Quarantine and Isolation

When exposed to someone who has tested positive for COVID-19 or after obtaining a positive COVID-19 test result, students, faculty and staff will need to quarantine or isolate in accordance with public health guidelines and College policy.

SMC Students

Students will be required to quarantine (when exposed to someone who has tested positive for COVID-19), isolate (after testing positive for COVID-19), or self-isolate (when experiencing any COVID-19 symptom) based on Public Health guidelines and Saint Mary’s College policy. Students will be required to immediately adhere to quarantine or isolation guidelines when necessary to prevent the spread of COVID-19. Quarantine and isolation are stricter versions of shelter-in-place.

SMC Employees

Employees must follow current county guidelines for quarantine (when exposed to someone who has tested positive for COVID-19), isolate (after testing positive for COVID-19). Employees are not allowed on campus until the conclusion of the prescripted quarantine or isolation period.


SMC students and employees will need to remain in isolation or self-isolation until 3 days have passed since experiencing any symptoms of COVID-19 (as long as this is at least 10 days from onset of symptoms). 

SMC students and employees will need to remain in quarantine until 14 days have passed since exposure AND you have experienced no symptoms of possible COVID-19. 

If you are placed in mandated quarantine or isolation, it is your responsibility to reference the complete Contra Costa County Health Services instructions for quarantine, isolation, or self-isolation—whichever applies to you. It is important to reference the most up to date version of these guidelines, which are subject to change. Monitor yourself for COVID-19 symptoms (if in quarantine) or for worsening symptoms (if in isolation or self-isolation), and notify the Health & Wellness Center or your primary care provider of changes. Clinicians are here to help guide you during this time.
