Press Release 6-15-2020 - Sourced from:

Sonoma County public health officials are asking everyone in Sonoma County to get tested for COVID-19, including individuals without symptoms, and since the protests, definitely all those who were in large gatherings.   Health professionals say upwards of 40% of people who test positive experience no symptoms but are still spreading the disease. Community-wide testing allows health experts to assess how widespread and contagious the virus is in our communities and is a critical step toward re-opening the county.


With this information health workers can do timely  contact tracing  of individuals that may have been exposed to the virus and take targeted measures to help prevent the spread of the virus. The County offers free COVID-19 testing for all community members at multiple locations, including in Santa Rosa.


General Testing Information

There are two kinds of tests for COVID-19: viral tests and antibody tests.

  • A viral test tells you if you have a current infection. This test is now widely available.
  • An antibody test tells you if you had a previous infection. Find more information about local antibody testing sites.

Testing and Tracing is a critical step toward re-opening the County

Community-wide testing is a critical step toward re-opening the County and allows us to identify and increase our understanding of COVID-19 community transmission. This includes collecting a broad sample of results from people with or without symptoms. We know that upwards of   40% of people who test positive experience no symptoms (asymptomatic), but are still spreading the disease.

Those who are tested will be assessed for the need to quarantine.  Only those individuals with a temperature and flu-like symptoms will be required to quarantine while they await test results. Most will be free to continue their regular shelter in place while they await their test results.

For Those Who Can’t Be at Home, A Free, Safe Place to Quarantine or Isolate Offered by the County of Sonoma.

The County of Sonoma is offering temporary residence at the Sonoma State University Dormitories for people who need to self-isolate or quarantine, and do not have a way to do that safely at home.

People who test positive for COVID-19 are instructed to self-isolate to protect others from catching the virus. People who are awaiting test results and who have flu-like symptoms are also required to quarantine. People without these symptoms who get tested are not required to quarantine while they await test results.

Definition: Isolation and quarantine help protect the public by preventing exposure to people who have or may have a contagious disease.

  • Isolation separates sick people with a contagious disease from people who are not sick.
  • Quarantine separates and restricts the movement of people who were exposed to a contagious disease to see if they become sick.


These accommodations are free and available to anyone who cannot safely isolate at home. Multiple members of a family group that need to isolate are allowed, and can be together.

  • Individuals are welcome regardless of immigration status
  • Information collected is only for health purposes
  • Individuals who meet certain requirements of being vulnerable to COVID-19, even without a known exposure, qualify to use the dorms.

Case Investigation and Contact Tracing

The Department of Health Services (DHS) has expanded its system for monitoring cases and contacts by training more health investigators. This process helps break the chain of infection by monitoring people who have been exposed or infected as early as possible,  getting them to care, and helping them to isolate from others. Here are the steps incontact tracing:

Step 1:  Determine Contacts – DHS determines all the possible contacts of the person who tests positive, and attempts to get contact information for those people. The name and personal information of the person who tested positive for COVID-19 are never shared during the contact tracing process; revealing the name of the person is a violation of privacy laws.

Step 2:   Make Contact – DHS attempts to locate and contact all individuals with direct exposure, which is defined as prolonged contact of 15 minutes or more within 6 feet distance of each other, usually indoors. Based on an assessment of the contact, those contacts may be asked to  quarantine  for 14 days. Quarantine requires one to maintain physical distance from other people, and check symptoms daily.  If a contact receives a viral test and it is positive, they will be instructed to self-isolate. For someone that lives with others, this means staying in a specific “sick room” or area that is away from other people or animals, including pets. Use of a separate bathroom, if available, is best. Release from isolation is determined by Disease Control staff, following CDC guidance. In order to be released from isolation, at least 3 days (72 hours) must have passed since recovery (resolution of fever without the use of fever-reducing medication and improvement of respiratory symptoms and at least 10 days have passed since symptoms first appeared).

Step 3:  Assess Contacts:

  • Close contacts are asked to voluntarily comply with a daily assessment of their symptoms via phone call from a public health nurse for the 14 days of their quarantine.
  • Asymptomatic contacts are instructed to get tested approximately 7 days after the exposure.
  • All contacts with symptoms are tested as soon as possible

Testing, followed with quarantine of those who tested positive and tracing of those with whom the SARS-CoV-2 positive people had had contact, resulted in positive outcomes in reducing and sometimes preventing new infections.

Researchers working in the Italian town of Vò, the site of the first COVID‑19 death in Italy, conducted two rounds of testing on the entire population of about 3,400 people, about ten days apart. About half the people testing positive had no symptoms, and all discovered cases were quarantined. With travel to the commune restricted, this eliminated new infections completely. Source:

All quarantined individuals can be provided a letter to share with their employer (if needed).

Testing Results

  • If you test positive for COVID-19 by a viral test, know what protective steps to take if you are sick or caring for someone.
  • If you test negative for COVID-19 by a viral test, you probably were not infected at the time your sample was collected. However, that does not mean you will not get sick. The test result only means that you did not have COVID-19 at the time of testing.

If you test positive or negative for COVID-19, no matter the type of test, you still should take preventive measures to protect yourself and others.

Antibody Testing

An antibody test looks for antibodies, which show if you’ve had a previous viral infection. The antibody test isn’t checking for the virus itself. Instead, it looks to see whether your immune system — your body’s defense against illness — has responded to the infection. Depending on when someone was infected and the timing of the test, the test may not find antibodies in someone with a current COVID-19 infection. The test is a blood test performed through a blood draw.

An antibody test may not be able to show if you have a current infection, because it can take 1-3 weeks after infection to make antibodies. Therefore, antibody tests should not be used to diagnose someone to determine if they are currently sick with COVID-19. To see if you have a current infection, you need a viral test, which checks respiratory samples, such as a swab from inside your nose.

[While antibodies consist of proteins that typically help fight off infections, we do not know yet if having antibodies to the coronavirus can protect someone from getting infected with the virus again, or how long that protection might last.]
