Contact Tracing

UC Davis collaborates with local public health officials for contact tracing, to help prevent the spread of the coronavirus.

Act as if COVID-19 is around you. Stay current on testing and cover your face.

How contact tracing works at UC Davis

On the Davis campus, positive test results for COVID-19 are reported to Yolo County Public Health and delivered securely to a case investigator at Student Health and Counseling Services.

1. The case investigator reaches out to an individual who has tested positive for COVID-19 on campus to:

  • alert them to their positive diagnosis
  • provide direction and support for quarantine/isolation
  • provide consultation and appointments for medical care
  • gather information about recent close contacts and social activities
  • For those diagnosed with COVID-19 outside of campus testing
  • Employees and students who are diagnosed with COVID-19 outside of campus testing are also required to report their diagnosis to UC Davis, in part so that the campus contact tracing team can follow up regarding potential close contacts and facility exposure risks within the Davis campus community. Employees and students are required to cooperate with the contact tracing process in a timely fashion.


2. UC Davis contact tracers will then ONLY reach out to on-campus individuals identified as "close contacts" to provide guidance on quarantine, testing and care per public health guidance.

  • When it comes to off-campus activities and close contacts, the team will work closely with public health authorities for contact tracing beyond campus.
     

3. Campus contact tracers also notify Safety Services of any campus facilities used by a diagnosed individual, for cleaning protocol and potential worksite notification of other on-campus close contacts if needed.

  • The CDC describes cleaning and disinfection procedures for areas used by someone diagnosed with COVID-19, and defines the timeline after which the area no longer requires additional cleaning.

Get Notified if You're a Close Contact

ca notify logo

CA Notify allows you to find out if you were exposed to COVID-19 (e.g., classmate on campus). You can also notify close contacts if you test positive, while remaining anonymous. 

Close Contacts

A "close contact" is someone who was within 6 feet of a person infected with COVID-19 for at least 15 minutes, over a 24-hour period. An infected person can spread COVID-19 starting from 48 hours (or 2 days) before the person has any symptoms or tests positive for COVID-19.

UC Davis contact tracers will ONLY reach out to on-campus individuals identified as "close contacts" and will provide guidance on quarantine, testing and care per public health guidance.

Fully vaccinated close contacts
Fully vaccinated people, who have come into close contact with someone with COVID-19, and have no symptoms, are not required to quarantine. The CDC does recommend testing 3-5 days after the exposure.

Testing for close contacts
Employees and students identified as a close contact cannot access ARC testing facility. Close contacts can get tested at Healthy Davis Together’s Cannery Location, primary care provider, or Student Health and Counseling Services (students only) 

The confidentiality of individuals with positive results will be protected, and their name and COVID-19 status will not be shared with close contacts.


Close Contact Scenarios

These are the most common scenarios reported by the UC Davis Contact Tracing Team and explain when people get notified and required to isolate/quarantine, while others can continue accessing campus.

Hi I'm Sam and I've got COVID-19. My Daily Symptom Survey badge color is RED
  •  Scenario 1: No close contacts
  • illustration of one person - purple - who has covid.
    Sam (purple) was in Olson Hall but never spent 15 minutes near anyone.
     
    Without Close Contacts, there is nothing for the Contact Tracing Team to investigate.

    The Contact Tracing Team will assist Sam and issue a Worksite Exposure Report notice that
    Olson Hall was exposed to COVID-19, which goes out to everyone who completed the Daily Symptom Survey that day. 

     

  •  Scenario 2: Multiple close contacts
  • illustration of three people at the office with the colors green, purple and red.
    Sam (purple) was in a conference room in Tupper Hall in Close Contact with two people
     
    Green is a Close Contact, is vaccinated and has no symptoms.

    Daily Symptom Survey badge color is Green

    Contact tracers will recommend that Green test in 3-5 days. Green can continue accessing campus facilities.  

    Red is a Close Contact and is vaccinated, but has symptoms.

    Daily Symptom Survey badge color is Red

    Contact tracers will direct Red to quarantine and to test immediately. Red cannot access campus facilities.

     

  •  Scenario 3: COVID, Close Contacts and Quarantine at Home
  • illustration of four people at home with the colors green, blue, purple and red.
    Contact Tracers will find out whether Sam (purple) has Close Contacts at home.
     
    Green lives with Sam, but is NOT a Close Contact

    Whether vaccinated or not, Green may continue accessing campus facilities, but should test and monitor for symptoms.

    Daily Symptom Survey badge color is Green.

    Blue lives with Sam, is vaccinated, and is identified as a Close Contact

    As long as Blue remains asymptomatic they can continue to access university facilities as usual.

    Daily Symptom Survey badge color is Green.

    Red lives with Sam, is unvaccinated, and is identified as a Close Contact

    Red will need to follow quarantine rules as directed by a contact tracer and cannot access campus facilities.

    Daily Symptom Survey badge color is Red. 

     


UC Davis ONLY notifies:

  • Employees and students defined as a close contact of someone diagnosed with COVID-19
  • Supervisors of employees directed to isolate/quarantine
    Supervisors will be notified about work restrictions and the employee's need to collect a doctor’s note prior to returning to work.
    • Supervisors should not send any further communication regarding the work restriction to anyone else.
    • Supervisors may communicate needed adjustments to workload and schedule if the work restriction affects business process needs.
       
  • When there is a potential worksite exposure
    UC Davis reports potential worksite exposures to COVID-19, pursuant to AB 685. Anyone who has completed the Daily Symptom Survey in the last 14 days receives a daily email with reports about worksites where someone infected with COVID-19 was present. 
    • If you were in a worksite where a potential exposure occurred, it doesn’t necessarily mean you were exposed. 
    • If you require isolation/quarantine as a close contact, then a member of the UC Davis contact tracing team will contact you directly.
       
  • Facility managers when there is a CDC-defined need to clean or disinfect a facility because of a known exposure. 
    • Safety Services will provide facility managers guidance on communications and when a closure/disinfection is needed.
    • Facility managers will not send broad communications, which are covered by UC Davis' daily worksite exposure notification. 

You will NOT be notified…

  • When a student of yours is placed in isolation/quarantine
  • When a coworker is placed in isolation/quarantine
  • When a classmate is placed in isolation/quarantine
  • If contact tracers don't consider you exposed to COVID-19 or a close contact
  • Simply because you shared a classroom or workspace with someone diagnosed with COVID-19
Why wasn't I notified?
If you are not a close contact, a supervisor or otherwise potentially affected by a CDC-defined facility exposure, then this information can infringe on the privacy of the infected individual, and there is nothing actionable about having that information.
