Contact Tracing FAQs

Why wasn’t I contacted by the Yale Contact Tracing team?
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.

If you think you meet the criteria above but were not contacted, please schedule a test, monitor your symptoms and call the Campus COVID Resource Line (CCRL) at 203-432-6604 who will provide further guidance.

If I receive a negative test result, do I still need to quarantine?
Yes. Even though you tested negative for COVID-19, it can take several days since you were exposed to test positive if you are infected. It is important for you to remain in quarantine, and test as recommended by the contact tracers.

If I was vaccinated for COVID-19, do I still need to quarantine?
It depends on when you were vaccinated, and whether you are fully protected. If you have received both doses of a COVID-19 vaccine, your Contact Tracer will work with you to see if you do not need to quarantine based on the dates you were vaccinated.  If you have not received both doses (see guidance for unvaccinated close contacts), you will still need to quarantine. If you have received the vaccine, and are 14 days out from your final dose (see guidance for fully vaccinated close contacts), then you do not need to quarantine. However, you will need to test, monitor for symptoms, and self-isolate if you become symptomatic. Vaccines are new, and we know that they protect persons from developing severe disease. However, we are still learning about how vaccines prevent transmission, and they may take a while to take effect. Therefore, people who are vaccinated still need to test, wear a mask, wash hands frequently, and practice physical distancing.

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, and promptly self-isolate if you develop symptoms. However, if you tested positive for COVID-19 more than 90 days ago, and are not vaccinated, you do need to quarantine because your natural antibodies may no longer be effective, and you could be at risk for reinfection.

How long is my quarantine/self-monitoring?
Yale has aligned with CDC guidance and the State of CT Department of Public Health  and recommends 10 days of quarantine/self-monitoring since date of last exposure to the infected individual, as long as you do not develop symptoms. Through Yale, you will be referred for testing, detailed guidance on current testing recommendations can be found here. Please remember that a negative test does not mean your quarantine/self-monitoring ends early – there is no ‘test-out’.

If I develop symptoms during my quarantine/self-monitoring period, what should I do?
Call your healthcare provider and schedule a symptomatic test through CCRL or through the self-scheduling link immediately. CCRL can be reached at 203-432-6604. 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:

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