Case Fatality Rate (CFR) is a measure of the severity of a disease. It is correctly calculated as:
- A Number of deaths from the disease divided by number of diagnosed cases of that disease ✓
- B Number of deaths from the disease divided by total population at risk
- C Number of new cases of the disease divided by total population
- D Number of deaths from the disease divided by number of recoveries
Correct answer: A. Number of deaths from the disease divided by number of diagnosed cases of that disease
Explanation
CFR is the proportion of persons diagnosed with a disease who die from that disease within a specified time. It measures disease lethality and is calculated as deaths divided by cases, usually expressed as a percentage. It is not a population-based rate but a measure among cases.
