Prevalence is the measure of existing disease in a population at a particular time.Because we do not have baseline data,we have no way to conclude that this is an epidemic with higher-than-normal results from the screening.Incidence refers to new cases,whereas prevalence means all cases.We don't know whether the finding represents the first time a woman was told she had an STI or whether she had previously been diagnosed with the problem.Therefore,we can't say whether these are new cases (incidence),but the results do represent all cases (prevalence).Risk is the probability of developing an STI,but no risk factors are discussed.
