in Wall Street Journal, by Marty Makary

«The article’s claim that the U.S. is near herd immunity rests on two numbers: 1) the detection of infections by testing (claimed to be 10 – 25 percent) and 2) the infection fatality rate (claimed to be 0.23 percent). Using the same number of deaths as the author indicates that 0.15%/0.6% = 25% of the U.S. population has been infected, rather than two-thirds as the author claims. Thus, the author’s argument that 55 – 66 percent of the U.S. population has already been infected and has immunity is not supported by available data.»
