Case fatality rate (CFR) is a massively flawed measure. It’s bounced around between 5% and 3% from month to month. The actual number to be concerned about is the infection fatality rate (IFR), which gives you an actual risk of death from infection that doesn’t depend on how many cases get missed.
The IFR has been estimated between 0.64% and 0.66% for months now. The CDC’s best estimate is 0.65% (https://www.cdc.gov/coronavirus/2019-ncov/hcp/planning-scenarios.html).
Even with the CFR calculation, I have no trust in the numerator given the incentives to code deaths as Covid.
