In reaction to the fast spread of the omicron form in the country, Germany is strengthening travel restrictions for those traveling from the United Kingdom.

The Robert Koch Institute, the country’s primary disease control agency, added Britain to its list of “virus variant regions” late Saturday. This implies that everyone coming from the United Kingdom to Germany must enter a 14-day obligatory quarantine, regardless of vaccination status.

The new limits, which will take effect at midnight on Sunday, come as the United Kingdom reports a record number of new coronavirus infections. On Saturday, there were 90,418 new cases across the country.

The United Kingdom has joined a list of eight African nations, including South Africa, on Germany’s list of “virus variant areas.”

The statement by the Robert Koch Institute follows the tightening of restrictions in other nations throughout Europe as the region confronts a fourth wave of illnesses.

Starting Sunday, France and Denmark are designated as “high risk zones,” which means that everyone who has not been vaccinated or recovered from the virus must be quarantined for 10 days. Dozens more nations have already been added to this group, including virtually all of Germany’s immediate neighbors.
