Which of the Following Shows the Correct Relationship Among the Epidemiology

Question

Which of the following shows the correct relationship among the epidemiology terms listed?
A) prevalence > incidence > mortality
B) incidence > prevalence > mortality
C) mortality > morbidity > prevalence
D) mortality > incidence > prevalence

Accepted Answer

Prevalence is the total number of cases of a disease in a given population at a specific time, incidence refers to the number of new cases that develop in a given period of time, and mortality is the rate of death. Prevalence will generally be higher than incidence because it includes all existing cases, not just new ones. Mortality rates are typically lower than both prevalence and incidence, as not all cases or new cases result in death.
