What is Case Fatality Ratio?

The case fatality ratio (CFR) is a measure that describes the severity of a disease by calculating the proportion of individuals diagnosed with the disease who die from it. It is expressed as a percentage and is used to understand the lethality of a disease outbreak. A higher CFR indicates a more deadly disease, while a lower CFR suggests a less severe disease. The CFR is an important metric for public health officials and researchers to assess the impact of a disease and to allocate resources effectively for treatment and prevention.

Example Calculation

Let's assume the following values:

Using the formula:

\[ CFR = \left( \frac{500}{10000} \right) \times 100 = 5.00\% \]

The Case Fatality Ratio (CFR) is 5.00%.
