April 11 Update: US COVID-19 Test Results: Still Struggling to Test

by Calculated Risk on 4/11/2020 05:04:00 PM

Test-and-trace is a key criterion in starting to reopen the country.   My current guess is test-and-trace will require around 300,000 tests per day at first since the US is far behind the curve.  Some scientists believe we need around 800,000 tests per day.

Note: The Financial Times reports that Germany is doing more than 50,000 tests per day (with about one-fourth of the US population). That would be 200,000 in the US.  I rounded up to 300,000 per day since the US is so behind on testing. But there are recommendations that Germany needs 200,000 tests per day to do test-and-trace.  (800,000 adjusted for population).

Notes: Data for the previous couple of days is updated and revised, so graphs might change.

This is just test results reported daily.

There were 137,181 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 22% (red line).  The US probably needs enough tests to push  the percentage below 5% (probably much lower based on testing in New Zealand).

Test. Test. Test. Protect healthcare workers first!
