In these moments, when the good of all hinges on the sacrifices of many, clear coordination matters—the fourth urgent need. The importance of social distancing must be impressed upon a public who must also be reassured and informed. Instead, Trump has repeatedly played down the problem, telling America that “we have it very well under control” when we do not, and that cases were “going to be down to close to zero” when they were rising. In some cases, as with his claims about ubiquitous testing, his misleading gaffes have deepened the crisis. He has even touted unproven medications…

A recent analysis from the University of Pennsylvania estimated that even if social-distancing measures can reduce infection rates by 95 percent, 960,000 Americans will still need intensive care. There are only about 180,000 ventilators in the U.S. and, more pertinently, only enough respiratory therapists and critical-care staff to safely look after 100,000 ventilated patients. Abandoning social distancing would be foolish. Abandoning it now, when tests and protective equipment are still scarce, would be catastrophic.

If Trump stays the course, if Americans adhere to social distancing, if testing can be rolled out, and if enough masks can be produced, there is a chance that the country can still avert the worst predictions about COVID-19, and at least temporarily bring the pandemic under control. No one knows how long that will take, but it won’t be quick. “It could be anywhere from four to six weeks to up to three months,” Fauci said, “but I don’t have great confidence in that range.”
