The US is now mostly reporting over 700,000 tests per day. Based on the experience of other countries, the percent positive needs to be well under 5% to really push down new infections, so the US still needs to increase the number of tests per day significantly (or take actions to push down the number of new infections).
There were 731,700 test results reported over the last 24 hours.
There were 54,184 positive tests.
