In epidemiology, the case-fatality rate (sometimes called case-fatality risk or case-fatality rate) is the ratio of the number of people who die from a disease to the total number of people diagnosed with the disease in a given period of time.

How to calculate the death rate of COVID-19 infection?

This indicator is calculated by dividing the total number of people who have died from the disease by the total number of people infected; therefore, compared to the CFR, the IFR includes asymptomatic and undiagnosed infections and reported cases.

However, estimates for both COVID-19 and influenza viruses are strongly contextual and time-specific, making direct comparisons more difficult.
