How many Americans have been tested for coronavirus?

More than 500 people in the U.S. have tested positive so far, and Vice President Mike Pence said officials expect that number to increase as the country dramatically scales up its testing capacity.

The Trump administration has faced scrutiny for a delay in widespread testing for the virus due to problems with the CDC’s initial diagnostic test. Azar told reporters the administration has sent out over 1 million tests from CDC and two contractors, and there’s another 2.1 million available and awaiting shipment.

He added that commercial labs will soon contribute to a dramatic increase in available tests as well.
