What I can tell you is that the CDC now provides an “infection fatality rate” parameter in it’s planning scenarios. They range the IFR from 0.5% in their best-case scenario to 0.8% in the worst-case scenario.

A new study conducted by researchers at Imperial College London found the COVID-19 infection fatality ratio is about 1.15% of infected people in high-income nations and 0.23% in low-income nations.
The new study confirms that the coronavirus is deadlier for older people, with the risk of death doubling for every eight years of aging and ranging from 0.1% for people under 40 and 5% among people over 80 years old. The disparity between high and low-income nations is due largely to facts that high-income nations tend to have larger number of elderly in their populations whereas low-income nations’ population tend to skew youngers.
