The greater Paris region of Île-de-France and the southern Provence-Alpes-Côte-d'Azur region, which includes tourist hubs on the French Riviera, were added to the German foreign ministry's list of 'risk areas' late on Monday evening.
All travel to these areas should be avoided unless the journey is “indispensable,” according to the German foreign ministry.
Travellers who return from these areas must undergo a Covid-19 test and self-isolate for 14 days upon their return.
The travel advice for any country on the German list of risk areas states that: “Before embarking on your journey, please check whether you have spent time in one of these areas in the last 14 days before entering Germany.
“Should this be the case, you must expect to be subject to mandatory testing and quarantine.”
France has seen a surge in the number of new coronavirus cases over the past weeks, with the daily tally reaching a new post-lockdown record several days in a row last week before peaking at nearly 5,000 new cases in 24 hours on Sunday.
On Monday, the French public health agency confirmed 1,955 new cases, 15 new deaths, and 18 new clusters under investigation over the past 24 hours.
France has ramped up its national testing capacities over the past months, reaching a level of more than 635,000 tests per week according to the latest public data (up from 200,000 per week in June).
However health authorities say the rise in cases cannot solely be attributed to increased testing, as the positive testing rate (number of positive cases per 100,000) has risen to 3.6 percent.
On August 15th the UK enforced a mandatory 14-quarantine for all travellers from France, a decision that France has said it will respond to 'in the coming days'.
The rapid surge in the number of confirmed new coronavirus cases over the past weeks in France has seen the French government tighten health rules to curb the spread.
As of September 1st, masks will be compulsory both in the workplace and in schools for children aged above 11 and and teachers at all times.
