Kent Emmons: Columbia University says that nationwide, 61 percent of deaths and 55 percent of infections could have been avoided early on. What’s this all about?

Barry Nussbaum: It has to do with the fact that we in the United States didn’t get notice from the origin of this virus, i.e., Wuhan, China, that it was fully communicable. It could spread from person to person. And it was killing people. And so we delayed our nationwide responses because of that. They’re now saying, had we just known a week or two earlier, more than half the people died would not have died. And more than half the cases would not have happened because the shut down would have happened a week or two earlier. We should blame China.
