Nursing QUESTION #9156
Question 1
The Case Fatality Rate (CFR) of a disease is best described as:
  • The number of deaths per 1,000 population
  • The proportion of diagnosed cases that die from the disease✔️
  • The probability of dying in a given year
  • The number of deaths per 100,000 live births
Correct Answer Explanation

The Case Fatality Rate (CFR) measures the severity of a disease:

\\text{CFR} = \\frac{\\text{Number of deaths due to disease}}{\\text{Number of confirmed cases of disease}} \\times 100

It is expressed as a percentage. A high CFR indicates a more lethal disease. For example, during the COVID-19 pandemic, CFR was closely monitored to assess disease severity. CFR differs from mortality rate, which uses total population as the denominator.
