Isolation and Quarantine Recommendations
for the General Public

All persons with COVID-19 symptoms, regardless of vaccination status or previous infection, should:
  • Self-Isolate - Everyone, regardless of vaccination status, previous infection, or lack of symptoms. Isolation Graphic - English
  • Recommendation:
    • Stay home (PDF) for at least 5 days after start of symptoms (or after date of first positive test if no symptoms).
    • Isolation can end after day 5 if symptoms are not present or are resolving and a diagnostic specimen collected on Day 5 or later tests negative.
    • If unable to test, choosing not to test, or testing positive on Day 5 (or later), isolation can end after Day 10 if fever-free for 24 hours without the use of fever-reducing medications.
    • If fever is present, isolation should be continued until 24 hours after fever resolves.
    • If symptoms, other than fever, are not resolving, continue to isolate until symptoms are resolving or until after Day 10.
    • Per CDPH masking guidance, infected persons should wear a well-fitting mask around others for a total of 10 days, especially in indoor settings (see masking section below for additional information).


Asymptomatic Persons Who are Exposed to Someone with COVID-19:
  • No Quarantine - Everyone, regardless of vaccination status.
  • Recommendation:
    • Test within 3-5 days after last exposure.
    • Per CDPH masking guidance, close contacts should wear a well-fitting mask around others for a total of 10 days, especially in indoor settings and when near those at higher risk for severe COVID-19 disease (see masking section below for additional information).
    • Strongly encouraged to get vaccinated or boosted.
    • If symptoms develop, test and stay home (see earlier section on symptomatic persons), AND
    • If test result is positive, follow isolation recommendations above.


All close contacts, whether quarantined or not:

Should consider testing as soon as possible to determine infection status and follow all isolation recommendations above if tested positive. Knowing one is infected early during quarantine enables (a) earlier access to treatment options, if indicated (especially for those that may be at risk for severe illness), and (b) notification of exposed persons (close contacts) who may also benefit by knowing if they are infected. If testing negative before Day 3, retest at least a day later, during the 3-5 day window following exposure.


Severe Symptoms:

If you experience severe symptoms, such as shortness of breath or if your symptoms do not improve, contact your medical provider or report to the nearest Emergency Room.


Guidance for Businesses:

In workplaces, employers are subject to the Cal/OSHA COVID-19 Emergency Temporary Standards (ETS) or in some workplaces the Cal/OSHA Aerosol Transmissible Diseases (ATD) Standard and should consult those regulations for additional applicable requirements. No person can be prevented from wearing a mask as a condition of participation in an activity or entry into a business.


Isolation & Quarantine – Definitions:

Quarantine: Restricts the movement of persons who were exposed to a contagious disease in case they become infected.

Close Contact: Someone sharing the same indoor airspace, e.g., home, clinic waiting room, airplane etc., for a cumulative total of 15 minutes or more over a 24-hour period (for example, three individual 5-minute exposures for a total of 15 minutes) during an infected person's (laboratory-confirmed or a clinical diagnosis) infectious period.

High-Risk Contact: Someone who may experience severe illness if they become infected with COVID-19 or for whom the transmission potential is high (high intensity/duration of indoor exposure). Examples of high-risk contacts include immunocompromised persons and household contacts of cases.

Infectious Period: For symptomatic infected persons, 2 days before the infected person had any symptoms through Day 10 after symptoms first appeared (or through Day 5 if testing negative on Day 5 or later), and 24 hours have passed with no fever, without the use of fever-reducing medications, and symptoms have improved, OR

For asymptomatic infected persons, 2 days before the positive specimen collection date through Day 10 after positive specimen collection date (or through Day 5 if testing negative on Day 5 or later) after specimen collection date for their first positive COVID-19 test.

High-Risk Exposures: Certain unmasked activities with increased or prolonged close face-face contact.Or if the close contact is more likely to become infected due to being unvaccinated, immunocompromised, or if they are more likely to transmit the virus to those who are at higher risk for severe COVID-19.

High-Risk Settings: One in which transmission risk is high (e.g., setting with many persons who may not receive the full protection from vaccination due to co-existing medical conditions), and populations served are at risk of more serious COVID-19 disease consequences including hospitalization, severe illness, and death.

*CDPH recommends the following work exclusions for staff working in these settings to protect the populations served, and maintaining quarantine recommendations for patients, residents and clients served in these settings, consistent with CDC recommendations.


Post-Infection Therapies and Medications:

Monoclonal Antibody Therapy and Oral Antiviral Medications have received emergency use authorization (EUA) for the treatment of COVID-19 symptoms. However, supplies are limited; prescriptions for therapies/medications will be available on a first-come, first-served basis for those who meet medical criteria.
