With COVID-19 Omicron variant cases rising rapidly throughout our region and making up a large portion of the current cases in Yolo County, we want to share the latest information to help us return to school safely.

The Importance of Testing - Washington Unified strongly encourages all WUSD students and staff to get tested before returning to campus this week. In January 2022, WUSD begins its partnership with a new COVID-19 testing provider, Covid Clinic, to provide ongoing testing opportunities for all students and staff districtwide.

Covid Clinic will provide a similar level of services that WUSD families are currently experiencing with salvia-based PCR testing, and they can maintain WUSD’s current testing levels for all students, community, and staff to benefit from. For more information about WUSD-sponsored COVID-19 testing, visit

Vaccinations - The CDC urges every eligible person to get the COVID-19 vaccine and booster. Vaccination options are listed on the Yolo County website and are now widely available for children ages 5-11. For all vaccination locations including pharmacies and community clinics, visit or call (833) 422-4255. Contact your healthcare provider about the vaccine, boosters, and COVID symptoms. 

What WUSD is Doing to Maintain Safety - The rise in COVID-19 cases caused by the Omicron Variant is an important reminder that we need to continue to work together to do all we can to keep our schools safe. To this end, we want to assure you that we are taking every possible precaution available to ensure that our students and staff are safe and well-informed. WUSD remains committed to the entire community’s health, safety, and well-being. Our schools and offices will continue to follow all health and safety guidelines currently in place diligently. As a reminder, 
  • Indoor & outdoor masking is required at all WUSD sites. Please take a moment to ensure your child’s masks are in good condition and fit properly. Masks should fit snugly on your child’s face, completely cover their nose and mouth, and be washed regularly.
  • Weekly COVID-19 testing is strongly recommended,
  • Stay home when experiencing any symptoms of a cold or flu,
  • Follow ongoing hand washing and sanitizing processes,
  • Get vaccinated and boosted as soon as possible,
  • The District’s HVAC systems continue to operate with high-grade MERV 13 filters along with portable HEPA air purifiers in every classroom and office space,
  • All high touch surfaces (desktops and sides, sink fixtures, counters, dispensers, tables, cafeteria tables, and staff lounge tables, doors, doorknobs and door jams) are cleaned and disinfected daily,
  • Students and staff should self-monitor their health at home before arriving at school or work.


On January 4, 2022, following recommendations from the Centers for Disease Control and Prevention (CDC) and the California Department of Public Health (CDPH), Yolo County has revised its local health orders to align with shortened COVID-19 isolation (PDF) and quarantine (PDF) periods, reducing the duration of isolation and quarantine to 5 days instead of the earlier 10 for most individuals. The shortened isolation and quarantine periods are based on scientific studies that show most transmission of the virus that causes COVID-19 occurs early in the course of illness, generally in the 1-2 days before the onset of symptoms and the 2-3 days after.
Isolation for individuals who have tested positive for COVID-19 can now end after 5 days, but only if the person has no symptoms or symptoms are improving, tests negative on day 5 or later, and wears a mask that fits and filters well over their mouth and nose when around others indoors until day 10. Because PCR tests can result in a positive test for a month or longer after infection, tests to end isolation need to be antigen tests. Yolo County has started planning to make free home antigen tests available to those testing positive.
Quarantine for individuals who have been exposed to someone with COVID-19 can now end after five days with a negative test on day 5 or later if the individual wears a mask that fits and filters well over their mouth and nose when around others indoors until day 10. The test to end quarantine can be either an antigen test or a PCR test. Individuals who have tested positive in the previous 90 days are no longer exempt from quarantine after close contact with someone with COVID-19, nor are individuals who are eligible for a booster dose but have not yet received their booster.
As part of the new guidance, home antigen test results will now be accepted as proof of either a negative or positive test, although some workplaces or schools can and may have stricter requirements. At a minimum, an individual should document their home test result with a photo of the test result, the individual’s name, and the date and time of collection. Individuals testing positive with a home test should report their test results to their healthcare provider or call Yolo County Public Health at 1-833-YOLOCOV (965-6268). An online reporting platform is under development as home tests become more common.
Isolation and quarantine periods for health care workers are different from those of the general public. Depending on vaccination status and whether critical staffing shortages are occurring, health care worker isolation and quarantine range from 0 to 10 days.
