Disease occurrence can be measured as prevalence or incidence. Which measure is better suited for the evaluation of preventive programs? A) cumulative incidence B) prevalence C) A and C D) incidence rate E) A and B
Homework Answers
Answer
D) Incidence rate
Explanation :Incidence rate is more useful in measuring effect of preventive programs.
prevalence is a composite measure of the incidence rate and the mean disease duration. Prevention should decrease new occurrence of disease, which should result in decrease in the incidence rate. This does not necessarily result in prevalence as soon as incidence, as a large pool of people who already have the disease of interest can keep existing.

Define incidence and prevalence of disease. Name a microbial disease for which the numerical values of annual incidence and annual prevalence are likely similar and name another microbial disease for which the numerical values of annual incidence and annual prevalence are likely quite different; explain why this is the case for both diseases.

Incidence and prevalence rates can also be used to compare the rates of disease across different...
Incidence and prevalence rates can also be used to compare the rates of disease across different settings (places), people, or time. We therefore need measures of comparison. The ratio of two measures of disease frequency is called the relative risk. The difference between two measures of disease frequency is called the risk difference, or rate difference. In some cases, it involves a measure in an exposed group (or groups) and a measure in an unexposed or comparison group. In other...
