Contact Tracing FAQs

Updated January 26, 2022

Why wasn’t I contacted by the Yale Contact Tracing team (YCTT)?
The Yale Contact Tracing team conducts contact tracing with individuals who test positive for COVID-19 (cases) at Yale. The Contact Tracing team relies on the case interview to gather important details about who they were in contact with, when and where. We have a team of tracers working 7 days a week with the goal of reaching all cases and contacts within 24 hours. Still, this process takes time.

You may NOT have been called because:

  1. Your contact with the case was outside the infectious window. We request information on contacts who were exposed to the case two days before they had symptoms, or two days before their test. If you were not in contact during that time, you would not be notified.
  2. You were not a close contact.  If your contact with the case was within the infectious period but was not within 6 feet for 15 minutes or more over a 24-hour period, you would not be notified as a close contact.
  3. YCTT protocols have been updated. We ask individuals who are infected with COVID-19 to inform household members/suitemates and those they were in contact with that they were potentially exposed. During the surge, we will prioritize contact tracing in areas with ongoing transmission and among our highest-risk groups. Close contacts can review the exposure guidance and quarantine requirements, determine which category is most appropriate based on their vaccination and booster status, and follow the applicable guidance to help decrease the risk of spreading COVID-19.

If you think you meet the criteria of a close contact, you can schedule a test, monitor your symptoms, and reach out to or call the Campus COVID Resource Line (CCRL) at 203-432-6604 for further guidance.

If I was vaccinated for COVID-19, do I still need to quarantine? What if I’m not vaccinated or boosted?
Once identified as a close contact, the guidance you follow is based on your vaccination status.

Monitoring means:

  • masking in indoor/outdoor settings,
  • monitoring symptoms daily, and,
  • self-isolating and scheduling a symptomatic test if symptoms develop.

Quarantine means:

  • staying at home, not going to work/school,
  • maintaining social distancing within household/suite as much as possible, and,
  • monitoring as described above.

If you are a healthcare worker and/or an employee at Yale Health, please follow the guidance for vaccinated and boosted above (no quarantine, test, mask in indoor/outdoor settings 10 days from date of exposure) regardless of your vaccination status. This guidance aligns with current Yale New Haven Health exposure guidance.

If I develop symptoms during my quarantine/self-monitoring period, what should I do?
Schedule a symptomatic test though the self-scheduling link immediately. CCRL can be reached at 203-432-6604 if you require further assistance. Remember, it is Yale policy not to return to campus if you have any COVID-like symptoms.

If I’m in quarantine or isolation, what should I do about work?
Please speak with your supervisor or HR Generalist about HR policies and job expectations during your isolation and quarantine period. It is standard Yale policy for your supervisor to be alerted when you are advised to isolate or quarantine, unless you opt out of this notification. For evolving information, please go to:

If I tested positive for COVID-19 in the past, do I still need to quarantine?
If you tested positive for COVID-19 in the last 90 days, quarantine is not necessary. We recommend that you continue to monitor your symptoms, promptly self-isolate if you develop symptoms, and call your healthcare provider or CCRL for further guidance. However, if you tested positive for COVID-19 more than 90 days ago, you should follow the guidance in the table above.

For any other questions or concerns, please contact or call CCRL at 203-432-6604.
