Moreover, passengers arriving from orange countries within the EU or the Schengen zone will not have to present a negative test to avoid quarantine, the government decided in a correspondence session on Saturday.
The government's Communication Office said in a press release that the changes were made based on recommendations from the EU.
What has so far been dubbed the yellow list was renamed the orange list last night. The office said that it contained countries whose epidemiological situation was deteriorating. Countries not listed as either green, meaning safe, or red, meaning high-risk, are considered orange.
Government speaker Jelko Kacin said Sunday afternoon that changes to the orange list were being coordinated and that the government would approve an updated orange list soon.
In the evening, the government said it green-listed Serbia, while parts of Croatia along the border with Slovenia were moved to the orange list from the red.
On the other hand, parts of Austria (Vienna, Vorarlberg and Tirol) and Hungary (Budapest and Gyor-Moson-Sopron), as well as parts of several other EU countries, were red-listed.
Many of the exemptions to travel restrictions remain in place, allowing several groups of people to avoid quarantine even when entering Slovenia from an orange or red-listed country without a negative test.
This will be the case for workers commuting across the border, hauliers, diplomats, foreign delegations, foreign security services employees, members of the Slovenian armed and police forces, as well as people travelling for urgent personal or business matters, and people who own property in a neighbouring country.
Moreover, the government decided that persons who test negative after having been ordered to quarantine will be allowed to cut short their quarantine.
The changes will be explained in more detail at a press conference on Monday, Kacin said.
