Previously, Germany had been taking the approach of placing individual cantons on the list when case rates grew.
Now, all of Switzerland’s 26 cantons have been placed on the list – including border cantons.
The new list will apply as of midnight on Saturday, October 24th.
As well as Switzerland, Ireland, Poland and all of Austria other than Carinthia were also designated as risk areas.
The result of the decision is that anyone who enters from Switzerland must be tested on arrival in Germany.
This applies to returning German citizens as well as any other arrivals from a high-risk area, i.e. including Swiss nationals and residents.
The tested person must then quarantine until the test result comes through, relying on health authorities for guidance.
Germany's threshold for placing a country on the high-risk list is 50 infections per 100,000 residents over the previous seven days.
