How is “close contact” defined?
Congruent with updated state and CDC definition of a close contact of a COVID-19 case, a close contact is defined as someone who:
- is within six feet of a positive COVID-19 person/case for 15 minutes or more while indoors over the course of a 24-hour period, starting two days before the onset of illness and while the case is symptomatic; or
- is within six feet of a positive COVID-19 person/case for 15 minutes or more while indoors during the 48 hours before their test was taken or anytime in the 10 days after the test; or
- provided care at home to someone who is sick with COVID-19; or
- Had direct physical contact with (touched, hugged, or kissed) a positive COVID-19 person; or
- shared food, or eating or drinking utensils with a positive COVID-19 person; or
- was sneezed or coughed on by a positive COVID-19 person, transmitting respiratory droplets to them.
In all cases, the decision to quarantine is a clinical decision made by a Tufts clinician in collaboration with the university’s contract tracing team and the local boards of health. Any student, faculty, or staff member instructed to quarantine is expected to fully cooperate with the contact tracing process and strictly adhere to all instructions.
