UC Davis COVID-19 Dashboard

UC Davis is monitoring COVID-19 in our campus community, with data from campus wastewater testing, saliva testing, variant genotyping, self-reported cases and vaccination rates.

Interactive data below start with monitoring on-campus cases — including campus wastewater monitoring and all known on-campus cases. You can click through the tabs at the top to view data from on-campus saliva testing and genotype tracking of COVID-19 variants. UC Davis vaccination rates provide baseline information about our community.

All students and employees are required to report a COVID-19 diagnosis and to comply with vaccine policy. Our COVID-19 saliva testing is an option available to all employees and students on the Davis and Sacramento campuses.

Understanding current campus health and virus metrics helps us all make better decisions.

UPDATE: After Sept. 24, vaccination compliance rates reflect the addition of the bivalent booster to CDC recommendations and to the UC Vaccine Policy. See our COVID-19 vaccine policy webpage for more details.


Data Sources and Definitions

Data above are updated at least once per week. Information is provided by Student Health and Counseling Services, Occupational Health, UC Davis Health, the Genome Center and Associate Professor Heather Bischel's lab (Department of Civil and Environmental Engineering).

Monitoring COVID-19 On Campus

  1. Normalized SARS-CoV-2 concentration: Or N/PMMoV. Presented as a 7-day moving average, this normalized concentration measures the amount of the SARS-CoV-2 N gene, which is present in nearly all variants of the virus. In this graph, the concentration of the N gene is normalized in comparison to the concentration of pepper mild mottle virus, or PMMoV, which serves as an indicator of “fecal strength” of each sample as one of the most abundant viruses found in human waste. This helps to normalize samples based on population size, rain or water usage. More data available on the Healthy Central Valley Together website.
  2. Asymptomatic Testing Positive Results: We are reporting the number of students and employees diagnosed with COVID-19 last week through campus saliva testing. Learn more about UC Davis COVID-19 testing.
  3. SHWC Testing: This category includes any other COVID-19 testing conducted on campus, operated by the UC Davis Student Health and Wellness Center (SHWC). This includes testing for students who have symptoms concerning for COVID-19 or those who have had close contact with diagnosed individuals — who are being cared for by Student Health and Counseling Services as their medical provider. It also includes tests ordered by Occupational Health for select employee groups.
  4. Self-Reported On-Campus: All students and employees have been required to self-report by email if they or someone they live with are diagnosed with COVID-19 or suspect they have COVID-19. Displayed here are only those self-reported cases wherein the individual was on campus during the 14 days prior to their positive test.
  5. Totals since 9/2020: A cumulative view since the asymptomatic testing program first began on Sept. 14, 2020, with students moving into campus residence halls. Since that time, testing eligibility has expanded to all students and employees. Testing is currently optional. Learn more about UC Davis COVID-19 testing on campus.

COVID-19 Testing On Campus

  1. Asymptomatic Tests: We are reporting the number of tests performed last week for symptom-free students and employees. Learn more about UC Davis COVID-19 testing.
  2. Positive Results: The number of students and employees diagnosed with COVID-19 last week through the asymptomatic testing kiosk.
  3. Positivity Rate: A rolling average calculated from the percentage of positive results to total tests from the asymptomatic testing kiosk during the last seven days. Positivity rates that display for future dates are incomplete, as they do not yet include seven days’ worth of data.
  4. Totals since 9/2020: A cumulative view since the asymptomatic testing program first began on Sept. 14, 2020, with students moving into campus residence halls. Since that time, testing eligibility has expanded to all students and employees. Testing is currently optional. Learn more about UC Davis COVID-19 testing on campus.

Tracking COVID-19 Variants

  1. Genotyped samples: Saliva samples found positive for COVID-19 that also resulted in usable genotype results. While all positive samples from saliva testing of students and employees (through testing on campus and Healthy Davis Together, when applicable) are genotyped to track variants, not all positive samples return informative results.
  2. Variant type: Positive test results from UC Davis saliva testing are genotyped for variants defined by CDPH and CDC as variants being monitored, variants of concern and variants of interest. Genotyping is tailored to the variants prevalent at any given time. As of the most recent dashboard update, the assays run at the UC Davis Genome Center can detect Omicron (sublineages BA.1, BA.2, BA.2.12, BA.2.75, BA.3, BA.4, BA.4.6, BA.5 and BQ.1). Any sample that is not one of these variants will be sequenced for variant determination. Variants genotyped previously were Alpha, Beta, Gamma, Epsilon, Iota, Kappa, Mu and Delta. Definitions of variants and sublineages are highly dynamic and data may be updated retroactively to reflect current public health knowledge and priorities. Data related to variants before March 2022 can be found on the Healthy Davis Together website.
  3. Omicron: Samples shown as “Omicron” (Pango lineage B.1.1.529) are samples whose sublineage (e.g., BA.1, BA.2, BA.4 or BA.5) could not be determined.

UC Davis Vaccination Rates

  1. UC Davis Students: Vaccination and compliance rates as currently reported to Health-e-Messaging among undergraduate and graduate students attending UC Davis in the current quarter (or most recent quarter of the academic year), including students in the School of Medicine and Betty Irene Moore School of Nursing. Exact enrollment totals are fluid and reflected in percentage calculations.
  2. Davis Campus - Employees: Vaccination and compliance rates as currently reported to Health-e-Messaging among UC Davis employees, including those working from home or at satellite locations, but not including UC Davis Health employees. Only current, non-student employees who receive paychecks are included among the "current on vaccine" calculation.
  3. UC Davis Health – Employees: Vaccination and compliance rates of employees of the UC Davis School of Medicine, UC Davis Betty Irene Moore School of Nursing, UC Davis Medical Center and UC Davis Medical Group, as reported by UC Davis Health.
  4. Policy Compliant: Percentage who are currently compliant with UC Vaccine Policy by either verifying that they are current on vaccine status (fully vaccinated and "up to date" on any recommended boosters) or by securing an approved exception. As compliance rates approach 100%, this display will be capped at 99%, as we expect new employees and students will continue to go through the process of becoming compliant in the future.
  5. Current on Vaccine: Percentage who have verified that they have completed a COVID-19 vaccination series and are "up to date" on any recommended boosters that they are eligible for, per CDC guidance.
  6. Approved Exceptions: Percentage who have secured an approved exception, according to UC Vaccine Policy.
  7. In Progress: Percentage who are either not compliant with UC Vaccine Policy or who have initiated the process to become fully compliant with UC Vaccine Policy, but are either awaiting the completion of their vaccination series and two-week waiting period or are awaiting final decisions regarding their request for an exception. Low rates are rounded up to 1%.

 

  • UPDATED: Does this updated dashboard reflect all of the COVID-19 testing on campus?
  • Yes. We have updated the dashboard in September 2022 to reflect campus wastewater testing and variant monitoring — in addition to campus COVID-19 testing, which is now optional. In December 2020 we updated the dashboard to include not only the asymptomatic testing from the UC Davis testing program, but also test results from the UC Davis Student Health and Wellness Center, which includes testing for students and employees who are symptomatic, have been identified as close contacts and other situations (labeled as "SHWC testing" in the graphics above). (Updated Sept. 16, 2022)
  • Where is COVID-19 data for the city of Davis?
  • The Yolo County data on the California Department of Public Health COVID-19 Dashboard provides data about new coronavirus cases, deaths, testing, positivity and vaccination rates in Yolo County. UC Davis reports positive results from both the asymptomatic kiosk testing and from the Student Health and Wellness Center (as a medical provider) to the State of California, so that Yolo County can include campus data in its dashboard. Test results for students and employees who have been tested by other medical providers are otherwise included in COVID-19 data for their county of residence. (Updated July 14, 2022)
  • UPDATED: How do I find out about COVID-19 variants in Davis?
  • We updated this dashboard to reflect COVID-19 variants from campus testing, back to March 2022. Historic data on COVID-19 variants are available on the Health Davis Together website, which combines results from testing on campus, in the Davis community and elsewhere in Yolo county. The team at the UC Davis Genome Center genotypes all positive samples to identify known variants of the SARS-CoV-2 virus, and later sequences many of them as well to confirm results and reveal the presence of any novel changes to the viral genome. (Updated Sept. 16, 2022)
  • If I live or work in Davis, how do I get tested for COVID-19?
  • If you are currently a registered UC Davis student, and you do not have symptoms, then you are eligible to get tested for COVID-19 at the campus kiosk. See UC Davis COVID-19 Testing for more information about this free testing and about testing requirements as a student. If you do have symptoms, then please contact Student Health or your medical provider.

    If you are a UC Davis employee who receives paychecks through UCPath, and you do not have symptoms, then you are eligible to get tested for COVID-19 at through a UC Davis testing kiosk. See UC Davis COVID-19 Testing for more information about this free testing, testing locations and about testing requirements as an employee. If you do have symptoms, then please contact your medical provider or Occupational Health.
