  • Suspected COVID-19 cases;
  • Confirmed COVID-19 cases;
  • Close contacts; and
  • Persons arriving or returning from a country/ area for which Switzerland and/or France impose a mandatory quarantine upon arrival or return (travel quarantine). These persons shall not come on to the CERN site for the duration of the quarantine imposed by France or Switzerland whichever is the longest. 

Suspected or confirmed COVID-19 cases and persons subject to medical quarantine shall declare their condition via the TRAMED tool and inform their supervisor.
