk factors and the health problem being studied.
