DATE OF ORDER: December 23, 2021

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


  1. Summary. This Order of the Health Officer requires public and private schools serving students in Transitional Kindergarten through grade 12 to require Workers to get tested twice weekly for the virus that causes Coronavirus Disease 2019 (“COVID-19”) or produce satisfactory evidence that they are Fully Updated against COVID-19.
  2. Effective Date and Time. This Order takes effect at 12:01 a.m. on February 1, 2022.
  3. Basis for Order. On August 11, 2021, the California Department of Public Health (“CDPH”) issued an order requiring all public and private schools serving students in transitional kindergarten through grade 12 to verify the COVID-19 vaccination status of all workers and to require unvaccinated or incompletely vaccinated workers to undergo diagnostic screening testing.This Order is made in light of the emergence in Sonoma County of the Omicron variant of SARS-CoV-2, the virus that causes COVID-19, and the imminent threat that it poses to the health of vulnerable residents and the capacity of the healthcare system.  Emerging evidence indicates that the Omicron variant is significantly more transmissible than prior variants of the virus, and that individuals who have had only their initial vaccine series and are eligible for the booster, are susceptible to the Omicron variant.However, initial evidence also shows that individuals who have received a booster shot increase their immunity to a level that confers more protection from all circulating SARS-CoV-2 variants, including the Omicron variant.  The CDC and the CDPH now recommend that all eligible persons receive a booster shot because immunity wanes several months after completion of the initial vaccine series.Vaccination is a safe and effective critical component in preventing COVID-19 and its associated harms.  Individuals who have not received a booster shot are more likely to become infected and spread infection to others, and more likely to become seriously ill or die. Workers in schools should receive booster shots when eligible to maintain the protective effect of the high community-wide vaccination rates in our County.After consulting with local school and community leaders, I have determined that it is necessary and appropriate to require all schools subject to the CDPH order to require Workers to get tested twice weekly for the virus that causes Coronavirus Disease 2019 (“COVID-19”) or produce satisfactory evidence that they are Fully Updated against COVID-19.  This order is necessary to ensure that we collectively protect the health and well-being of all; keep schools open for in-person instruction; and allow Sonoma’s economy to remain open and thrive.
  4. COVID-19 Test Requirements. Except as set forth in Section 4 of this Order, an Employer shall require all of its Workers to do the following:
    1. Receive a COVID-19 Test at least twice a week; and
    2. Unless test results are sent directly to the Employer by the test provider, Workers must promptly provide the results of each COVID-19 test to the Employer for Record-Keeping.

    Employer may confirm a positive antigen test with a confirmatory nucleic acid amplification test; Employer shall not use another antigen test to confirm a positive antigen test.  Employer must exclude from work any Worker who receives a positive antigen test.

  5. Fully Updated Workers. An Employer may exempt the following Workers from being subject to the COVID-19 Test Requirements set forth in Section 3 of this Order:
    1. Fully Updated Workers; and,
    2. Fully Vaccinated Workers who are not eligible for a booster (as defined below in Fully Updated). Fully Vaccinated Workers must show proof to their Employer that they have received a booster dose of a COVID-19 vaccination within fifteen (15) days of becoming eligible, or they must be subject to the COVID-19 Test Requirements (Section 3 above).

    An Employer may accept any of the documentation allowed in CDPH Order for Vaccine Verification for Workers in Schools.  In the absence of knowledge to the contrary, an Employer may accept the documentation presented as valid.

Workers who are subject to the COVID-19 Test Requirements (Section 3 above) must wear FDA-cleared surgical masks or respirators in indoor work settings, unless exempted from wearing a face covering under Cal/OSHA COVID-19 Emergency Temporary Standards and/or the Cal/OSHA Aerosol Transmissible Diseases Standards.
  7. Record-Keeping Requirements. An Employer must keep and maintain a record of the following information for the purpose of inspection by an authorized representative of the Health Officer:
