The Campus Risk Status level is based on a comprehensive analysis of various indicators, including, but not limited to, the University’s COVID positivity rate. Learn more about the campus risk status.

Weekly testing metrics represent asymptomatic testing data only; asymptomatic testing and tests completed at McCosh or off-campus clinics are reflected in the Daily Positives report, below. Weekly testing data are updated on Mondays to report the previous week, Saturday to Friday.

The Campus Positivity Rate is a Princeton-specific metric and represents one of multiple factors that helps to determine the Campus Risk Level. Learn more about the campus positivity rate.

The University has granted a limited number of medical and religious vaccination exemptions.

Campus Risk Status Levels | Definitions and Potential Mitigations

The Campus Risk Status is based on an analysis of a combination of both campus and neighboring community indicators, including number of cases, positivity and transmission rates, cluster cases, vaccination, testing and care capacity.

Definitions

Green light, indicates low risk level
Low Risk
Yellow light, indicates low-moderate risk level
Low to Moderate Risk
Orange light, indicates moderate-high risk level
Moderate to High Risk
Red light, indicates high risk level
High Risk

Factors of a Low risk status include: Cases are infrequent or sporadic and low compared to our predictive model. Containment of isolated cases. Local community case rates are low. The health risks from infection are reduced due to high vaccination rates.

Factors of a Low to Moderate risk status include: Case rates are low to moderate or there are higher cases due to contained clusters. The health risks from infection are reduced due to high vaccination rates. There is a potential for increased cases or transmission due to higher local community case rates, transmission rates on or around campus, or higher campus population or activity level (e.g., Move-in or Commencement).   

Factors of a Moderate to High risk status include: Case rates are moderate to high, transmission rates are high, and/or there is reduced capacity for patient care on campus or in local hospitals, isolation space, testing, contact tracing, or other services. There is a potential for increased cases or transmissions due to higher local community case rates, transmission rates on or around campus, or higher campus population or activity (e.g., Move-in or Commencement). Multiple factors forecast that the rate of infection may continue to increase.

Factors of a High risk status include: Case rates are high and transmission rates are high, affecting our ability to provide patient care on campus or in local hospitals, isolation space, quarantine, testing, contact tracing, or other services. There is a potential for increased cases or transmissions due to higher local community case rates, transmission rates on or around campus, or higher campus population or activity (e.g., Move-in or Commencement). Multiple factors forecast that the rate of infection may continue to increase.

Mitigations for all or parts of campus may include but are not limited to any or all of the following:

  • Face coverings guidance and other public health measures.
  • Participation in asymptomatic testing.
  • Gatherings conform to requirements listed in the Guidance on Events and Conferences and comply with government limitations.
  • Visitors may be limited on campus, per Visitor Policy.
  • Vaccinated and unvaccinated individuals may be subject to different requirements and restrictions.
  • Travel restrictions may apply

 

Mitigations for all or parts of campus may include but are not limited to those listed above and any or all of the following:

  • Additional face coverings requirements.
  • Additional limitations on gatherings.
  • Reduction in visitor exemptions.
  • Additional restrictions on indoor dining.
  • Increased frequency of testing for some populations.
  • Increased travel restrictions.

 

Mitigations for all or parts of campus may include but are not limited to those listed above and any or all of the following:

  • Frequency of testing may be increased further for some populations and/or expanded to others.
  • Targeted restrictions of mobility off campus.
  • Targeted quarantine for campus locations with clusters of infection.
  • Specific employees may be asked to work remotely.
  • Grab-and-go meals or other dining limitations.
  • Targeted or temporary hybrid or remote learning.
  • Targeted or temporary de-densification with remote work.
  • Changes to research operations level per the University’s plan for the Phased Resumption of On-Campus Research.

 

Mitigations for all or parts of campus may include but are not limited to those listed above and any or all of the following:

  • Frequency of testing may be increased even further for some populations.
  • Classes moved to online only.
  • Additional employees may be asked to work remotely.
  • Broad or targeted quarantine of students living in campus housing.
  • Research operations moved to a more restrictive phase.
  • Further restrict in-person gathering, event, and meetings of any size.

Campus Positivity Rate

The Campus Positivity Rate is a Princeton-specific metric and represents one of multiple factors that helps to determine the Campus Risk Level. Princeton University public health professionals monitor case rates daily and use the ranges below to assign a weekly positivity rate to the campus population.

The Campus Positivity Rate is reported weekly and the levels are rated:

  • LOW: Positivity rate is 0 to 0.1%
  • MODERATE: 0.11 to 0.5%
    • Our mitigation efforts were built around this range.
  • HIGH: More than 0.5%
    • Above this rate, our ability to provide isolation, quarantine, contact tracing, etc. may be compromised.
