CDC guidance on testing and domestic travel
So when should you go for a test? The CDC recommends you get tested three to five days after your trip and stay home for seven days, if you can.
The CDC recommends even if you test negative, you should stay home for the full seven days. A negative test doesn't mean that you weren't exposed. You can still develop COVID-19. Watch for symptoms for 14 days after you travel.

If you do not get tested after travel, the CDC recommends you stay home for 10 days.
If your test is positive, you need to isolate yourself to protect others from getting infected.
