Help trace COVID-19: act early - self-declare/self-evaluate on Tramed


In light of the stricter measures announced by CERN’s Host States (France and Switzerland) to confront the escalating number of infections in their countries, CERN is adapting its framework for on-site activities and telework. The overarching objective remains to safeguard the health and safety of everybody on the CERN sites while enabling continued effective operation of the Laboratory, as far as feasible.

The return on site of all categories of personnel is supported by COVID-19-specific health and safety measures and recommendations, which are collated and regularly updated on this webpage.  

These are based on the Memorandum from the Director General and its associated documents available here.

Frequently Asked Questions (FAQ) for CERN personnel, are available on a dedicated page.
