Epidemiologists use various measures to describe the occurrence of disease and health outcomes:
Incidence: The number of new cases of a disease in a specific population over a given time period. Prevalence: The total number of cases of a disease in a population at a specific point in time. Mortality Rate: The number of deaths due to a particular cause in a specific population over a given time period. Risk Ratio: A measure of the association between exposure and outcome, comparing the risk in the exposed group to the risk in the unexposed group.
