Epidemiology has a variety of sub-disciplines. Each of these sub-disciplines has different measures they use to determine the severity of the communicability of various diseases. The two classic measures are incidence and prevalence. However, there are other measures of disease measurement, which can include:
Morbidity
Incidence
Cumulative Incidence
Incidence Density
Incidence Rate
Prevalence
Period Prevalence
Point Prevalence
Mortality
Case Fatality Rate 
Proportionate Mortality Rate
Age Specific Death Rate
Age-Adjusted Rate
Direct Age Adjustment
Indirect Age Adjustment
Years of Potential Life Lost
Outbreak Specific Calculations
R0 (R naught or Reproductive Ratio)
Attack Rate (usually used for foodborne pathogens)
Secondary Attack Rate (used for any communicable disease to describe the percentage of secondary cases)
Discussion:
In this discussion, you will select a disease with which you are interested in. You will need to search the Morbidity and Mortality Week Report, Emerging Infectious Disease Journal, and Preventing Chronic Diseases Journal. Your response should range from 300 – 500 words and discuss the disease you selected and at least two measures from the Morbidity and Mortality section of this prompt. In your discussion, you should explain why that measure is used and what some of the limitations of that measure is regarding your disease.
