Quarantine and Isolation Guidance

If You've Tested Positive for COVID-19: Isolation

Because of the large number of positive COVID-19 cases in our community, those with a positive COVID test may not hear from the Public Health department.

Step 1: If you have tested positive for COVID-19, you need to isolate immediately regardless of your vaccination status.


Step 2: Identify your close contacts. Share the Quarantine Instructions with all your close contacts.

  • How to identify close contacts
    • You are considered infectious two days before your symptoms started. If you are asymptomatic, you are considered infectious two days before the day you took your test. You are considered infectious until your isolation ends.
    • Close contacts are everyone who was within 6 feet of you for more than 15 minutes while you were infectious. The 15 minutes are cumulative over 24 hours, so if you are close to someone for 5 minutes three times in one day while infectious, they are a close contact.

Let your employer know if you were infectious while at work. Employers can find resources for workplace exposures here

If positive for COVID, you do not need to get tested again in order to come out of your isolation. Because dead virus particles remain in your body even after you are no longer infectious, the COVID test may still come back as positive. This means the test can’t determine when you are no longer contagious. When your isolation period is over, you are no longer considered contagious. 

If You Were Exposed to COVID-19: Quarantine

If you were a close contact of someone who tested positive for COVID-19, you must follow the Quarantine Guidance (Instrucciones para estar en cuarentena).

A "close contact" is defined by the CDC as someone who was within 6 feet of an infected person for a total of 15 minutes or more over a 24-hour period starting from 2 days before illness onset (or, for asymptomatic patients, 2 days prior to their test) until the time the patient is isolated.  

For more information, see this Guide to Quarantine and Isolation (CDPH).
