Final answer:
The number of patients newly diagnosed with diabetes in a year exemplifies the incidence of disease, which is a measure of the number of new cases in a population during a set time period.
Step-by-step explanation:
The number of patients newly diagnosed with diabetes in a year is an example of the incidence of disease. Incidence refers to the number of new cases of a disease that occur in a specific time period within a given population. It is a measure used by epidemiologists to assess the risk factors and the spread of a disease. Incidence differs from prevalence, which accounts for both new and existing cases of a disease within a population over time. By tracking these new cases, we can better understand how rapidly a disease is spreading or how effective prevention and control measures are.
Prevalence is a measure of how common a disease is at any given time and includes both new and existing cases. It provides an indication of the overall health burden of a disease within a population. On the other hand, morbidity simply refers to the state of having a disease, and morbidity rates detail the number of cases of a disease in a population. Mortality is the occurrence of death within a population, and mortality rates express the number of deaths due to a specific disease.
