Coronavirus updates

This page is updated regularly; the latest update is at the top.

Update 17 september: Coming to the University? Do the corona check first!

Do the corona check before you come to study or work at the University. Answer the five questions on the checklist to see whether you can come. Stay at home if the check tells you to. This is to protect the health of students and staff and ensure the University can stay open.

If the checklist indicates that you are allowed to come to the University, always keep 1.5 metres away from others and avoid busy places, in the buildings too. Also follow the instructions on the signs and stickers and from our staff, and read the Campus Protocol thoroughly.

Update 4 September: What to do if you contract the coronavirus, Campus Protocol updated

New version of Campus Protocol online

The academic year has now started and we are able to welcome many of our students and lecturers back in our university buildings. As more people are coming to the university, we will also have to deal with virus infections among our students and staff. Understandably, this raises some concerns and questions within our organisation, including what to do in the event of an infection. The Campus Protocol has therefore been updated to include this information; a new version of the protocol is now available.

What should you do if you contract the coronavirus?

If you test positive for coronavirus, we ask you kindly to report this to us. Students can inform their study adviser and staff can inform their manager. Together – students and staff – we are a community where we have close contact with one another. It is in the best interests of everyone’s health and safety to know if there are clusters of infections – whether these are confirmed or threatened.  This is why we are asking you to let us know if you test positive for coronavirus.

There is no obligation to report infections. They are not recorded and there is no database where information on infections is kept. The information on infections will only be passed on to our Security Department, and always in anonymous form, so that if necessary we can discuss with the Municipal Health Authority (GGD) any additional measures that may be needed. A logical consequence of this is that we will not publish on our website any overview of infections, nor will we communicate about infections in any other way throughout the university.

If everyone keeps to the Campus Protocol - that is: don’t come to the university if you have any symptoms or if you have returned from a country with a red or orange travel advisory, keep a distance of 1.5 m between people, and wash your hands regularly -  the risk of infection is low. Together, we will make sure the university remains a safe and healthy workplace for our fellow students and colleagues, and at the same time we will play our part in fighting coronavirus. 

Update 25 August: New Campus Protocol adopted

The University’s new Campus Protocol enters into force on 31 August. This lists the rules and regulations for studying and working at Leiden University. From the start of the new academic year, we will be able to provide a limited amount of on-campus teaching once again. With more students and staff in our buildings, it is important that everyone is fully aware of who may come to the University and what the rules of conduct are.

Update 21 August: Associations need permission for introduction and recruitment activities

If you are planning an activity to recruit or introduce new members to a study, student or sport association, you will first need permission from the Security Region* and in some instances the University too. This is because of coronavirus. Read more in this announcement

Update 19 August: Quarantine period reduced to ten days

In line with the government measures announced on 18 August, Leiden University is also reducing its quarantine period to ten days. Students and staff who have recently returned or arrived from a country or region with a red or orange travel advisory (which includes an advised period of quarantine) may not come to the University for ten days. 

For the latest travel advisories, see nederlandwereldwijd.nl.

Update 18 August: Preparations for the new academic year: campus protocol and ventilation

Campus protocol

The new 2020-2021 academic year will begin on 31 August. Fortunately, we will be able to resume a limited amount of teaching in our buildings. This means that many students, lecturers and other staff members will once again be able to come to the University. In anticipation of this, adaptations have been made to our buildings over the past months, including fitting sneeze screens, creating one-way systems, posting instructions at lifts and staircases, determining the maximum number of people per room and providing extra options for hand disinfection. If you come to one of our buildings, please follow the instructions.

We are also working on a campus protocol that briefly explains all of our guidelines on work and study at the University. The protocol is being discussed this week and will be published on 25 August. In the run-up to and at the start of the new academic year, we will inform our students and staff in various ways of the rules that apply.


If you have recently travelled abroad, check whether you will have to quarantine. Please note: University policy is stricter than government policy. If the government advises quarantining on your return from a specific country or area, students and staff may not come to the University. 

In principle, the government advises quarantining on your return from countries with a red or orange travel advisory because of corona. The latest travel advisories can be found on nederlandwereldwijd.nl. Here you will see whether quarantine is advised. If the government does advise quarantining, you may not come to the University for 14 days.


All of our teaching rooms are fitted with a mechanical ventilation system. The ventilation is good in the spaces that have such a system. These systems are now starting one hour earlier and stopping one hour later than usual. They do not recirculate air.  All the ventilation systems are running above capacity as the corona measures mean fewer people are present in our buildings and rooms. Some workspaces and meeting rooms do not have mechanical ventilation systems. These rooms should be ventilated by opening windows (if at all possible).

Do not use small air-conditioning units or fans if more than one person is working in the room. Small air-conditioning units that are used to cool a single room usually cool the air and blow it back into the same room. Fans also recirculate air within a room. You can use them in front of an open window to improve the circulation of fresh air in the room, but do make sure that this fresh air is not being blown past one person towards another.

Update 7 August: Introduction weeks to go ahead with restrictions, but no in-person introductions to student associations

On Thursday 6 August, the government announced measures relating to the introduction weeks for universities and student associations. These can go ahead under certain conditions. For the students of Leiden University and Leiden University of Applied Sciences this means the following:

The EL CID, HOP and OWL introduction weeks can go ahead. Very careful preparation has gone into these programmes in recent months so that they already take into account all the necessary measures. Intensive coordination has also taken place with the local councils and the Municipal Public Health Service. As a result, programmes have been devised that include an online component and in all three weeks an in-person component of at least one day. For this part of the programme students will come to Leiden or The Hague in small groups to meet one another, get to know the city and their programme and find out more about student life. These days will not have an evening programme and all the activities will be arranged so that the 1.5-metre distance and other precautionary measures are complied with at all times. This means that the programmes for our introduction weeks already meet the restrictions set by the government.

The in-person introduction to the student associations cannot go ahead. The student associations will each inform their own members and aspiring members. Obviously, the university is in close contact with the student associations.

We strongly urge our students, both the new first-year students and our current bachelor’s and master’s students, to comply with the corona measures, to refrain from organising activities outside the official programme and to limit their social contacts. This will help reduce the risk of a further spread of the virus.
