Morbidity Frequency Measures
- Several standard measures are used to measure and describe the frequency of disease.
- Each measure has its appropriate uses, depending on the situation and the information available to the epidemiologist.
- The two main types of rates are:
- Incidence rates are the most common way of measuring and comparing the frequency of disease in populations.
- Incidence is a measure of risk.
- When Population A has a higher incidence of a disease than Population B, we can say that Population A has a higher risk of developing the disease than Population B. If it is a lot higher, we could say that Population A is a high-risk group for that disease.
