MOVING TO FRONT FROM MARCH 20--SEE MARCH 26 UPDATE
The University of Washington has led the way in COVID-19 testing, and in the midst of the country's worst initial outbreak. Their daily tracker of test results (scroll down to see the chart) suggests positive results are not increasing and may even be declining in just the last couple of days. Perhaps this is due to strict containtment measures in the last few weeks there, or something else. Thoughts from knowledgeable readers?
UPDATE: Statistician Nate Silver on the Washington data.
MARCH 26 UPDATE: It looks like the rate of new confirmed infections in Washington has indeed stabilized, a good bit of evidence for the value of social distancing and business closures.
