Quarantine / Isolation Protocol (Updated 8/22/2022)
Start Precaution Immediately
Wear a mask as soon as you find out you were exposed
Start counting from Day 1
Day 0 is the day of your last exposure to someone with COVID-19
Day 1 is the first full day after your last exposure
Continue Precautions - 10 Full Days
You can still develop COVID-19 up to 10 days after you have been exposed
Do not go places where you are unable to wear a mask, including travel and public transportation settings.
Watch for symptoms
fever (100.4°F or greater)
shortness of breath
If you develop symptoms
If your test result is positive, follow the isolation recommendations.
Get Tested - Day 6
Test even if you don’t develop symptoms.
If you already had COVID-19 within the past 90 days, see specific testing recommendations.
IF YOU TEST
Continue taking precautions through day 10
Wear a high-quality mask when around others at home and indoors in public
You can still develop COVID-19 up to 10 days after you have been exposed.
*About negative test results
As noted in the Food and Drug Administration labeling for authorized over-the-counter antigen tests, negative test results do not rule out SARS-CoV-2 infection and should not be used as the sole basis for treatment or patient management decisions, including infection control decisions.
IF YOU TEST
When you have COVID-19, isolation is counted in days, as follows:
If you had no symptoms
Day 0 is the day you were tested (not the day you received your positive test result)
Day 1 is the first full day following the day you were tested
If you develop symptoms within 10 days of when you were tested, the clock restarts at day 0 on the day of symptom onset
If you had symptoms
Day 0 of isolation is the day of symptom onset, regardless of when you tested positive
Day 1 is the first full day after the day your symptoms started
Regardless of when you end isolation, avoid being around people who are more likely to get very sick from COVID-19 until at least day 11. Remember to wear a high-quality mask when indoors around others at home and in public and not go places where you are unable to wear a mask until you are able to discontinue masking (see below), including public transportation and travel settings.
Loss of taste and smell may persist for weeks or months after recovery and need not delay the end of isolation.
Removing Your Mask
After you have ended isolation, when you are feeling better (no fever without the use of fever-reducing medications and symptoms improving),
Wear your mask through day 10.
If you have access to antigen tests, you should consider using them. With two sequential negative tests 48 hours apart, you may remove your mask sooner than day 10.
Note: If your antigen test results1 are positive, you may still be infectious. You should continue wearing a mask and wait at least 48 hours before taking another test. Continue taking antigen tests at least 48 hours apart until you have two sequential negative results. This may mean you need to continue wearing a mask and testing beyond day 10.
After you have ended isolation, if your COVID-19 symptoms recur or worsen, restart your isolation at day 0. Talk to a healthcare provider if you have questions about your symptoms or when to end isolation.
