Protect Purdue Glossary of Terms

Updated September 3, 2020

Quarantine: Keeping someone who might have been exposed to COVID-19 away from others. Quarantine helps prevent spread of disease that can occur before a person knows they are sick or if they are infected with the virus without feeling symptoms. Individuals in quarantine should stay home for 14 days, separate themselves from others, monitor their health and follow directions from the Protect Purdue Health Center. You may leave your home to get grab-and-go food and eat at home. For more from the CDC on quarantine, go here.

Isolate/Isolation: Separating people infected with the virus (those who are sick with COVID-19 as well as those with no symptoms). Individuals with active cases are asked to isolate for at least 10 days after symptoms begin and 24 hours after their fever has broken, without the use of fever-reducing medications, and with the improvement of other symptoms. Individuals in isolation must not leave their home except for emergencies. They should monitor their health and follow directions from the Protect Purdue Health Center. For more from the CDC on isolation, go here.

Symptomatic: An individual who is exhibiting symptoms of the coronavirus — fever of 100.4 or higher, cough and shortness of breath are the main symptoms of COVID-19. For the latest on symptoms from the CDC, go here.

Asymptomatic: Not showing any symptoms (signs of disease or illness). Some people without any symptoms of COVID-19 can still have and spread the coronavirus, however. They’re asymptomatic, but contagious.

Online Option: University’s academic plan to offer a robust lineup of fully online courses for students who cannot or choose not to come to campus because of the COVID-19 pandemic but desire to start or continue their Purdue studies virtually instead of in person as a residential student. Online offerings currently include an extensive course catalog, specifically most high-enrollment courses. Instructional designers and video teams collaborated with faculty to support adaptation of many courses to the online environment. All online courses have the same content,  learning outcomes and rigor as their on-campus counterparts. Courses are tailored for an online environment and for participation from anywhere in the world.

Hybrid/HyFlex: Hybrid courses combine face-to-face (in person) delivery of content and activity with online content and activity, such as videos of lecture content, structured online group activities or simulated lab experiments. In typical hybrid courses, the instructor makes most of the choices, such as when the class meets in person or online as well as the percentage breakdown of each format during the semester (50/50; two-thirds online/one-third face-to-face, for example). HyFlex follows the hybrid model, but learners can switch between in-person and online completion of activities and assessments at will — for example, in-person or via virtual classroom (WebEx, Zoom, Microsoft Teams, etc.) in real time or from a recording while completing online activities later.

Resilient Pedagogy: An approach to course design that anticipates disruption and blends in-person, hybrid and online features to ensure continuity of instruction for students and faculty in any eventuality, such as if an instructor or student needs to quarantine or isolate because of COVID-19. At the same time, these courses meet the same high standards of rigor and excellence of in-person instruction. The Impact X+ program supports instructors to design their courses to be more resilient and to preserve the course integrity during external challenges, with special focus on the unique needs of large-lecture, lab-intensive, experiential, writing-intensive, and project/team/design courses.

De-densification: Reducing the number of people congregating in a given location to decrease risk of disease spread. For classrooms and living spaces, this means redesigning or re-creating spaces  to allow for safe social distancing — limiting, for example, capacities of large lecture halls to an occupancy of no more than 150 students. For more about Purdue’s de-densification plans, go here.

High-Risk Contact: Defined as any individual who was within 6 feet of a COVID-19-infected person for at least 15 minutes, when neither person is wearing personal protective equipment (PPE) such as a mask. This would be from 2 days before the onset of the illness until the time the infected person who has tested positive for COVID-19 is cleared from isolation. For asymptomatic patients who test positive for COVID-19, they would be considered infectious at least 2 days prior to the date of their COVID-19 test.

Low-Risk Contact: Defined as any individual who was around a COVID-19-positive person for less than 15 minutes at a distance of more than 6 feet and wearing masks.

Contact Tracing: Process for identifying individuals who have come in contact with someone who has been diagnosed with COVID-19. The purpose of contact tracing is to provide early medical intervention with the contact, which may interrupt or prevent spread of the disease.

Sampling vs. testing: Sampling is the scientific process of collecting a specimen from an individual to determine whether an infection with SARS-CoV-2, the virus that causes COVID-19, is present. This is done most commonly through a swab or saliva specimen. The sample is then analyzed for the virus at a diagnostic testing laboratory. In this case, negative (or “not detected”) is a good thing. Testing is the commonly used phrase for this process, start to finish.

Congregate Housing: Common at college campuses, this is a type of housing in which each individual or family has a private bedroom or living quarters but shares a common dining room, recreational room or other facilities. For COVID-19, guidelines have been established to help owners, administrators or operators of shared, or congregate, housing facilities — working together with residents, staff and public health officials — prevent the spread of the coronavirus. At Purdue, this includes housing ranging from some residence halls and apartments to cooperatives, sororities and fraternities. Those living and working in congregate housing may have social distancing challenges because residents often gather closely for social, leisure and recreational activities, shared dining, and/or use of shared equipment, such as kitchen appliances, laundry facilities, stairwells and elevators. For tips on how to protect yourself in congregate housing settings, go here.
