White House coronavirus adviser Scott Atlas is urging President Donald Trump to allow the virus to spread through the country’s population in order to build “herd immunity,” and the administration has already taken steps in that direction, according to a Monday report from The Washington Post. Public health experts inside and outside the government warned the Post that a “herd immunity” strategy may prove ultimately ineffective if people who recover from COVID-19 can become reinfected. And it could result in a staggering death toll -- a Post analysis found that “it may require 2.13 million deaths to reach a 65 percent threshold of herd immunity.”
