If you have to quarantine, you will have to stay at home or in appropriate accommodation for 10 days starting from the date you were last in contact with the contagious person, or from the day after your arrival in Switzerland.
As of 8 February 2021, the 10-day quarantine period may be shortened if the person is tested after seven days (PCR test or rapid test) and the result is negative. This new rule applies both to Swiss residents having to quarantine and to all travellers entering Switzerland from a country or territory at risk. Travellers entering Switzerland from a country or territory at risk must produce evidence of a negative PCR test taken less than 72 hours before arrival, and then quarantine for ten days, as has been the case up to now. They may, however, come out of quarantine after seven days if they take a rapid (lateral flow) or PCR test and the result is negative.
People entering Switzerland by air from a country or territory without a high risk of infection must also be able to present a negative PCR test result.
From 31 May, people who have been fully vaccinated or have recovered from coronavirus within the last six months are exempt from all health-related measures at the Swiss border. Caution: these exemptions do not apply if you have travelled from a country that is on the FOPH list of risk countries due to a variant of concern.
