Carleton College Threshold Action Levels

Carleton College’s senior leadership team is continuously monitoring the public health metrics of the campus in the context of county, state, and national data. We have identified COVID-19 Action Levels to help describe potential transmission scenarios and how the College would plan to operate at various stages. 

These risk levels take into account the important work our campus community is doing to mitigate the spread of COVID-19 through the behaviors defined in our campus covenant. Impacts on campus operations, residential life, and testing are adjusted at each of the low, medium, high, and critical action levels (and each level is additive: e.g., the actions at Level 3 include also the actions from Levels 1 and 2). The Threshold tool also incorporates both internal and external measures that together help inform movement from one action level to another. It is important to note that the increase or decrease in a single measure is not likely to create a shift to a new action level; rather several measures must be trending in a similar direction to spur a shift. 

As we’ve learned since the beginning of the pandemic, the science regarding COVID-19 is continually evolving, and subsequently, we may change or amend specific threshold measures as public health guidance and recommendations are updated, new testing technologies emerge, and we implement learnings from others in higher education. Any changes will only be considered where they result in safer outcomes for the Carleton community.

Transmission Scenarios

 
Action Level 1: LowAction Level 2: MediumAction Level 3: HighAction Level 4: Critical
Transmission ScenariosA small number of individuals have tested positive and contact tracing suggests that exposures are confined to a small number of people. Through contact tracing, the situation can be contained through isolation and quarantine measures.Cases are occurring in what appears to be a defined population (residential hall, academic/administrative building, team, classroom, event, etc.). Due to the number of cases identified, the confidence in the ability to accurately complete contact tracing is moderate. More widespread cases are occurring (multiple unrelated cases, in a short period of time on campus in multiple locations, etc.), and there is low confidence in the ability to identify and trace close-contacts.The situation has escalated to the point where ongoing campus transmission is occurring at a significant rate. There is no realistic strategy to contain or control the situation and it is estimated that it will take a month or more to decrease on-campus transmission. Given the timing in the academic calendar, campus operations will be significantly limited to reduce the risk of ongoing transmission.

Campus and Residential Life Impacts

 LowMediumHighCritical
Impacts to CampusInfected individuals are isolated and close contacts are quarantined. Any potentially contaminated areas are disinfected. Communication is made to the community regarding the identification of a cluster of illnesses. Discontinue operations in select programs or areas but no impacts to campus-wide operations. Some programs or functions may need to suspend face-to-face activities. Campus comes to a pause to allow programs to move online. External access to campus is more restricted and employees work from home whenever possible. Based on the specifics of cases occurring, a remediation plan will be implemented to mitigate the spread of the disease and resume normal operations in approximately 1 to 4 weeks. Campus operations limited to only the most essential services, continuing until we've limited the number of people on campus as much as possible.
Impacts to Residential LifeAny common areas potentially affected will be cleaned and disinfected. All other residential life activity remains unaffected.If the increase in cases is associated with a residence hall, house, or a floor in a residence hall, a hall, house or floor-specific quarantine may be required. Access to common spaces in affected areas may be limited. All residents are instructed to "shelter-in-place" in residence halls and campus housing. In consultation and coordination with MDH and LPH, a move-out process will be initiated. Students will leave campus with their possessions as part of a formal check-out process. Students in isolation or quarantine will leave campus in consultation with local and state authorities.
TestingIn consultation with MDH, LPH, and other resources, targeted testing may be warranted.Use of asymptomatic surveillance may be warranted.Campus-wide surveillance testing of the entire population may be conducted.Working with MDH and LPH, campus-wide surveillance testing of the entire population will be conducted to ensure safe travel and minimize the risk of further infection outside of the Carleton Community.

Interpreting this Data

  • Data is updated weekly on Wednesdays.
  • The 14-day infection rate is the rate of lab-confirmed cases of COVID-19 over a 14-day period among all students, faculty and staff who are approved to live, learn or work on campus. For Fall Term 2020, the total campus population is 2,179 people. The 14-day infection rate includes cases of COVID-19 confirmed through testing outside of Carleton. 
  • The number of new confirmed cases is tallied weekly and reflects known data for all Carleton students, faculty, staff, and contractors who are approved to live, learn, or work on campus. This number includes cases of COVID-19 confirmed through testing outside of Carleton. 
  • Surveillance testing began Sept. 25, 2020, and is conducted weekly on 300 randomly selected members of our on-campus community. This statistically based sampling plan was established to give us a clear picture of where we are as a campus each week. The actual number of people tested may be slightly lower or higher each week.
  • The average number of close contacts is tallied weekly. A close contact is defined as any individual who was within 6 feet of a confirmed case of COVID-19 for at least 15 minutes starting from 2 days before illness onset (or, for asymptomatic cases, 2 days prior to positive test administration) until the time the confirmed case is isolated.
  • Isolation and quarantine occupancy is calculated using the denominator of 90 dedicated campus spaces for isolation and quarantine, and reflects total use of this space over the course of the week. Occupancy includes new and existing student cases that require isolation, students who require quarantine due to contact with a confirmed case on or off campus, and symptomatic students who require isolation.
    • Isolation means separation, during the period of communicability, of a person infected with a communicable disease, in a place and under conditions so as to prevent direct or indirect transmission of an infectious agent to others.
    • Quarantine means restriction, during a period of communicability, of activities or travel of an otherwise healthy person who likely has been exposed to a communicable disease to prevent disease transmission during the period of communicability in the event the person is infected.
