Anyone who is in close contact or thinks they have been exposed to someone who tests positive for COVID-19 should get tested as soon as possible.


For those who will be sharing the same household and are able to quarantine at home, the Public Health staff will give advice on how to stay safe and how long to stay home. 


Once someone is recovered, if the rest of the household contacts are negative, it is safe for the person to return home and/or resume normal household activities.

If you test positive for COVID-19 and have symptoms, you may discontinue isolation if the following conditions are met:

  • at least 3 days (72 hrs.) have passed without fever (without the use of fever-reducing meds) AND
  • improvement in respiratory symptoms (like cough, shortness of breath) AND
  • at least 10 days have passed since the symptoms first appeared (CDC updated this guidance to 10 days to reflect a longer duration of viral shedding.)

If you have no symptoms but are COVID-19 positive, you may discontinue isolation once 10 days have passed since the date of your first positive test, if you remain symptom-free. Afterward, you should continue to stay 6 feet away from others and wear a face mask as directed by the current Public Health Order.

Please read Marin County’s At Home Quarantine & Isolation Safety guidance document (published 4/5/20) for important information and practical tips.

We recommend leaving your children at home in the care of another adult. If you have no other option, you are welcome to bring your child.

Even people without symptoms can have COVID-19 and give it to others. It’s important to get tested to help protect the people who you live, work, and interact with so they don’t get the virus. For adults over 65 and people with certain health conditions, being exposed to COVID-19 could be deadly. Testing is one of the best ways to protect our community and our loved ones from getting sick or dying from COVID-19.

Marin Public Health's team of "contact investigators" play a crucial role in the COVID-19 response. This practice is commonly referred to as contact tracing.

When a person tests positive for COVID-19, the team calls the person to gather a list of close contacts who are at high risk of exposure. Everyone on that list is then contacted to arrange for testing and quarantine in order to stop the spread of COVID-19.  While these close contacts are awaiting test results, they are commonly referred to as a Person Under Investigation (PUI).

In addition to gathering a list of close contacts, the contact investigation team evaluates symptoms and provides education regarding quarantine and/or isolation for COVID-19 infected persons, PUIs and any members of their households.

Here is some additional information from Marin's Public Health Officer about how contact tracing works and why it is important.

Last Updated 05/23/2020 - 13:31

When a COVID-19 case is confirmed, our Public Health team conducts a contact investigation (also known as contact tracing), which focuses on identifying, testing and isolating people with high or medium risk of infection from a confirmed case. The contact investigation will review the places and people the confirmed cases may have come into contact with during the time the case would have been infectious. Any people or places believed to be high or medium risk will then be contacted to proceed with testing and isolation.

Below is a table from the CDC, clarifying the types of exposure that might lead to infection. Most importantly, the CDC clarifies brief encounters in the community do not carry significant risk.

Risk Level Exposures Identified Through Contact Investigation
No Identifiable Risk Interactions with a person who has symptomatic laboratory-confirmed COVID-19 that do not meet any of the high-, medium-, or low-risk conditions below, such as walking by the person or being briefly in the same room.
Low Risk Being in the same indoor environment (e.g., classroom, a hospital waiting room) as a person with symptomatic laboratory-confirmed case of COVID-19 for a prolonged period of time, but not meeting the definition of closed contact
Medium Risk
  • Close contact with a person laboratory-confirmed case of COVID-19
  • On an aircraft, being seated within 6 feet of a traveler with symptomatic laboratory-confirmed COVID-19 infection (approximately two seats in any direction)
  • Living in the same household as, and intimate partner of, or caring for a person in a non-healthcare setting (such as a home) to a person with symptomatic-laboratory confirmed COVID-19 infection while consistently using recommended precautions for home care and home isolation
High Risk Living in the same household as, being an intimate partner of, or providing care in a nonhealthcare setting (such as a home) for a person with symptomatic laboratory-confirmed COVID-19 infection without using recommended precautions for home care and home isolation

If believe you have experienced a high or medium risk exposure to someone with COVID-19, you should quarantine yourself in your home and contact your healthcare provider.  If you do not have a healthcare provider, call (415) 473-7191.

Yes. Your personal information will not be not shared.

Test results are only shared with the referring healthcare provider and Marin Public Health. 

Marin Public Health does not release any identifying information about individuals.  The only information publicly reported is age range, race and gender.  That information is shared on Marin's Coronavirus Data Page in compliance with the Health Insurance Portability and Accountability Act of 1996 (HIPAA).

A nurse from Marin County Public Health will contact you and give you instructions on how to protect yourself and your family or anyone else in your household.

If you test positive, even if you do not feel sick, you should immediately isolate yourself in a room of your home away from anyone else you live with. 

Follow your healthcare provider’s advice and take all hygiene and disinfectant precautions to prevent anyone else from getting sick.  See the Quarantine and Isolation guidance for details.

It currently takes 2-5 business days to get the results from a COVID-19 test.  Depending on your testing location, a Marin County Public Health Nurse or your doctor will call you with your test results. 

While you are waiting on your results, you must self-quarantine:

  • Do not leave your home:  Except for a medical emergency, you should not leave your home.  A household member or friend should handle any outside activities that are allowed under the shelter-in-place order, such as grocery shopping.
  • Quarantine yourself to a small space in your home: If possible, designate a room and bathroom that only you will use until you know your test results.  The smaller the area, the easier it will be to disinfect it properly.

For detailed guidance see Post-Test Isolation Guidance.

If you test positive, a Marin County Public Health representative will contact you to conduct a contact tracing investigation.  This investigation identifies any close contacts who are at high risk of exposure and will need to isolate from others and be tested for COVID-19.

Not everyone needs to be tested for COVID-19.

Here is some information that might help in making decisions about seeking care or testing.

  • Most people have mild illness and are able to recover at home.
  • There is no treatment specifically approved for this virus.
  • Testing results may be helpful to inform decision-making about who you come in contact with.

Decisions about testing are based on a variety of factors including risk factors for serious illness, age, occupation, local epidemiology, and where the person is in their illness.

Clinicians should work with Marin HHS to coordinate testing through public health laboratories, or work with clinical or commercial laboratories. All test results should be reported back to Marin HHS.

Marin County Public Health is reporting test results based on laboratory reporting to the state. On March 24, Bay Area public health officers issued an order that requires commercial labs to report all results (positive and negative). But we are still seeing lags in reporting, which makes it difficult for public health officials to provide an accurate testing picture for Marin.

You can view current test results on our data page.

Testing starts with your medical provider. Anyone experiencing symptoms consistent with COVID-19 should immediately call their medical provider and seek testing.

Your medical provider will want to test for possible conditions such as flu, strep, or pneumonia. If your doctor believes you are a candidate for testing, they will refer you to either Marin Public Health or a suitable test center to conduct the testing.

Marin County Public Health also recommends testing for some groups, even if they do not have symptoms, including:

  • All persons who were notified that they were exposed to someone who was confirmed to have COVID-19; and
  • All persons who were notified by Marin Public Health as being high risk based on outbreak investigations; and
  • All essential public and private sector workers (cities and town workers included); and
  • Certain occupations with higher risk of exposures, including some healthcare workers and first responders. Testing for these individuals is arranged through their employer.

Our current data indicate that the virus is widespread in the county and, therefore, everyone in the county has a risk of exposure to the virus regardless of where in the county they live. Every hospital in the county is caring for patients who have COVID-19. Providing information on individual cases, therefore, does not provide any benefit to the public, and may instead mislead those not living in a neighborhood with many confirmed cases to falsely think that they are at lower risk.
