If they aren't clinically sick they won't even be tested. And if they present with ALL the symptoms, they will have to wait until a test kit becomes available.
So far a whopping 415 Americans have been tested.
We don't seem to have any more test kits.
If we had more, there would be 546 tests completed. (435 congressmen, 100 senators, 9 supreme court justices, the president, and the vice president)
These are confirmed infections.
