LJUBLJANA, Slovenia — Slovenia’s government has reintroduced mandatory use of face masks in closed public spaces and on public transport after a spike in cases of the new coronavirus in recent days.

The government on Wednesday removed Montenegro and Luxembourg from the list of safe countries that face no entry restrictions and said visitors coming from Albania or Portugal face a 14-day quarantine.

Health Minister Tomaz Gantar says Slovenia has confirmed 20 new cases since June 20. The anti-virus rules will be reviewed every two weeks, he said.

Slovenia has previously introduced entry restrictions for some countries after reopening following the lockdown. Authorities say new cases largely have been imported.

The total number of positive cases so far is 1,541 and 109 people have died.
