Testing capacity, such a concern for so long, has really begun to expand after hitting a plateau for weeks. Testing nationally on some days has been in the high 300,000s or (on May 17) over 400,000. The issue in some states now is not capacity but actually finding enough people to test.

Scott Gottlieb of the American Enterprise Institute notes that the positivity rate, or percentage of people testing positive, has continued to fall throughout May. In New York City, the country’s epicenter, the positivity rate was below 5 percent as of the middle of the week.

The reopenings could certainly still go awry, but so far there is no clear indication of it. Cases are still falling in Austria, Denmark and Norway, despite those countries being relatively far along on reopening. Denmark has been mystified why it is almost five weeks into reopening and hasn’t yet seen increases in infections.

On Tuesday, Georgia, so widely criticized for its reopening, had its lowest number of Covid-19 patients in the hospital since April 8, when such data began being reported. The number has dropped 12 percent since the week before, and 34 percent since May 1.
