How does contact tracing work in identifying people who may have been exposed?

All individuals testing positive for COVID-19 are contacted and confidentially interviewed to identify people who came into close contact with the infected individual. University employees are trained on contact tracing by Johns Hopkins University and follow county, state, and federal guidelines. The CDC defines “close contact” as being within 6 feet of an infected individual for 15 minutes or more over a 24-hour period.

This trace assesses the class schedule, living situation, activities, work locations including offices and job sites, face-to-face meetings and any other situations that may have resulted in close contact from 2 days before the onset of symptoms or testing (if asymptomatic).

This process will evolve as we add technology to further support these efforts.
