For people <70, the death rate (IFR) of COVID-19 is similar to that of a seasonal flu.
How does the death rate of the coronavirus (SARS-CoV-2) compare to that of a regular, seasonal flu? Is there a significant difference?
According to leading epidemiologist Dr. John Ioannidis of Stanford University, 0.05% to 1% is a reasonable range for what the data tell us now for the infection fatality rate, with a median of about 0.25%. The death rate in a given country depends a lot on the age-structure, who are the people infected, and how they are managed. For people younger than 45, the infection fatality rate is almost 0%. For 45 to 70, it is probably about 0.05-0.3%. For those above 70, it escalates substantially, to 1% or higher for those over 85. For frail, debilitated elderly people with multiple health problems who are infected in nursing homes, it can go up to 25% during major outbreaks in these facilities.
