COVID Stats - can you make sense of this?
There is an article in the Wall Street Journal written by a Johns Hopkins doctor. He feels we are closer to herd immunity than the CDC and others are saying, and he projects Covid will be mostly gone by April, allowing Americans to resume normal life. But he writes this below, which I don't understand:
Covid-19 deaths in the U.S. would also suggest much broader immunity than recognized. About 1 in 600 Americans has died of Covid-19, which translates to a population fatality rate of about 0.15%. The Covid-19 infection fatality rate is about 0.23%. These numbers indicate that roughly two-thirds of the U.S. population has had the infection.
How is he computing that?
