Procedures for positive cases or their contacts

Fall 2022 COVID-19 Guidelines(as of August 1, 2022) 

Positive Case 

If you test positive on a Rapid Antigen Test (RAT) self-test, inform Mason Korea Emergency, Health and Safety (EHS) immediately. You can use this form. Confirm the positive test with a Covid test at a local clinic. If the test is positive, quarantine for 7 days. Day 1 begins with the test day of the positive RAT (not the day you received your results).  After 7 days, the required quarantine period is complete. However, the government recommends monitoring your health for an additional 3 days, and always wearing a KF-94 or higher mask. Please also take care to wear a mask and limit your exposure to others while you are awaiting the results of your test at the local health center. 

For quarantine location information and other considerations, please see below. 

Close Contact 

Close contacts are those who were within 2 meters of an infected person for more than 15 minutes while not wearing masks. Family members are always close contacts. 

If you are a close contact, take a RAT immediately and then two days later. If your close contact was another member of the Mason community, Mason Korea will supply your tests, if available. Contact for availability. Monitor for symptoms. If your test results are negative, there are no restriction from campus. However, please do not eat, drink, or smoke on campus with others. 

Students Who Test Positive 

If you test positive at a local clinic, you will be asked to quarantine for 7 days. 

If you live on campus and have a roommate, notify them. IGC will place your roommate in a new, vacant room and ask them to take a RAT test. 

Students who have residences within three hours of Mason Korea will be asked to quarantine at their residence. 

Students who have residences over three hours away Mason Korea, or those verified as unable to quarantine at home will be supported with an off-campus quarantine location. 

Mason Korea instructors will make accommodations for students in quarantine. No student should come to campus for fear of missing classwork. 

Faculty Members Who Test Positive 

If you test positive at a local clinic, you will be asked to quarantine for 7 days. 

If you live on campus in the Faculty Apartments or in a Guesthouse apartment with a kitchen and bathroom, you may quarantine in your apartment. 

If you live on campus in a family room in Dormitory A or in a Guesthouse apartment without a kitchen and bathroom, we will ask you to quarantine off campus and will provide support to locate off-campus housing during your time of quarantine. 

Please follow your instructional continuity plan to ensure the continuous instruction of your classes. 

Staff Members Who Test Positive 

If you test positive at a local clinic, you will be asked to quarantine for 7 days. 

Please arrange with your supervisor and co-workers to handle your duties, should you be unable to telework. 

Instructional and Work Considerations 

The above actions refer to individual cases. Mason Korea has additional plans depending on the number of positive cases at any one time. The table below provides those actions. The percentages refer to the number of cases or persons quarantining relative to the total number of our Mason community, including students, faculty and staff. That number is approximately 740.  

We start the semester at Level One. 




In-person events 

Telework employees 




Less than 10% positive cases 







10~20% positive cases 


Small groups 






20%~ positive cases

Fully Online 




Not allowed 

* The above criteria is subject to change based on government recommendations  

If we move to Level Two, we will reduce the density of students in the building through hybrid instruction. More details regarding the structure of hybrid instruction will be forthcoming. 

Unlike in previous semesters, we will revert to a lower level if the case or quarantine numbers fall below the relevant thresholds. 

We're Here to Help 

If you have questions, please contact Mason Korea’s Emergency, Health and Safety (EHS) unit at or 032-626-5555. However, we ask that you be sure to review the information above first, so that our staff can focus on supporting people who test positive or other urgent situations. 

Please also note that changing knowledge, circumstances and government policies drive rapid changes in our guidance regarding disease transmission prevention.  For this reason, the procedures detailed are subject to change.
