BERLIN — German authorities have added almost all Austria and Italy to the list of high-risk areas for COVID-19.

Travelers returning to Germany from countries or regions on the list, which is updated weekly, have to go into 14-day quarantine and take a test for the coronavirus.

Those with negative test results can end their quarantines.

Critics have pointed out that the threshold of 50 new cases per 100,000 inhabitants per week, which is the main criteria for determining which countries appear on the list, has now been passed in much of Germany itself.

Germany’s disease control agency reported Friday that the country saw another new daily record number of confirmed cases, with 18,681. The new cases take the country's total in the pandemic to almost half a million.
