If you have, or are likely to have COVID-19, taking steps to protect yourself and others will help end this pandemic. Because you have a virus that can easily spread to others, it is important that you separate yourself from others and self-isolate. This is also mandated by the County of San Diego Public Health Officer Order.

On this page you will find the Health Officer Order for Isolation of All Persons With or Likely to Have COVID-19 that outlines the legal mandate to isolate, instructions for home isolation, recommendations for close contacts, and resources available.  

Ending Home Isolation

These instructions are for everyone who tests positive for COVID-19, regardless of their vaccination status or previous COVID-19 infection:

  • Stay home and isolate for at least 5* full days after start of symptoms (or after first positive test).
  • Take another COVID-19 test** (either PCR or antigen) on day 5 or later. A negative test is required to end isolation after day 5.
  • If fever is present, continue to isolate until 24 hours after fever resolves.
  • If symptoms, other than fever, are not improving, or your test was positive again, continue to isolate until symptoms resolve or until 10 days after start of symptoms (or after first positive test).
  • Per California Department of Public Health (CDPH) masking guidance, people with COVID-19 should wear a well-fitted face covering around others for a total of 10 days, especially in indoor settings.

* Some people may need to isolate at home longer. This includes people who are 1) severely or critically ill or 2) who have very weak immune systems. Ask your healthcare provider for advice or if you are not sure if this applies to you.

** If you are unable to test or choose not to test again, or if you test positive on Day 5 (or later), isolation can end after Day 10, as long as you have no fever for at least 24 hours without using medications to reduce fever.

Get customized information and guidance with the Centers for Disease Control and Prevention (CDC) COVID-19 Quarantine and Isolation Calculator.

Health care workers and those who live, work, or attend school in certain settings have different isolation recommendations. Please refer to the Health Officer Order for Isolation of All Persons With or Likely to Have COVID-19 for current instructions. 

Information for Your Close Contacts

Please reach out to anyone you have had close contact with to let them know about their exposure to COVID-19 and share the guidance recommended for them.

For close contacts in the general public with no symptoms, regardless of vaccination status (No Quarantine):

  1. Test within 3-5 days after last exposure to someone with COVID-19.

  2. Close contacts should follow guidance for face covering for a total of 10 days, especially in indoor settings and when near those at higher risk for severe COVID-19.

  3. Strongly encouraged to get vaccinated or boosted.

  • What is a close contact?

    A “close contact” is anyone who was exposed to a person infected with COVID-19 while they were infectious.  You are considered to be infectious starting 48 hours/2 days before your symptoms began (for individuals who do not have symptoms, this is 48 hours/2 days before your test was taken) until your isolation period ends.

    A close contact includes:

    Someone sharing the same indoor airspace (i.e., home, clinic waiting room, or airplane), for a cumulative total of 15 minutes or more over a 24 hours (e.g., exposed to three infected individuals, three 5-minute exposures, for a total of 15 minutes), during an infected person's laboratory-confirmed or clinically diagnosed infectious period.


Notify close contacts

      4.  Watch closely for symptoms of COVID-19 such as fever, cough, or shortness of breath.

      5.  If symptoms develop or test result is positive, stay home and follow the Home Isolation Instructions.

Note: If you tested positive for COVID-19 in the past 90 days, you do not need to be tested, quarantined, or excluded from work unless symptoms develop.

For close contacts in high-risk exposures or settings,* visit the Close Contact webpage for additional guidance on work exclusion and quarantine.
