There is no historical comparison for what our country is going through.

Medically? We’re rivaling the 1918 Spanish flu epidemic. Economically? We’re seeing unemployment that could look like the Great Depression. Critical supplies? We need to produce more, faster, than any time since World War II.

Every domino is falling at once. And they’re falling hardest here in New York City.

On Friday we hit a painful milestone, surpassing 50,000 confirmed cases of the coronavirus. We’ve lost 1,562 New Yorkers. One of every four cases in the United States is a New York City resident.

There is only one way to get New York City and every city the medical personnel we need: The federal government should enlist every available private doctor, nurse and essential health care worker to fight in this war.

It would be a remarkable step. But these are remarkable times.

We’re already trying unimaginable things. We started this crisis with a little under 20,000 hospital beds — and want to quadruple that by the end of April. We’re gathering ventilators and equipment from every possible source, and I’ve called on President Trump to use the Defense Production Act to its fullest extent.
