Inside the University buildings:

Masks are mandatory

  • in all shared spaces (reception areas, elevators, toilets, copy machines and printer areas, corridors and floors, kitchenettes etc);
  • in every situation where University staff is in contact with members of the public;
  • in shared offices where social distancing of 2 metres cannot be ensured if more than 10 persons are present;
  • during in-person meetings where social distancing of 2 metres cannot be ensured if more than 10 persons are present.

In classrooms:

  • Masks are mandatory for students during classes
  • Teachers who are fully vaccinated can choose to either wear a mask or not during teaching.

At public gatherings:

Masks are mandatory at public gatherings as of a certain number of attending persons (please refer to the section “Meetings, scientific and social events” below).

Mandatory wearing of masks does not apply to events organised under Covidcheck regulations (see below).

Please wear surgical masks that offer a high level of protection. Considering the risks posed by highly infectious new variants of the SARS-CoV 2 virus, the use of cloth masks, bandanas and scarves is not recommended. Shields and visors do not replace a face mask.

Please change your masks frequently (surgical one-way masks after 4 hours or when damp).

Special safety rules may apply in University labs.

Please learn how to use your mask properly: Watch the WHO’s instruction videos for medical masks.

Please bring your own masks. Limited stocks of masks are available at the reception desks to cover urgent needs.

Safety protocols in case of COVID-19

If a person is tested positive for COVID-19:

  • Please call 466644 5555 in case you test positive and contact to provide follow-up information.
  • Self-isolate immediately (stay at home, no contact with other persons, surgical mask compulsory in the presence of others).
  • Please provide 46 66 44 5555 or with a list of your high-risk contacts at the University over the past 48 hours before symptoms (or 48 hours before the date of your test if no symptoms occur until the date of the results).
  • Please follow the procedure indicated here: (EN) and fill out the form indicating your close high-risk contacts.
  • Contact your high-risk contacts (more than 15 minutes close contact at less than 2 metres distance, without or with incorrectly worn mask, car sharing without mask, meals taken with colleagues, etc.), inform them that you tested positive and that you shared their details (which should allow them to claim a test on day 6).
  • More details on isolation can be found here (EN).
  • Medical information will be treated confidentially. The University can however communicate on the occurrence of a case of infection in anonymous form to other employees/students, if necessary.
  • A person tested positive for COVID-19 who does not respect isolation measures or a medically prescribed quarantine faces fines under the law.

If a person is a high-risk contact of a positive person

  • Please check if you are high-risk: did you have exposure to the confirmed infected person for more than 15 minutes at close range (<2 metres) and without proper protection (no or incorrectly worn mask, car sharing without masks and meal with colleagues etc). Were you alerted by a confirmed positive contact of yours? Alternatively, were you alerted by the University or by the health authorities?
  • In any case, if you experience symptoms, please self-quarantine immediately and follow the procedure indicated here (EN). If necessary, seek medical advice by calling your doctor or by using the e-health platform econsult.
  • Stay at home for 7 days and avoid all non-protected contact with other people. Vaccinated persons do not need to quarantine. The same applies to persons who recovered from COVID-19 (for a maximum of six months following the recovery).
  • On day 6, get tested. If the test is negative the quarantine ends; for the next seven days, you are required to self-monitor and wear a mask when in contact with other people. If you have the reference number of the positive case, use this number to request a test.
  • If symptoms appear after 7 days, you must test again and self-isolate.

If you experience symptoms:

  • If you experience symptoms while at the University, please call the internal emergency number 466644 5555 in order to initiate the planned internal procedure (Personal Emergency Procedure).
  • Staff members or students with any symptoms of COVID-19 or who otherwise do not feel well must self-isolate and self-monitor. In case the symptoms persist, they need to call the doctor with whom they are registered here in Luxembourg or use econsult. They should not go to the doctor or to the hospitals’ emergency rooms if they suspect that they are infected with COVID-19. They should only go to the hospital emergency departments when they have a serious, non-COVID-19 related health problem. In case of an emergency, they should always call 112.

If a person in a class tests positive: 

During the winter semester 2021/2022, teaching and learning at the University takes place in hybrid format, combining in-person teaching in the class rooms with remote teaching.

If in one of these allowed in-person teaching environments a participant tests positive for COVID-19, all members of the class will switch to remote teaching for 14 days, unless the person who tested positive had no contact with other members of the class. “Class” designates a group of students that are registered for the course and who meet regularly to undertake a range of course activities such as lectures, lab work or travaux dirigés.

In case no contact occurred between the infected person and other members of the class, the class continues in hybrid mode as an in-person class, while provisions must be made to allow the COVID-19 positive person to follow the class and study remotely.

All classes must make provisions to accommodate students who are unable to attend in person teaching as described above. 

The 14-day period starts from the date of the last presence in class of the positive person.

Individuals in isolation (in case of confirmed infection), self-isolation or quarantine (in case of high-risk close contact) must follow the rules pertaining to their particular situation, as indicated by the public health authorities.

If a member of staff tests positive (outside of teaching):

In case a member of staff tests positive for COVID-19, other potentially affected members of the department or team will receive guidance and instructions as per the guidelines applied by the health authorities (self-monitoring, self-isolation or quarantine).

If a tenant of a student residence tests positive: A tenant of a student residence who tests positive must observe the general rules applying to persons with confirmed infections (see above). 

If a COVID-19 infection is suspected or, if a student in a residence has been tested positive for COVID-19, he/she must call 466644 5555 and provide follow-up information to The person needs to self-isolate immediately for a minimum of 10 days after the onset of symptoms (or upon confirmation of a positive test). See the student guidelines for more details.

Fellow tenants in residences may be required by the University to quarantine, depending on the particular situation (for instance in case of shared facilities or close contact with an infected person, several tenants may be considered high-risk contacts and may be required to quarantine). In such a case, the University applies the guidelines of the national health authorities.

  • Dean and vice-dean of the faculty;
  • Dean/vice-dean’s office is to inform the head of department, head of administration, study programme director and study programme administrator. 

If a staff member of the administration tests positive: 

In addition to the members of the COVID-19 ad hoc committee, the following persons are informed of the occurrence of a confirmed case (on an anonymous basis): 

  • Vice-rector or head of administration;

No formal maximum occupancy rates are in force for offices. Social distancing applies (see guidelines above).


Remote work

Work organisation, presence on campus and remote working must be agreed with the supervisors/managers.
