With the increasing prevalence of the Delta variant, vaccinated persons also need to be aware of what precautions to take after being exposed to COVID-19. Official CDC guidance does not require fully vaccinated persons to quarantine after exposure but recommends getting a COVID-19 test 3-5 days after exposure. Even if you are not experiencing symptoms, you should wear a mask indoors for 14 days after exposure to prevent spreading the virus.

When to Get Tested for COVID-19 After Exposure

If you were recently exposed to COVID-19, it is likely you were exposed to the Delta variant. You will most likely test positive within 4 days after being exposed to the Delta variant, but a negative test does not necessarily mean you are not infected. If you are exposed and test negative, you should obtain a second test in the next few days.
