Latest data from today (2 pm on Friday 13th March)  means that the number of cases rose by 45 from 6pm on Thursday. So far 4,346 tests have been conducted, Nina Pirnat, director of the National Public Health Institute, told reporters.

The biggest increase in cases has been in the Ljubljana region.

"We must limit social contacts to the greatest possible extent to curb the spread of infections as much as possible," Pirnat said, calling on parents to make sure young people do not get together and socialise in groups, possibly while consuming alcohol.
