It’s Time to Start Testing Coronavirus Immunity

President Donald Trump isn’t the only one who wants to reopen the country as quickly as possible as it deals with the coronavirus pandemic. Everyone wants that — we want to get businesses and schools up and running again, and we want to get back to our normal lives, which include seeing friends and colleagues in person instead of through Zoom and Skype.

But unlike the president, most people are aware of how dangerous it would be to try to return to normal too soon. In a country of 330 million people, fewer than 1 million will have been tested by the end of this month. (As of Thursday, 519,000 people had been tested, including 122,000 in New York State, according to the Covid-19 Testing Project.)
