try again. to find the percentage, you have to use the total number of those infected, not recovered.
Latest Johns Hopkins numbers. Flawed, but all we have.
AP: "Worldwide, confirmed infections rose past 1.1 million and deaths exceeded 63,000 ...
"At the same time, more than 233,000 people have recovered from the virus ..."
233,000 recovered. 63,000 died. That's a total of 296,000 'completed' cases.
So, if the virus went away right now, the death rate would be 63,000÷296,000 = 21%. One fifth. The rates of 1%, 3% and so on are interim, while the plague runs. Isn't the one that will matter the rate calculated when it's over?
