Updates to University Policies and Mitigations

Visitor Policy Ended

Visitors to the University are expected to follow CDC and NJ Department of Health guidance for individuals who test positive for COVID-19 or were in close contact with someone who tested positive in the past 10 days, including isolation and mask requirements.

The Visitor Policy enacted for COVID-19 mitigation is no longer in effect. 

COVID-19 Vaccine Mandate Lifted

The University strongly recommends that students, faculty, staff, and researchers stay up-to-date with COVID-19 vaccination and boosters. COVID-19 vaccines continue to be effective at reducing the risk of severe disease.
However, the University is no longer requiring the primary vaccine series (one dose of a single dose vaccine or two of a two-dose vaccine) for the University community. The COVID-19 Vaccine Policy first endorsed on June 2, 2021, is no longer in effect. 

COVID-19 Testing Laboratory Closing

The campus laboratory certified to conduct PCR testing for COVID-19 for members of the University community will close in June. The last day that the laboratory will process samples will be June 6, 2023. 

Isolation is Still Required

If you have symptoms consistent with COVID-19 (runny nose, cough, fever, body aches, etc.), you should test for COVID-19. If you test positive, the NJ Department of Health still requires people to self-isolate for at least 5 days, staying out of work, classes, activities, events, etc. in accordance with CDC guidelines

After 5 days, if your symptoms have improved and you have been fever-free for at least 24 hours, you may return to work, classes, and other events as long as you wear a mask at all times around other people for 5 additional days.

There is no indication from public health officials that the expectations for people who have tested positive or have been in close contact with someone who has tested positive will change any time soon. 

University faculty and staff continue to be able to use COVID-19 days to cover this isolation time or to care for someone who is isolating.

Visit the Isolation/Exposure webpage for more information.

Face Coverings

Face coverings remain optional in non-instructional spaces; however, instructors may require masks in classrooms, labs, and other teaching environments, so students should carry a mask with them at all times. For more information on face covering guidance, visit EHS’ website.

With a valid student ID, students can pick up up to 10 KN95 masks at the following locations:


  • All Residential College offices: weekdays 11 a.m. to 4 p.m.


  • Graduate School at Clio Hall: Monday through Thursday 9 a.m. to 4:45pm
  • Graduate College Porter’s Lodge: weekdays 11 a.m. to 4 p.m.
  • Lakeside Apartments Main Office: regular business hours

Up to 10 per person. Cannot pick up masks for another person. Must show valid student ID.
