The death rate depends on the state but the fact it is it is dropping. North Carolina is around 1.5%. It’s falling because they are testing asymptomatic people now. It could drop below 1% after schools start back up and all the college students get tested.
Since we do not test everyone, and I am not advocating that we do, there is only a statistical guess as to how many have been infected, but even the CDC numbers have previously stated that the death rate is no higher than the flu and probably about the flu rate.
