UPDATE: Which countries and regions are now on Switzerland's quarantine list
Currently, there are 66 countries or regions on Switzerland's 'high risk' list.
This report has been updated on October 10th and is subject to change.
Throughout the pandemic, Switzerland slammed shut its borders - even those which had not been closed for more than half a century.
Only citizens, residents and cross-border workers were allowed to cross into Switzerland during the pandemic.
So who is allowed to enter Switzerland and under what circumstances? Unless you fit into the above three categories, that all depends on where you are arriving from.
While borders have again been allowed to open, arrivals from certain 'high risk' countries will need to quarantine for ten days on arrival in Switzerland.
Any country with more than 60 infections per 100,000 people over the previous 14 days is deemed high risk by the government and will be placed on the list.
The issue becomes more complicated with border countries. Countries which share a border with Switzerland will have specific regions placed on the list, rather than the entire country.
Which countries - and regions - are on Switzerland's 'high-risk' list?
Quarantine requirements will apply from certain high-risk areas from July 6th onwards. The list of countries is regularly updated by Swiss health authorities.
There are dozens of countries on the list, along with four border countries (France, Germany, Italy and Austria) where arrivals from certain regions must quarantine.
As at October 12th, the list includes dozens of countries or parts of countries: Albania, Andorra, Argentina, Armenia, Aruba, Austria (several regions), the Bahamas, Bahrain, Belgium, Belize, Bosnia and Herzegovina, Brazil, Cabo Verde, Canada, Colombia, Chile, Costa Rica, Croatia, Denmark, Ecuador, El Salvador, Eswatini, Faroe Islands, France (several regions), Georgia, Germany (Hamburg and Berlin), Gibraltar, Guam, Guatemala, Honduras, Hungary, Iceland, Iraq, Iran, Ireland, Israel, Italy (Campania, Liguria, Sardinia and Venice), Jamaica, Jordan, Kazakstan, Kyrgyzstan, Kuwait, Lebanon, Luxembourg, Maldives, Moldova, Monaco, Montenegro, Morocco, Nepal, the Netherlands, North Macedonia, Oman, Palestine, Panama, Peru, Portugal, Qatar, Romania, Russia, Sint Maarten, Slovakia, Slovenia, South Africa, Spain (not Canary Islands), Tunisia, Turks and Caicos Islands, Ukraine, the United Arab Emirates, United Kingdom and the United States.
Affected people will be informed on planes, coaches and at the borders, and must register with the local authorities once in Switzerland.
Anyone who appears to be sick must not be allowed to board buses, trains or flights to Switzerland.
How has this changed over time?
The initial quarantine list had 29 countries. As of end-September, that list is now at 66.
