As of 1 June 2021, CERN has implemented a four-level COVID-19 scale, determining conditions for on-site access, telework and other measures that concern CERN members of personnel, contractors and visitors. The overarching objective remains to safeguard the health and safety of everybody on the CERN sites while enabling continued effective operation of the Laboratory.

The level in force at any given time may move up or down the scale. It is determined by the incidence rate in the local area, and a qualitative assessment by CERN taking into account, among other parameters, the number of confirmed cases at CERN, vaccination status in the local area, the testing campaign at CERN and the local presence of new variants of the virus.

The presence on site of all categories of personnel and visitors is supported by COVID-19-specific health and safety measures and instructions derived from memoranda by the Director-General.

COVID-19 helpline for support and information: Covid19.Helpline@cern.ch or +41 22 766 7777 from Monday to Friday (8 a.m. - 5 p.m.)

 

CERN is on Level 1 - Green from 14 March

The current applicable measures are as follows:

People with COVID-19-like symptoms* should still self-declare on TRAMED and may come on site until the result of the test carried out by the medical service is available: they are obliged to self-isolate only should their test be positive. While awaiting test results, where possible telework is recommended for those who can do so. If working on site, people should duly apply all protection measures, wear a mask and limit contact with others as much as possible. In the event of a positive test result, the duration of CERN site access prohibition will be communicated at the end of the TRAMED self-declaration process. Further, any person tested positive shall inform their close contacts. A flowchart to determine who is a close contact is available here.

If you are a close contact, you should self-declare your situation via TRAMED and follow the instructions that will be given to you by the Medical Service. As of 1 July, contact case follow-up will fully align with the French rules, i.e. only one self-test will be required 48h after the last contact with the positive person. These self-tests will be made available at the Medical Service for those who declare their situation on TRAMED.

Stratified testing for business continuity: self-tests are available in the CERN stores and can be ordered only by persons with corresponding departmental authorisation.

Note: a positive COVID-19 test result is not sufficient to register a sick leave request, only a formal certificate from your doctor will be accepted.

* Typical COVID-19 symptoms are: a persistent, dry cough, a sore throat, fever, i.e. a body temperature above 37.5 °C, a loss of taste and/or smell, muscle pain.
