LJUBLJANA, Slovenia — Slovenia’s confirmed coronavirus cases have soared to another daily record of 1,663, and the country has reported the deaths of five more people with COVID-19.

Neighboring Croatia also set a new daily record on Thursday with 1,563 new cases and 13 deaths, most of them in the capital, Zagreb.

Authorities in both countries have warned that if the infection rates continue to climb at their current pace, hospitals could run out of unoccupied beds.

Several general hospitals in Croatia have already been turned into facilities treating only COVID-19 patients and are preparing tents to accommodate more people.

Confirmed infections now constitute over 25% of all virus tests in Slovenia, well above the 5% threshold recommended by the World Health Organization.

Health officials have called on the Slovenian government to introduce stricter measures to combat the virus spread, including a complete lockdown of the small Alpine state of 2 million people.
