Germany has categorized individual regions in some 11 European countries as high-risk areas. Belgium and Iceland were on the list, while areas of the UK such as Wales and Northern Ireland were also included.
The French regions Pays de la Loire and Burgundy are now considered high-risk, along with various regions in Lithuania, Estonia, Ireland, Croatia, Slovenia, Hungary and Romania.
Germany classifies an area as high-risk and issues a travel warning if the number of new coronavirus infections exceeds the mark of 50 cases per 100,000 inhabitants within seven days.
The warning is not a travel ban, but is intended to deter tourist travel and enables vacationers to cancel their bookings free of charge.
Germany also announced the lifting of its general travel warning for a total of 160 countries outside the EU. Going forward, each country will now be assessed individually.

US airline giants American Airlines and United Airlines announced major layoffs as hopes for a bailout over the pandemic have faded.

The International Monetary Fund has estimated a contraction of 9.4% in regional GDP in 2020, the ILO pointed out.
