Exposure and Quarantine Guidelines | COVID-19

In January 2022, the California Department of Public Health updated its guidelines for those who have been exposed to or test positive for COVID-19. Alameda County and CalOSHA have also adopted these guidelines.

As COVID-19 persists in our communities, please use the following guidelines to protect your health and those around you. If you feel ill or have tested positive for COVID-19, please do not come to campus. 

The table below from the Alameda County Department of Public Health has actions for those who test positive for COVID-19 and those who are exposed. Please note that Student Housing is following the isolation and quaratine guidelines for congregate settings and has a 10-day quarantine/isolation period.

The CDC considers that you have been exposed to COVID-19 if you have been within six feet of someone who tests positive for COVID-19 for a cumulative total of 15 minutes or more within a 24-hour period.

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).
