Also: highly recommend (if you can afford it) the Metrix at-home PCR test — accuracy is much higher than the antigen rapid-tests that most people use. Metrix has a reader device and a test kit separate. They're sold out right now because of the surge, but when they come back in stock, that's when to grab one.

If you have to use antigen rapid-tests, then make sure to test 3x, every 2 days, to get that 80% accuracy for a negative test. Positive test accuracy is higher.
