If the university determines that a member of the community has a confirmed case of COVID-19, and it is suspected that you may have been within six feet of this individual for a total of 15 minutes or more during the infectious period, you will be contacted directly by Student Health & Counseling Services (for students) or Human Resources (for employees).
