Revised Public Health Emergency Isolation Order for COVID-19

DATE OF ORDER: January 5, 2022

Please read this Order carefully.  Violation of or failure to comply with this Order is a misdemeanor punishable by fine, imprisonment, or both.  (California Health and Safety Code § 120275, et seq.)


  1. This Order supersedes the December 21, 2021 Order of the County of Sonoma Health Officer C19-31-I and shall become effective beginning at 12:01 a.m. on January 6, 2022, until rescinded, superseded, or amended in writing by the Health Officer.
  2. California is in a State of Emergency because of the coronavirus pandemic. The spread of the Novel Coronavirus (COVID-19) is a substantial danger to the health of the public within the County of Sonoma (“County”). COVID-19 can easily spread between people who are in close contact with one another. This Order is based on scientific evidence and best practices as currently known from the Centers for Disease Control and Prevention, the State of California, and the Sonoma County Health Officer to protect vulnerable members of the public from avoidable risk of serious illness or death resulting from exposure to COVID-19.
  3. The age, condition, and health of a significant portion of the population of the County places it at risk for serious health complications, including death, from COVID-19.  There is evidence of transmission risk from infected persons before the onset of symptoms.  Thus, all individuals who contract COVID-19, regardless of their level of symptoms (none, mild, or severe), may place other members of the community at risk for infection, illness and significant morbidity.
  4. To help slow COVID-19’s spread, protect all members of the community, especially the most vulnerable individuals, and prevent the healthcare system in the County from being overwhelmed, it is necessary for the Health Officer to isolate persons with COVID-19 and persons likely to have COVID-19 as determined by their treating provider.
  1. Any person who has COVID-19, as defined in Paragraph 6, and any person who likely has COVID-19, as defined in Paragraph 7, must isolate themselves and follow all instructions in this Order.  Isolation is required because a person with COVID-19 can easily spread the virus to others.  Isolation separates these persons from others to prevent the spread of COVID-19.
  2. For purposes of this Order, a “person who has COVID-19” is a person who is diagnosed with COVID-19 based on a positive test for the presence of the coronavirus (known as SARS-CoV-2) that causes COVID-19.
  3. For purposes purposes of this Order, a “person who likely has COVID-19” is a person who is displaying or reporting symptoms of COVID-19 and a health care provider, in consultation with the Sonoma County Department of Health Services, Disease Control Unit, determines based on those symptoms and any other risk factors that the person is likely to have COVID-19.
  4. Any person who has COVID-19, and any person who likely has COVID-19, must immediately take the following actions:
    1. Isolate themselves in their home, another residence, or a location offered by the County. They may not leave their place of isolation or enter any other public or private place except to receive necessary medical care or during an emergency that requires evacuation to protect the health and safety of the person.
    2. Review and follow all requirements listed in Self-Isolation Instructions for Individuals with COVID-19, which can be located here: https://www.cdph.ca.gov/Programs/CID/DCDC/Pages/COVID-19/Guidance-on-Isolation-and-Quarantine-for-COVID-19-Contact-Tracing.aspx. This order shall also apply to any future amendments to the state guidance.
    3. Refer their close contacts to the Self-Quarantine Instructions for Individuals Exposed to COVID-19, which can located here: https://www.cdph.ca.gov/Programs/CID/DCDC/CDPH%20Document%20Library/COVID-19/selfq_handout.pdf. Close contacts have likely been exposed to COVID-19 and if infected, can easily spread COVID-19 to others, even if they have only mild or no symptoms.  These may include persons who:
      • live in, have visited, or have stayed overnight at the individual’s residence; or
      • are intimate sexual partners of the individual; or
      • worked within six feet of the individual; or
      • attended a gathering or event in which social distancing of six feet could not be maintained, fully vaccinated and unvaccinated individuals attended the gathering and adherence to masking was not strictly adhered to;
      • provide care to the individual without wearing a mask, a face shield or goggles, gown and gloves; or
      • have been identified as close contacts by the Sonoma County Department of Health Services.
  5. Healthcare personnel shall comply with the California Department of Public Health (CDPH) Guidance on Quarantine for Health Care Personnel (HCP) Exposed to SARS-CoV-2 and Return to Work for HCP with COVID-19, which can be located here: https://www.cdph.ca.gov/Programs/CHCQ/LCP/Pages/AFL-21-08.aspx.
  6. The Sonoma County Health Officer may take additional action(s), which may include civil detention or requiring an individual to stay at a health facility or other location, to protect the public’s health if an individual who is subject to this Order violates or fails to comply with this Order.  Violation of this Order is a misdemeanor punishable by imprisonment, fine or both.
  7. Pursuant to Government Code sections 26602 and 41061 and Health and Safety Code section 101029, the Health Officer requests that the Sheriff and all chiefs of police in the County ensure compliance and enforce this Order.  The violation of any provision of this Order constitutes an imminent threat to public health.
  8. Copies of the Order shall promptly be made available (1) at the County Administration Center at 575   Administration Drive (2) by posting on the County’s website and (3) provided to any member of the public requesting a copy.
