The coronavirus is spreading at dangerous levels across much of the United States, and public health experts are demanding a dramatic reset in the national response, one that recognizes that the crisis is intensifying and that current piecemeal strategies aren’t working.

This is a new phase of the pandemic, one no longer built around local or regional clusters and hot spots. It comes at an unnerving moment in which the economy suffered its worst collapse since the Great Depression, schools are rapidly canceling plans for in-person instruction and Congress has failed to pass a new emergency relief package. President Trump continues to promote fringe science, the daily death toll keeps climbing and the human cost of the virus in America has just passed 150,000 lives.

“Unlike many countries in the world, the United States is not currently on course to get control of this epidemic. It’s time to reset,” declared a report released this week by Johns Hopkins University.

Another report from the Association of American Medical Colleges offered a similarly blunt message: “If the nation does not change its course — and soon — deaths in the United States could be well into the multiple hundreds of thousands.”
