"The CDC's overall IFR estimate implies that COVID-19, while not nearly as lethal as many people initially feared, is about six times as deadly as the seasonal flu. But as with the flu, the risk is highest for the elderly, and the difference in the case of COVID-19 is huge. The estimated IFR for people in their 70s is 11 times the rate for 50-to-69-year-olds, 270 times the rate for 20-to-49-year-olds, and 1,800 times the rate for people younger than 20. In the latter two groups, the estimated IFR is lower than the overall IFR for the seasonal flu."
"The CDC's latest death counts indicate that the crude case fatality rate is around 28 percent for patients 85 or older and 18 percent for 75-to-84-year-olds. That rate falls to about 8 percent for 65-to-74-year-olds, 2 percent for 50-to-64-year-olds, 0.6 percent for patients in their 40s, 0.2 percent for patients in their 30s, 0.06 percent for patients in their late teens and early 20s, 0.02 percent for 5-to-17-year-olds, and 0.04 percent for children 4 and younger."

It does vary from country to country. In the Netherlands fewer people have died of Covid thus far, than died during the flu of 2018.
