In addition to having enough tests for test-and-trace, we also need people to conduct contact tracing. There is a great website that tracks the progress of each towards test-and-trace. The website also has resources on how to implement test-and-trace. This includes software, training resources, a calculator for how many people to hire and more.
My state (California) now has 3,800 contact tracers. That is still too few, but a start!
In late April, Dr. Fauci said the US might be able to test 400,000 to 600,000 people per day sometime in May, and testing is below that range. There might be enough to allow test-and-trace in some areas. However, the US might need more than 900,000 tests per day according to Dr. Jha of Harvard’s Global Health Institute.
There were 285,440 test results reported over the last 24 hours.
This data is from the COVID Tracking Project.
The percent positive over the last 24 hours was 6.5% (red line). The US probably needs enough tests to keep the percentage positive well below 5%. (probably much lower based on testing in New Zealand).
