Quarantine and Isolation

Quarantine and isolation help protect the public from those who may have COVID-19 by preventing further exposure.

  • Quarantine separates and restricts the movement of people who were exposed to COVID-19 to see if they become sick.
  • Isolation separates people who have gotten a positive diagnosis of COVID-19 whether or not they are experiencing symptoms from people who do not have COVID-19.

Princeton has prepared our campus to offer adequate space for those students who need private locations for quarantine or isolation.

Quarantine Protocols During the Semester

UPDATE 4/6/21: Per NJ guidelines, which follow updated recommendations from the CDC, individuals no longer need to quarantine after domestic travel or exposure if they are fully vaccinated.

If a student or staff member is required by University Health Services to enter quarantine during the course of the semester for any reason, there are strict guidelines that must be adhered to. Please see the fact sheets (in the Related Documents section at the bottom of the page) which vary depending on your status. Quarantine that is required due to exposure to a potentially infected or infected person, or due to travel outside of New Jersey, is a default 10 days. 

Travel within New Jersey (even if outside the Mercer County/Plainsboro region) does not require quarantine upon return to campus. However, if you are an undergraduate, travel outside of Mercer County must be approved by your Director of Student Life. 

If you have questions regarding quarantine guidelines, please email communityhealth@princeton.edu.  A reminder: violations of quarantine or isolation are very serious threats to public health and may trigger disciplinary consequences. 

Isolation for Students

If a student is sick with COVID-19 symptoms or tests positive for COVID-19, University Health Services will work with that person to isolate and monitor their health until they are cleared to resume normal daily activities. Students on campus may need to isolate in designated rooms on campus. Meals and support services will be provided during isolation.

As with quarantine, violations of isolation are very serious threats to public health and may trigger disciplinary consequences, including involvement of local, off-campus public health authorities. 

For more information on how students in isolation can continue to take part in academics, see the FAQ on the Spring 2021 website.

Please see the Related Documents section at the bottom of this page for the fact sheet for students isolating on or near campus. 

Isolation for Employees

Employees who are mildly ill with COVID-19 can isolate at home during their illness.
