The US is now conducting over 500,000 tests per day, and that might be enough to allow test-and-trace in some areas. 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.

According to Dr. Jha of Harvard's Global Health Institute, the US might need more than 900,000 tests per day.

There were 539,333 test results reported over the last 24 hours.

There were 42,161 positive tests. This is the third consecutive day with over 40,000 positive cases.
