Members of CERN personnel who have either tested positive for COVID-19, show COVID-19 symptoms or think they may have contracted the virus (via close contact with an infected person, for example), are requested to inform the Medical Service (Tel: + 41 22 766 7777 or medical.service@cern.ch) urgently, in order to ensure that all possible close contact are identified in the early stages of the disease and thus effectively break the chain of transmission. The same applies if any household members show symptoms associated with COVID-19.
