fatality rate

The fatality rate is a measurement that shows how many people die from a specific cause compared to the total number of people affected, usually expressed as a percentage. For example, if an illness causes 100 people to become seriously ill and 10 of them die, the fatality rate is 10%. It helps assess how dangerous a disease or event is, indicating the likelihood of death among those impacted. This rate is useful for understanding risk levels and guiding health responses and safety measures.
